3.1.2 Power-On Flowchart

FIGURE 3-1 can help you identify a Sun Blade 2500 system malfunction.

If you suspect a system of malfunction, power on the system and follow the
flowchart.

If you answer “No” to a question (conditional), direct your attention to the section
indicated or to other flowchart cross-references.

If you complete the flowchart without answering “No” to any questions yet you still
suspect a malfunction with the Sun Blade 2500 system, see Section , “Introduction to
Advanced Troubleshooting” on page 5-1 for more in-depth troubleshooting
procedures.

3.4 Other Errors

3.4.1 Colormap Flash Errors

The Sun Blade 2500 workstation ships with its Sun XVR-100 graphics accelerator
configured to 24-bit color depth.

If you experience colormap flashing (incorrect colors or color changes) when moving
your cursor from window to window, your graphics accelerator might be incorrectly
configured. If colormap flashing occurs, perform one of the following procedures to
configure your Sun XVR-100 to 24-bit or to 8+24-bit color depth.

3.4.1.1 Setting the -depth 24 Color Depth

1. Using the fbconfig command, type:

% fbconfig -dev pfb0 -depth 24

2. Log out, then log back in for the change to take effect.

Chapter 3 Basic Troubleshooting 3-17

 Note – 24-bit color depth performance might be slower than 8-bit color depth
performance.

3.4.1.2 Setting the 8+24-bit Color Depth

If both 8-bit and 24-bit graphics are to be run simultaneously (8+24-bit color depth),
Sun XVR-100 graphics accelerator patch 114537-19 or later must first be installed.

1. As superuser, download and install patch 114537-19 or later.

a. Go to the Sun web site http://sunsolve.sun.com

b. Select the Patchfinder link.

c. Enter patch ID 114537 and select the Find Patch link.

d. Download the patch.

e. Unzip the patch.

For example:

# unzip 114537-19.zip

f. Install the patch.

For example:

# patchadd 114537-19

g. Reboot the system after installing the patch by typing:

# reboot -- -r

2. Using the fbconfig command, set the Sun XVR-100 graphics accelerator to 8+24-
bit color depth.

% fbconfig -dev pfb0 -fake8 enable

3-18 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Note – Do not invoke the either of the following commands fbconfig -dev
pfb0a -fake8 enable or fbconfig -dev pfb0b -fake8 enable if patch
114537-19 is not installed, when configuring dual monitors to a single Sun XVR-100
graphics accelerator.

Note – The command fbconfig -dev pfb0 -fake8 disable turns off 8+24-
bit color depth.

3. Log out, then log back in for the change to take affect.

8-bit depth performance is slower in 8+24-bit color depth mode.

3.4.2 Fibre Channel Error

The Sun Blade 2500 does not support fibre channel. However, the following message
might appear in the /var/adm/messages file:

WARNING: fcsm: _init: Transport Layer driver ‘fp’ load failed

If this message appears, no action is necessary, and you can ignore this message.

3.4.3 SunPCi III Reboot Failure

If the Sun Blade 2500 workstation is configured with a SunPCi™ III coprocessor, the
following message might appear on the console during boot, or in the
/var/adm/messages file:

Hardware Reboot: X86 failed to respond

If this message appears, no action is necessary, and you can ignore this message.

Chapter 3 Basic Troubleshooting 3-19

3.4.4 Sun XVR-1200 Graphics Accelerator PROM
Diagnostics Error
When a Sun XVR-1200 graphics accelerator with PROM v1.10 or earlier installed
executes its self-test, the graphics accelerator incorrectly identifies itself to the
motherboard as a Sun XV-500 graphics accelerator. For example:

ok test screen
Testing screen
Starting XV-500 Selftest

Note – This diagnostic error does not affect the operation of the accelerator or
workstation.

3.4.4.1 Verifying That a Sun XVR-1200 Graphics Accelerator Is

Installed
There are several methods for verifying that a Sun XVR-1200 graphics accelerator is
installed on your workstation. Two of these methods are described below.
■ At the ok prompt, type the show-devs command and look for the following text
in the OpenBoot™ PROM output:

/pci@1f, 700000/SUNW,XVR-1200@3

Note – The Sun Blade 2500 workstation can support up to two Sun XVR-1200
graphic accelerators. Your OpenBoot PROM output text might vary to account for

5.1 About NVRAM

After the Power button is pressed, the boot PROM receives and loads workstation
configuration information from NVRAM.

NVRAM for the Sun Blade 2500 workstation is located on the motherboard at
location U47. This 64-Kbit nonvolatile random access memory (NVRAM) serial
EEPROM can be removed and transferred to another motherboard. NVRAM is a
replaceable component and can be ordered.

 NVRAM

FIGURE 5-1 NVRAM Location and Identification

5.1.1 System NVRAM Configuration Variables

System configuration variables are stored in the workstation NVRAM. These
variables determine the start-up system configuration and related communication
characteristics. You can modify the values of the configuration variables, and any
changes you make remain in effect even after a power cycle. To permanently change
a NVRAM configuration variable you must be at the ok prompt.

Note – Configuration variables should be adjusted cautiously.

5.2 Obtaining the ok Prompt

At the ok prompt, you can make changes to NVRAM and conduct OpenBoot PROM
tests. The following table lists procedures for obtaining the ok prompt, listed from
most preferred to least desirable.

5.4 About Power-On Self-Test

Power-On Self-Test (POST) is a firmware program used to identify workstation
failures. When initiated, POST verifies the core functionality of the workstation.

Chapter 5 Introduction to Advanced Troubleshooting 5-5

5.4.1 POST Overview
POST diagnostics are used to verify core functionality of the workstation. That is,
POST diagnostics are used to check operation of the CPUs, system memory, data
switches, I/O bridges, and the PCI bus.

POST diagnostic firmware occupies a section of the motherboard’s boot PROM.

POST is invoked optionally at power-on by the OpenBoot program and depends on
the setting of variables diag-switch? and diag-level. The values for diag-
switch? and diag-level are stored in nonvolatile RAM (NVRAM).

Note – POST diagnostic and error message reports are displayed on a separate
console terminal.

5.4.1.1 Controlling POST

The power-on test variables are:
■ diag-switch?
■ diag-level

Setting diag-switch? to true causes the function diagnostic-mode? to return

true. When diagnostic-mode? returns true, the system:
■ Performs more thorough self-tests during any subsequent power-on or system
reset process. The coverage of self-tests executed depends on the value of diag-
level. For maximum coverage, set the diag-level value to max.
■ Might display additional status messages. The details are implementation-
dependent.
■ Uses different configuration variables for booting (than when POST is disabled).

The Sun Blade 2500 workstation has a factory default of false for the diag-
switch. To set diag-switch? to true, type:

ok setenv diag-switch? true

ok

To set diag-switch? to false, type:

ok setenv diag-switch? false

ok

5-6 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Note – When not in diagnostic mode, the system does not announce the diagnostic
tests as they are performed (unless a test fails).

5.4.2 Using POST

When power is applied to the workstation, POST runs automatically if both of the
following conditions apply:

Chapter 5 Introduction to Advanced Troubleshooting 5-7

 ■ The diag-switch? NVRAM parameter is set to true.
■ The diag-level is set to min or max.

Note – In the event of an automatic workstation reset, POST runs if the diag-
switch? NVRAM parameter is set to true and the diag-level flag is set to either
max or min.

If the diag-switch? is set to false, POST is disabled.

If diag-switch? is set to true and diag-level is set to max, then POST runs in
max mode. If diag-switch? is set to true and diag-level is set to min, then
POST runs in min mode.

5.5 About OpenBoot PROM

5.5.1 OpenBoot PROM Overview

OpenBoot PROM is the core software installed on the Sun Blade 2500 motherboard.
This very basic software enables CPU, memory, I/O bridge, SouthBridge, and other
motherboard components to perform minimal communication tasks to initially boot
the Sun Blade 2500 to a state where it can load an operating environment from either
an installed hard disk, a DVD-ROM, CD-ROM, the network, or from some other
external boot device.

As shown in TABLE 3-3, “OpenBoot PROM Messages and Their Meaning” on page 11,
OpenBoot PROM plays a major role in system start-up. Should an error occur during
the start-up process, an OpenBoot PROM message might be displayed. The error
may occur during POST or during a time after POST diagnostics are completed and
the OpenBoot PROM brings the Solaris operating environment up.

See Section , “OpenBoot PROM” on page 8-1 for additional information.

5.5.2 OpenBoot Diagnostics

OpenBoot PROM has a collection of in-depth testing utilities and programs,
available from both the ok and obdiag prompt.

To use the testing utilities and programs, see Section , “OpenBoot PROM” on
page 8-1.

5-8 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
5.6 About SunVTS Software

5.6.1 SunVTS Overview

The Sun Validation Test Suite (SunVTS) software is a comprehensive software
diagnostic package that tests and validates hardware by verifying the connectivity
and functionality of most hardware controllers, devices, and platforms.

5.6.2 Using SunVTS

SunVTS software executes multiple diagnostic tests from one graphical user
interface (GUI) that provides test configuration and status monitoring. The user
interface can run in the CDE or OPEN LOOK environments or through a TTY-mode
interface for situations when running a GUI is not possible.

The SunVTS interface can run on one workstation to display a SunVTS test session
of another workstation on the network.

SunVTS software is distributed with each SPARCTM or Solaris release on the Sun
Computer Systems Supplement CD.

5.6.3 SunVTS Requirements

Your workstation must meet the following requirements to run SunVTS software:
■ The SunVTS packages must be installed. The main package is SUNWvts. There are
additional supporting packages that differ based on the revision of the Solaris
operating environment that is installed. For specific details, see the corresponding
SunVTS documentation.
■ The workstation must be booted to the multiuser level (level 3).
■ To run SunVTS software with a GUI, that GUI must be installed. Otherwise, run
SunVTS software with the TTY-mode interface.

5.6.4 SunVTS References

To find out more information about using SunVTS software see the SunVTS
documentation that corresponds to the Solaris release that you are running.

Chapter 5 Introduction to Advanced Troubleshooting 5-9

 The SunVTS documents are part of the Solaris on Sun Hardware AnswerBook
collection. This AnswerBook collection is preinstalled on the hard disk of new
systems. It is also distributed on the Software Supplement CD that is part of each
Solaris Media Kit release and is also accessible at http://docs.sun.com.

The following list describes the contents of each SunVTS document:

■ SunVTS 5.1 User’s Guide (816-5144) describes how to install, configure, and run
the SunVTS diagnostic software.
■ SunVTS Quick Reference Card (816-5146) provides an overview of how to use the
SunVTS CDE interface.
■ SunVTS 5.1 Test Reference Manual (816-5145) provides details about each
individual SunVTS test.
■ SunVTS 5.1 Patch Set 5 Documentation Supplement (817-4350) details new features,
tests and test enhancements that were developed for the SunVTS patch set
releases.

Note – Patch Set 5 supports Solaris 8 2/04. Subsequent and compatible versions of
Solaris 8 could require patch set 6 or later.

For additional information about using SunVTS see Section , “SunVTS” on page 9-1.

NVRAM

The workstation’s system configuration variables are stored in NVRAM. These

variables determine the startup configuration of your workstation. You can modify
the configuration variables stored in NVRAM and change the startup configuration
of your workstation by using the setenv configuration command at the ok prompt.

This chapter describes how to change your NVRAM configuration variables and
how to use your USB keyboard to abort or reset NVRAM by using the Stop-A
command or the Stop-N equivalent procedure.

Note – The Stop-A and Stop-N keys are sometimes referred to as “OpenBoot
Emergency Procedures”.

This chapter contains information about the following topics:

■ Section 6.1, “NVRAM Configuration” on page 6-1
■ Section 6.2, “Stop-A Command” on page 6-8
■ Section 6.3, “Stop-N Equivalent Command Procedure” on page 6-9

6.1 NVRAM Configuration

System configuration variables are stored in the workstation NVRAM. These
variables determine the start-up system configuration and related communication
characteristics. You can modify the values of the configuration variables, and any
changes you make remain in effect even after a power cycle. Configuration variables
should be adjusted cautiously.

In the displayed, formatted list of the current settings, numeric variables are often
shown in decimal format.

To permanently change a variable setting, type:

ok setenv variable-name value

where variable-name is the name of the variable and value is a numeric value or text
string appropriate to the named variable. A numeric value is interpreted as a
decimal number, unless preceded by 0x, which is the qualifier for a hexadecimal
number.

6-4 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 For example, to set the auto-boot? variable to false, type:

ok setenv auto-boot? false

ok

Note – Many variable changes do not affect the operation of the firmware until the
next power cycle or system reset, at which time the firmware uses the variable’s new
value.

You can reset most of the NVRAM configuration variables to the original defaults
using the set-default variable and set-defaults commands.

For example, to reset the auto-boot? variable to its default setting (true), type:

ok set-default auto-boot?
ok

To reset most variables to their default settings, type:

ok set-defaults
ok

6.1.3 Selecting Boot Options

You can use the auto-boot? configuration variable to determine whether or not the
system boots automatically after a power cycle or system reset.

If auto-boot? is true and if OpenBoot is not in diagnostic mode, the system boots
automatically after a power cycle or system reset using the boot-device and
boot-file values.

If auto-boot? is true and if OpenBoot is in diagnostic mode, the system boots

automatically after a power cycle or system reset using the diag-device and
diag-file values.

Chapter 6 NVRAM 6-5

 These variables can also be used during manual booting to select the boot device
and the program to be booted. For example, to specify default booting from the
network server, type:

ok setenv boot-device net

ok

Changes to boot-file, boot-device, diag-file, and diag-device take

effect the next time that boot is executed.

you use the boot command with an argument, a password is required.
■ The go command does not require a password.
■ A password is required to execute any other command.

6-6 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
Examples are shown in the following screen.

ok boot (password required)

ok go (no password required)
ok boot filename (password required)
Password (password is not echoed as it is typed)
ok reset-all (password required)
Password: (password is not echoed as it is typed)

Caution – Remember your security password.

Caution – Always set the security password before setting the security mode. If you
forget this password, you cannot use your system; you must call customer support
service to make your system bootable again.

To set the security password and command security mode, type the following at the
ok prompt:

ok password
ok New password (only first 8 chars are used):
ok Retype new password:
ok setenv security-mode command
ok

The security password you assign must be between zero and eight characters. Any
characters after the eighth are ignored. You do not have to reset the system; the
security feature takes effect as soon as you type the command.

Note – If you enter an incorrect security password, there is a delay of about 10

seconds before the next boot prompt appears. The number of times that an incorrect
security password is typed is stored in the security-#badlogins variable.

Full Security
The full security mode is the most restrictive. With security-mode set to full:
■ A password is required any time you execute the boot command.
■ The go command does not require a password.
■ A password is required to execute any other command.

Chapter 6 NVRAM 6-7

 Here are some examples:

ok go (no password required)

ok boot (password required)
Password: (password is not echoed as it is typed)
ok boot filename (password required)
Password: (password is not echoed as it is typed)
ok reset-all (password required)
Password: (password is not echoed as it is typed)

Caution – Always set the security password before setting the security mode. If you
forget this password, you cannot use your system; you must call customer support
service to make your system bootable again

To set the security password and full security mode, type the following at the ok
prompt:

ok password
ok New password (only first 8 chars are used):
ok Retype new password:
ok setenv security-mode full
ok

none Security
With the NVRAM security-mode set to none a password is not required. This is
the default condition for NVRAM.

6.2 Stop-A Command

Use the Stop-A command to abort an OpenBoot process. When issuing the Stop-A
command for the Sun Blade 2500 workstation, press both the Stop and A keys
immediately after powering on the workstation. Hold both keys down until the
workstation beeps.

Note – Using Stop-A does not allow the workstation to perform a core dump. This
information could be useful to you if the operating environment has crashed.

6-8 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Note – Before issuing a Stop-A command, ensure that the keyboard is connected to
USB0 or USB1.

6.3 Stop-N Equivalent Command Procedure

The Sun Blade 2500 workstation uses a USB Type-6 keyboard. Workstations that use
USB type 6 keyboards cannot use the old Stop-N command to reset workstation
configuration variables. Instead, the following Stop-N equivalent procedure must be
used to reset your workstation configuration variables.

To reset NVRAM configuration variables temporarily perform the following

procedure:

1. Power on the workstation and wait until the front panel Power button LED begins
to blink and you hear an audible beep.

2. Quickly press the front panel Power button twice (as you would double-click a
mouse).
A screen similar to the following is displayed to indicate that you have successfully
reset NVRAM contents to the default values. If a screen does not appear repeat steps
1 and 2.

Safe NVRAM mode, the following nvram configuration variables have

been overridden:
’diag-switch?’ is true
’use-nvramrc?’ is false
’input-device’, ’output-device’ are defaulted
’ttya-mode’, ’ttyb-mode’ are defaulted

These changes are temporary and the original values will be restored
after the next hardware or software reset.

ok

Chapter 6 NVRAM 6-9

 The Stop-N equivalent command resets some of the NVRAM configuration variables
to their defaults (TABLE 6-4). For example, TTYA mode settings are reset to their
default values.

When Stop-N is started, the workstation NVRAM settings are only reset to their
defaults for a single power cycle.

Note – If you use the Stop-N equivalent command to reset the system at this point,
the NVRAM settings are not permanently changed.

Typing set-defaults discards any customized NVRAM values and permanently

restores the default settings for all NVRAM configuration parameters.

Note – Once the Power button LED stops blinking and stays lit, pressing the Power
button again powers off the system.

You can however manually change each NVRAM setting. To view and change
NVRAM setting see “System NVRAM Configuration Variables” on page 2.

CHAPTER 7

Power-On Self-Test

This chapter describes how to prepare for and initiate power-on self-test (POST)
diagnostics for the Sun Blade 2500 workstation.

This chapter contains the following topics:

■ Section 7.1, “Preparing for POST Diagnostics” on page 7-1
■ Section 7.2, “Setting Up POST” on page 7-6
■ Section 7.3, “Maximum, Minimum, and Menu Levels of POST” on page 7-7
■ Section 7.4, “Analyzing POST Results” on page 7-20

7.1 Preparing for POST Diagnostics

Before running POST:
■ You must also verify baud rates between the workstation and a monitor or the
workstation and a terminal.
■ You must first configure a terminal interface processor (TIP) connection to another
workstation or to an external terminal to view POST progress, error, warning, or
information output messages.

7-1
7.1.1 Verifying the Baud Rate
To verify the baud rate between the workstation under test and a terminal or another
Sun workstation monitor:

1. Open a terminal window.

2. Type eeprom

Note – eeprom is a Solaris command.

3. Verify the following serial port default settings as follows:

ttyb-mode = 9600,8,n,1,-
ttya-mode = 9600,8,n,1,-

Note – Ensure that the settings are consistent with TTY-type terminal or system
monitor settings.

4. If the serial port default settings are not correct see Section 7.1.2, “Setting the
Baud Rate” on page 7-2.

7.1.2 Setting the Baud Rate

● From the ok prompt of the workstation under test, type:

ok setenv ttya-mode=9600,8,n,1,-

7-2 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
7.1.3 Setting Up a TIP Connection
A TIP connection enables a terminal window in a remote workstation to be used as
a terminal for display of workstation diagnostic and test data. Serial0 port of a tested
Sun Blade 2500 workstation is used to establish a TIP connection between the Sun
Blade 2500 workstation being tested and another Sun workstation monitor or
terminal.

To set up a TIP connection:

1. Use a 3-wire null modem cable to connect serial0 port of the Sun Blade 2500
workstation under test to the serial port of another Sun system (connect cable pins
2-3, 3-2, 4-GND, and 5-GND).

Note – Not all Sun systems have 3-wire null modem cables shipped with them.
These cables are available through your local computer hardware store.

FIGURE 7-1 Setting Up a TIP Connection—DB9 Connector to DB9 Connector

Note – With the use of an RJ45 to DB9 adapter, it is possible to use two RJ45
connectors and a length of ethernet cable to establish a TIP connection between
workstations. Use FIGURE 7-1 as a guide to connect the DB9 workstation serial
connector under test to a second DB9 serial port of another Sun system. It is also
possible to use two RJ45 connectors and a length of ethernet cable to establish a TIP
connection between workstations with DB9 and DB25 serial ports. Use as a guide to
connect the DB9 workstation serial connector to a DB25 serial port.

/cables_ext_data.html

2. At the other Sun system, check the /etc/remote file by changing to the /etc
directory and then editing the remote file:

hardwire:\
:dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

Note – The example shows connection to the serial port of the other Sun system.

3. To use a different serial port, such as a, modify the /etc/remote file as follows:

hardwire:\
:dv=/dev/term/a:br#9600:el=^C^S^Q^U^D:ie=%$:oe=^D:

4. In a shell (terminal) window on the other Sun system, type tip hardwire.

% tip hardwire
connected

7-4 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Note – The shell (terminal) window is now a TIP window directed to the serial port
of the Sun Blade 2500 workstation being tested. When power is applied to the Sun
Blade 2500 workstation under test, its POST messages will be displayed in this
window.

5. When POST is completed, disconnect the TIP window as follows:

a. Open a terminal window.

Open the terminal window on the other Sun system.

b. Type ps -a to view the active TIP line and process ID (PID) number.

c. Type the following to kill the TIP hardwire process.

% kill -9 PID#

Note – You can also type ~ in the TIP window to kill the TIP hardware process.

7.1.4 Viewing POST Output From an External Display

Device
POST directs its output to the serial port of the system being tested. You can view
this output by connecting a serial terminal or a second system running a TIP
connection through a terminal window.

7.1.4.1 Serial Terminal

You can view POST output through any RS-232 compatible serial terminal. Use a
straight-through cable and connect the workstation to the serial terminal’s Data
Communications Equipment (DCE) port. Configure the serial terminal to the
communication parameters listed in TABLE 7-1.

TABLE 7-1 Serial Terminal Communication Parameters

Parameter Value

Baud 9600
Data bits 8
Parity None

Chapter 7 Power-On Self-Test 7-5

 TABLE 7-1 Serial Terminal Communication Parameters (Continued)

Parameter Value

Stop bits 1
Handshaking None
Duplex Full

If a DCE port is not available, then use a crossover cable as described in FIGURE 7-1.

7.1.4.2 Second System

Instead of a serial terminal, you can use a second system running a TIP connection
through a terminal window.

The second system must have a serial port capable of RS-232 communications. Use a
crossover cable with the TIP connection.

FIGURE 7-1 shows the wiring for a crossover cable. If your system does not have a
DB-9 connector at its serial port, adapters are available from most computer supply
stores.

The following URL provides part numbers for adapters and other Sun cables:

Devices/Cables/cables_ext_data.html

7.2 Setting Up POST

POST can be run and monitored from an OpenBoot PROM environment using the
Sun Blade 2500 workstation. You can also run POST from the Sun Blade 2500
workstation and monitor its operation from an attached dumb terminal.

7.2.1 Setting Up POST to Run in an OpenBoot PROM

Environment
To run POST in an OpenBoot PROM environment you must:
■ Set the diag-switch? to true
■ Set the diag-level to max or min
■ Power cycle the workstation.

7-6 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Note – The default setting for diag-switch? is false. The default setting for
diag-level is normally min. However the diag-level may have been
previously set to off.

To set the diag-switch? to true, do the following:

1. At the system prompt, type:

ok setenv diag-switch? true

ok setenv diag-level min or max or menu

Note – At the system prompt, type: setenv diag-level min or max.

2. Press and hold the power button for 5 seconds to power cycle the workstation.
After the workstation has powered down wait 4 seconds before pressing the power
button to power-on the workstation.

7.3 Maximum, Minimum, and Menu Levels

of POST
Three levels of POST are available for the Sun Blade 2500 workstation:
■ maximum (max)
■ minimum (min)
■ menu

The Sun Blade 2500 is shipped by default not to run POST. POST is switched off
when the workstation is powered on for the first time. If you wish to run POST you
must first set the diag-switch? and diag-level. For additional information see:
Section 6.1.1, “NVRAM Configuration Variables” on page 6-2 and Section 6.1.2,
“Displaying and Changing Configuration Variable Settings” on page 6-3.

7.3.1 Maximum Level of POST

The workstation initiates the selected level of POST based on the diag-level
setting.

Chapter 7 Power-On Self-Test 7-7

 Note – diag-level is an NVRAM configuration variable (see Section 5.1.1,
“System NVRAM Configuration Variables” on page 5-2).

When this OpenBoot flag is set to max, POST runs the maximum number of tests
possible. This max mode greatly increases the amount of memory testing performed.
These memory tests can run for up to 10 minutes or more depending on the system
configuration of the workstation. Multiple CPU configurations combined with
different amounts of installed memory also affect the time required for the
workstation to complete POST.

The following table lists the approximate amount of time required for a Sun Blade
2500 workstation to complete the maximum and minimum levels of POST with 2
CPUs and 8 Gigabytes of memory installed. These approximate POST completion
times are based on 8 Gigabytes of memory installed with the diag-level variable
set to max or the diag-level variable set to min. The approximate POST
completion times also vary with the number of CPUs configured to the system.

TABLE 7-2 Approximate POST Completion Times

Amount of DIMM
CPU Configuration Memory diag-level max Setting diag-level min Setting

2-CPUs 8.0 GB 7 minutes, 37 seconds 2 minutes, 44 seconds

To set the diag-level variable to max, type:

ok setenv diag-level max

To return POST to the off setting, type:

ok setenv diag-level off

Note – In this example the NVRAM configuration variable setenv diag-level

off turns POST off. Normally you should type set-default variable is to restore
system variables to their factory defaults. See, Section 6.1.2, “Displaying and
Changing Configuration Variable Settings” on page 6-3.

7-8 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
7.3.2 Minimum Level of POST
When this OpenBoot PROM flag is set to min, POST runs the minimal amount of
testing necessary to test the workstation. This minimal mode mostly affects the
amount of memory testing performed.

To set the diag-level variable to min, type:

ok setenv diag-level min

To return to the default setting, type:

ok setenv diag-level off

Note – In this example the NVRAM configuration variable setenv diag-level

off turns POST off. Normally you should type set-default variable is to restore
system variables to their factory defaults. See, Section 6.1.2, “Displaying and
Changing Configuration Variable Settings” on page 6-3.

7.3.3 Menu Level of POST

When this OpenBoot PROM flag is set to menu, POST does not run any test. POST
will configure the workstation and stop at the POST menu. From the POST menu,
the user can then run selected POST tests in a controlled sequence.

To set the diag-level variable to menu, type:

ok setenv diag-level menu

ok reset-all

To return to the default setting type:

ok setenv diag-level off

ok reset-all

Chapter 7 Power-On Self-Test 7-9

7.3.3.1 Menu Control of POST
Once the user is at the POST menu, control menus are selected by typing a menu
number followed by a return (enter key). The menus are made up of multiple levels.
Follow the on-screen selection until you arrive at the desired test menu.

7.3.4 diag-level Configuration Variable Set to max

When the diag-level configuration variable is set to max, POST enables an
extended set of diagnostic-level tests for the workstation. The following tests are
performed in this order:

1. All CPUs do full memory test

2. Slave CPUs test IO-Bridge0 and IO-Bridge1

3. Master CPU performs an Init of critical resources

4. Master CPU test

5. Master CPU I2C

6. Master CPU memory test

7. Slave CPU test

8. Slave CPU memory test

9. Master CPU test of Slave CPU’s memory

10. Slave CPU executes POST from master memory

11. All CPUs test internal cache

12. All CPUs scrub memory

13. Master CPU tests both IO-Bridge0 and IO-Bridge1

Note – See TABLE 7-2 for approximate POST completion times.

7.3.5 diag-level Configuration Variable Set to min

When the diag-level variable is set to min, POST enables an abbreviated set of
diagnostic-level tests. The following tests are performed in this order:

7-10 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
1. Master CPU performs an Init of critical resources

2. Master CPU test

3. Master CPU I2C

4. Master CPU memory test

5. Slave CPU test

6. Slave CPU memory test

7. Master CPU test of slave CPU’s memory

8. Slave CPU executes POST from master memory

9. All CPUs test internal cache

10. All CPUs scrub memory

11. Master CPU tests both IO-Bridge0 and IO-Bridge1

Note – See TABLE 7-2 for approximate POST completion times.

The following post output example is a sample of the serial port POST output with
the diag-level configuration variable set to min for 2-CPU, 4 Gbyte memory
workstation configuration:

Sun Blade 2500, No Keyboard

Copyright 1998-2002 Sun Microsystems, Inc. All rights reserved.
OpenBoot 4.x.build_18, 4096 MB memory installed, Serial
#52427535.
Ethernet address 0:3:ba:1f:fb:f, Host ID: 831ffb0f.

Skipping diagnostic script because diag-script = none

{0} ok

7.3.6 POST Progress and Error Reporting

In most cases, POST also attempts to send a failure message to the POST monitoring
system. The following code example shows the typical appearance of a failure
message.

Note – The workstation does not automatically boot if a POST error occurs. The
workstation halts at the ok prompt to alert the user to a failure.

CODE EXAMPLE 7-2 Sample POST Output Error Message

{0}ERROR: TEST = * Memory marching Initial area TESTID = 68
{0}H/W under test = MAIN MEMORY
{0} Fault address 00000000.00000090
{0} Fault status 00000002.0000004f
{0} (CE) Correctable system data ECC error
{0} CPU data bit 6
{0} Memory data bit 146
{0} DIMM connector J0406
{0} Connector pin 124
{0} CPMS Slice 1

7.3.7 Controlling POST Diagnostics

You can control POST diagnostics by setting the OpenBoot configuration variables in
NVRAM. Changes to OpenBoot configuration variables will take effect only after the
workstation is restarted.

Chapter 7 Power-On Self-Test 7-19

 Note – The OpenBoot configuration variables are also known as the system
configuration variables. See Section TABLE 6-1, “Standard Sun Blade 2500 NVRAM
Configuration Variables” on page 6-2. These variables affect both POST and
OpenBoot Diagnostics.

7.4 Analyzing POST Results

POST uses the following three categories of message reporting to alert users to
workstation malfunctions:
■ Error messages
■ Warning messages
■ Information messages

All three message reporting categories start with tags indicating ERROR, MESSAGE, or
INFO.

7.4.1 Error Messages

Error messages are enclosed by the ERROR and END_ERROR tags. The name of the
error-generating test is printed on the first line of the error message. Next, a list of
potential replaceable components that might have generated the error is listed on the
second and subsequent lines of the error message after the H/W under test= tag
(see CODE EXAMPLE 7-3). Next, a list of replaceable components potentially causing
the error is listed. The replaceable components are listed in order of relevance to the
error. That is, the first replaceable component listed has a higher likelihood of
causing the specified error than the second, third, or fourth component listed.

Note – Depending on the error message, the content of the message might span
several lines.

8.4 Invoking OpenBoot Diagnostics
This section describes how to invoke OpenBoot Diagnostics.

8.4.1 Invoking OpenBoot Diagnostics

OpenBoot Diagnostics are invoked either at the workstation monitor or remotely
through an external display device.

Note – An advantage of running OpenBoot Diagnostics through a tip connection is

that long output can be scrolled and saved.

To start OpenBoot Diagnostics:

1. Obtain the ok prompt.

See Section 5.2, “Obtaining the ok Prompt” on page 5-2.

2. At the ok prompt, type:

ok setenv diag-switch? true

diag-switch? = true

3. Type:

ok setenv diag-level max

diag-level = max

4. Type:

ok setenv diag-script normal

diag-script = normal

5. Type:

ok setenv auto-boot? false

auto-boot? = false

Chapter 8 OpenBoot PROM 8-13

 6. Type:

ok reset-all

Note – OpenBoot Diagnostics will not reliably operate after a halt from UNIX
occurs. OpenBoot Diagnostics should only be run after a system reset has occurred.

7. Verify that the platform resets (see the following code example).

8.4.2 About the OpenBoot Diagnostics Menu

Once invoked, OpenBoot Diagnostics polls the workstation for device nodes. If a
component is IEEE 1275 compliant, then its connection can be tested. If the device
has a self-test, its function can be verified. When the poll is finished, OpenBoot
Diagnostics lists a menu of the diagnostics which can be executed (see
CODE EXAMPLE 8-7).

The menu of diagnostics displayed is dynamic in that if a device node is not

recognized, it is not listed in the menu. For example, if the XVR-500 graphics
accelerator were to be removed from the workstation, its test would not be available,
and all remaining tests would shift location and drop a digit (see CODE EXAMPLE 8-8).

8.5 Configuring OpenBoot Diagnostics
OpenBoot Diagnostics can be configured for running simple tests. To do so, follow
this procedure:

1. At the OpenBoot Diagnostics prompt, set the number of diagnostic passes to 1.

Type:

obdiag> setenv diag-passes 1

2. Set the diagnostic level to maximum. Type:

obdiag> setenv diag-level max

3. Set the diagnostics to be verbose and perform subtests for external devices. Type:

obdiag> setenv test-args verbose,subtest,bist

Note – These settings are stored in the NVRAM and survive power cycling.

8.6 OpenBoot Diagnostics Menu Commands

The following menu is displayed when the help command is executed.

Command Description

exit Exits obdiag tool

help Prints this help information
setenv Sets diagnostic configuration variable to new value.
test-all Tests all devices displayed in the menu.
test 1,2,5 Tests devices 1, 2, and 5.
except 2,5 Tests all devices except devices 2 and 5.
what 1,2,5 Prints some selected properties for devices 1, 2, and 5.

CHAPTER 9

SunVTS

This chapter describes using the SunVTS software to troubleshoot problems with the
Sun Blade 2500 workstation. Topics include:
■ Section 9.1, “Installing SunVTS” on page 9-1
■ Section 9.2, “Exercising System Components Using SunVTS Software” on page 9-2
■ Section 9.3, “Further SunVTS Testing” on page 9-13

9.1 Installing SunVTS

SunVTS software is operating-environment specific. Use only version 5.1 PS2 or
later, which supports the Sun Blade 2500 workstation.

You can find the latest version of SunVTS software on the web at:

http://www.sun.com/oem/products/vts/

Note – The web site can also provide you with SunVTS installation instructions. The
installation and removal instructions for SunVTS are located in the SunVTS 5.1ps2
User’s Guide.

You can find the latest revision of the SunVTS documentation on the web at:

http://diagnostics.sfbay/

9.2 Exercising System Components Using
SunVTS Software

9.2.1 Connection Mode

When configured for connection mode, SunVTS software makes a single testing
pass, checking for the existence of the item under test. Regardless of the test result,
output messages are displayed.

Note – Connection mode checks the connectivity to each device, not the device
itself.

If a component fails a test in connection mode, check that the component is

connected to the workstation and check that the connections of the component are
correctly seated and not damaged. For example, if the DVD-ROM drive test
(c0t2d0(dvdtest)) displays an error, checks that the DVD-ROM signal cable is
connected to the motherboard and checks that the cable connections on the DVD-
ROM drive are correctly seated and are not damaged.

Note – You cannot test graphics accelerators in connection mode.

Note – Many of the simplified connection mode tests are described in this section.
However, all connection and functional mode testing for your workstation is beyond
the scope of this manual. Additional connection, functional, exclusive, online, and
auto config mode testing is described in the SunVTS 5.1 PS2 Test Reference Manual.

9.2.2 Connection Mode Component Testing

To test a specific component in connection mode, follow this procedure. If you want
to test more than one component, test one component at a time, and restart the
procedure from Step 4 for the second and subsequent components.

9-2 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 1. As superuser, open a terminal window and start the SunVTS software:

# /opt/SUNWvts/bin/sunvts

The SunVTS GUI is displayed.

2. From Select Test Mode, check Connection.

3. From System Map, check Logical.

4. From Select Devices, check None.

5. Use TABLE 9-1 for the next steps, depending upon which component you want to
test.

Note – Before testing connections between the workstation SEEPROMs and DIMMs
verify that a DIMM occupies the DIMM connector under test. If a DIMM is not
present, the component mode test for that component and DIMM is not displayed
and the component test is not run.

Note – Between individual connection mode tests it maybe necessary to click Reset
to clear other workstation errors.

Signature = 0x5b0c24
Probable_Cause(s): <Device failure> Recommended_Actions(s): <Call your
authorized SUN service provider> (run_on_error message 2)

This error is displayed when the graphics accelerator is tested in functional mode.
Because the graphics accelerator is being used for the GUI, the error is created and
can be ignored.

9.2.4 Functional Mode Component Testing

To test a specific component in functional mode, do the following procedure. If you
want to test more than one component, restart this procedure from Step 6 for the
second and subsequent components.

1. As superuser, open a terminal window and start the SunVTS software:

# /opt/SUNWvts/bin/sunvts

The SunVTS GUI is displayed.

2. From Select Test Mode, check Functional.

3. From System Map, check Logical.

4. From the Options menu, select Test Execution and set Max Passes to 1.
To exercise the component more, set for more passes. Use the time for one pass in
TABLE 9-2 to determine your total test time.

5. Click Apply.

6. From Select Devices, check None.

Chapter 9 SunVTS 9-9

 7. Use TABLE 9-2 for the next steps, depending upon which component you want to
test.

Note – Before testing workstation SEEPROMs and DIMMs, verify that a DIMM

10.1 Safety Information

This section describes the safety precautions to follow when servicing a Sun Blade
2500 workstation.

10-1
10.1.1 Safety Precautions
For your protection, observe the following safety precautions when setting up your
workstation:
■ Follow all cautions, warnings, and instructions marked on the workstation and
described in Important Safety Information for Sun Hardware Systems (816-7190-10).
■ Follow the cautions, warnings, and instructions in the Sun Blade 2500 Workstation
Safety and Compliance Guide (816-2061). The document is available at:
http://www.sun.com/documentation
■ Ensure that the voltage and frequency of your power source match the voltage
and frequency marked on the workstation’s electrical rating label.
■ Never push objects of any kind through openings in the workstation. Dangerous
voltages might be present. Conductive foreign objects could produce a short
circuit that could cause fire, electric shock, or damage to your workstation.

10.1.2 Safety Symbols

The following symbols appear in this book. Note their meanings:

Caution – There is a risk of personal injury and equipment damage. To avoid

personal injury and equipment damage, follow the instructions.

Caution – Hot surface. Avoid contact. Surfaces are hot and may cause personal
injury if touched.

Caution – Hazardous voltages are present. To reduce the risk of electric shock and
danger to personal health, follow the instructions.

10-2 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
10.1.3 Electrostatic Discharge Safety
Devices sensitive to Electrostatic discharge (ESD) such as the motherboard, DIMMs,
PCI cards, media drives, and the NVRAM require special handling.

Caution – The circuit boards and hard drives contain electronic components that
are extremely sensitive to static electricity. Ordinary amounts of static electricity
from clothing or the work environment can destroy these components. Wear an
antistatic wrist strap when handling the media drive assemblies, circuit boards,
processors, DIMMs, PCI cards, and NVRAM. When servicing or removing
workstation components, attach an antistatic strap to your wrist and then to a metal
area on the workstation chassis. Then disconnect the power cord from the
workstation and the wall receptacle. Following this caution equalizes all electrical
potentials within the workstation.

10.2 Required Tools

The workstation was designed to be serviced with the following tools (FIGURE 10-1):
■ No. 2 Phillips screwdriver
■ Antistatic wrist strap
■ Antistatic mat

Antistatic mat

No. 2

Antistatic wrist strap

FIGURE 10-1 Required Tools

Chapter 10 Preparing to Replace Components 10-3

 Though not required for component replacement, the following tools may prove
helpful:
■ Needle nose pliers or hemostat
■ Large jeweller’s screwdriver
■ Flashlight
■ Digital voltage meter (DVM)

Place ESD-sensitive components such as the motherboard, memory, PCI cards, hard
drives, and the NVRAM on an antistatic mat.

10.3 Powering Off the Workstation

Prior to performing any installation or replacement procedure, power off the
workstation and all peripheral units.

Caution – Prior to powering off the workstation power, save any open files and
close any active applications. Notify affected users that you are powering off your

10.3.2 Powering Off Methods

There are two methods for powering off the workstation.
■ Graceful - This is the normal and preferred method for powering off the
workstation.
You are prompted to save all open files and close all applications prior to
shutdown. The operating environment halts or terminates all necessary system
processes and powers off the workstation.
■ Forced - Use this only when you cannot shutdown the workstation gracefully.
All open applications and files will be closed abruptly without saving any
changes. However the file system might be corrupted.

10.3.3 Shutting Down Gracefully

Performing a graceful shutdown ensures all your data is saved and the workstation
systems are ready for restart.

Chapter 10 Preparing to Replace Components 10-5

 To power off the workstation gracefully:

1. Notify affected users.

Typically, the system administrator sends an electronic notice to all users of the
affected equipment shutdown by using the write or wall commands. If you are
functioning as the system administrator, see your Solaris system administration
documentation for additional information about the write and wall commands.

2. Save any open files and quit all running programs.

See your application documentation for specific information on these processes.
Typically, this means executing application-specific commands through a GUI menu
or command line.

3. Select a power-off method.

■ Manual
■ GUI
■ Command line
Powering off the system using any of these methods shuts down all system
processes, synchronizes the files, and powers off the system.
To power off manually:

a. Press and release either the:

Power button on the front panel of the workstation (FIGURE 10-2)
or
Sleep key on the keyboard

b. At the ok prompt, type:

power-off

To power off using the GUI:

a. Select the Exit button on the CDE panel.

This logs out of the CDE workstation system GUI. The CDE GUI is closed and the
log on screen is displayed.
Optionally, you can use this method when you want to log out as one user and
login again as another user. This method does not take the workstation to a
powered-down state.

b. From the Power Off menu, select:

Shutdown

10-6 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 To power off using the command line:

a. As superuser, in a terminal window, at the prompt type either of the following:

# shutdown

or

# init 5

The shutdown command provides options for automatically notifying the users
of a scheduled shutdown. See the shutdown man page for additional
information.
Use the init commands to invoke specific restart processes. Some processes
apply to the currently running instance, others upon next system boot. See
TABLE 10-1 for a brief description of the init shutdown options. See the init
man page for descriptions of the state options and init syntax.

TABLE 10-1 Init Command Shutdown Options

Option Purpose

0 Reboots the system to the firmware level.

1 Reboots the system to system administrator mode. All files are accessible and no
users are logged onto the system.
5 Shuts down the system so that it is safe to remove the power.
6 Stops the operating system and reboots to the state specified in the init default
entry in the /etc/inittab file.

4. Verify that the power is off.

Check that the system fans are not spinning.

5. Power off and disconnect all attached external peripherals (FIGURE 10-3).
Power off and disconnect all external peripherals such as the mouse, keyboard,
monitor, and the network.

FIGURE 10-3 Disconnecting Attached Peripherals

Caution – Pressing the Power button does not remove all power from the system.
Standby power remains until the power cord is removed.

6. Remove all power to the workstation.

When the system is powered off, it is safe to open the workstation to provide access
to internal components. Proceed to Section 10.4, “Removing the Access Panel” on
page 10-12 where you will be directed to remove all power to the workstation.

Note – The power supply power connector may have a vertical or horizontal
orientation. This is defined by the vendor of your power supply (FIGURE 10-3).

10.3.4 Performing a Forced Shutdown

Use a forced shutdown only when you cannot perform a graceful shutdown. If at
any point in these procedures your system becomes able to take direction, return to
the graceful shutdown procedure.

10-8 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 Caution – If you use the forced shutdown method, all unsaved data changes are
lost and the file system might be corrupted.

To force the workstation to power down:

1. Identify all workstation hung processes.

a. If needed, rlogin or telnet to the hung system from another system.

b. From the command line in a terminal window, execute a ps command to

identify the process ID number.
See the respective man pages for syntax information.

2. Terminate a hung process, if needed.

The shutdown commands described here are used to close a system shell or stop an
application or process. They do not take the workstation to a powered-down state.

Execute these commands from the command line in a terminal window. See the
command man page for syntax information.
■ System Exit - Use the exit command to stop all processes in a specified shell and
close out the shell. Use this method when an application or process is frozen in
the shell and you have decided to force the shell to stop action and release the
system. This typically exits any child process initiated through this shell, but
background processes may continue to run. It may be necessary to execute this
command from another workstation or another terminal window. If you are in a
GUI, click the close box on the terminal window.
■ Process Kill - Use the kill command to shut down a single process. Use this
command when an application or process is frozen and you have decided to force
it to quit and release the system. It may be necessary to execute this command
from another workstation or another terminal window.
If either of these commands releases your system, return to the graceful shutdown
procedure. See Section 10.3.3, “Shutting Down Gracefully” on page 10-5.

3. Manually synchronize the system.

As superuser, in a terminal window, type:

# sync

Use the sync command when powering off a workstation to ensure file system
integrity. The command flushes all previously unwritten system buffers out to the
disk. See the sync man page for additional information.

Chapter 10 Preparing to Replace Components 10-9

 4. Press and hold the Power button for five seconds.
This abruptly stops all applications, tools, system processes. All unsaved data
changes are lost and the workstation is powered off.

Caution – A forced shutdown can corrupt your data and system files if it is
performed before the system is synchronized.

Once this is complete, you have powered off your workstation. However, you have
not removed all power from your workstation.

Caution – Pressing the Power button does not remove all power from the system.
Standby power remains until the power cord is removed.

7. Remove all power to the workstation.

When the system is powered off, then it is safe to open the workstation to provide
access to internal components. Proceed to Section 10.4, “Removing the Access Panel”
on page 10-12, where you will be directed to remove all power to the workstation.

Chapter 10 Preparing to Replace Components 10-11

10.3.4.1 Workstation Power Cycling
Either one of the following two methods accomplishes a workstation power cycle by
shutting down and immediately restarting the workstation:
■ System reboot

A system reboot shuts down any running applications and the operating system,
then restarts the operating system. A system reboot does not take the workstation
to a standby power state.
■ Shutdown and Power On
Powering off the workstation shuts down any running applications and the
operating system, and takes the workstation to a standby (power off) state. To
restart the workstation, you must manually press the Power button, which
initiates the boot process.

Note – You must wait four seconds after powering off the workstation to power-on
the workstation.

10.4 Removing the Access Panel

1. Power off the workstation.

If you have not already done so, complete the procedure in Section 10.3, “Powering
Off the Workstation” on page 10-4.

2. Locate the access panel.

Facing the workstation bezel, the access panel is on the left side of the chassis.

3. Loosen the captive thumbscrews (FIGURE 10-6).

Turn the captive thumbscrews, located at the back of the system, counter-clockwise.
If the thumbscrews are very tight, use a No. 2 Phillips screwdriver to loosen them.

11.1 Replacing DIMMs

This section describes removal and installation of the system Dual Inline Memory
Modules (DIMMs). Topics include:
■ Section 11.1.1, “Identifying the DIMMs” on page 11-2
■ Section 11.1.2, “Removing DIMMs” on page 11-4
■ Section 11.1.3, “Installing the DIMMs” on page 11-7

You can also view an animated version of these instructions by clicking on

this film icon.

11.1.1 Identifying the DIMMs

Sun Blade 2500 memory is installed as matched pairs of DDR1 SDRAM DIMMs.
Within a matched pair, DIMMs must be from the same manufacturer with the same
type and number of memory devices, the same amount of memory per device, and
the same memory speed.

DIMMs must be installed on the motherboard in consecutive connector slots. The

workstation requires a minimum of one pair of matching 512 MB or 1 GB DIMMs
installed in connector slots DIMM2 and DIMM3.

Before replacing Sun Blade 2500 memory, verify that the latest version of OpenBoot
PROM, system firmware, and recommended system patches are installed on your
system. If necessary, check the Sun System Handbook at SunSolve Online:

 The Sun Blade 2500 workstation has four DIMM connector slots above each CPU.

CPU0 has four memory slots. The two lower slots make up physical Bank 0 and
the two upper slots make up physical Bank 2 (FIGURE 11-8).

CPU1 has four memory slots. The two lower slots make up physical Bank 0 and the
two upper slots make up physical Bank 2 (FIGURE 11-8).

OpenBoot PROM references memory by bank if a problem is found. For example, if

each DIMM of a DIMM pair is from a different manufacturer the following error will
be displayed:

NOTICE - CPU0 Bank 0 DIMMS are from different vendors.

This message means that each of the two DIMMs in the lower slots comes from a
different manufacturer. The system still attempts to use the DIMMs.

NOTICE - CPU0 Bank 2 DIMMs have different architectures and will

not be used.

This message means that each of the two DIMMs in the upper slots has a different
internal memory layout. The system will not use the DIMMs.

11.5.5 Special Considerations for Multiple Graphic

Accelerators Installed in a Single Workstation
A single Sun Blade 2500 can support multiple Sun XVR-100, Sun XVR-500, Sun XVR-
600, and Sun XVR1200 graphics accelerators. TABLE 11-6 describes the recommended
PCI slot locations for the recommended Sun graphics accelerators.

TABLE 11-6 PCI Slot Locations for Sun Blade 2500 Graphics Accelerators

Number of Graphics
Graphics Accelerator Accelerators Supported PCI Slot Location(s)

Sun XVR-100 3 PCI2, PCI3, or PCI5

Sun XVR-500 2 PCI2, PCI3, or PCI5
Sun XVR-600 3 PCI2, PCI3, or PCI5
Sun XVR-1200 2 PCI2, PCI3, or PCI5

11.5.5.1 Visual Inspection

If the firmware does not configure a console display, you can determine the default
console display by inspecting the back panel of the workstation. If a single graphics
accelerator is installed into the PCI slot 5, then that card is the default console
display. If there is no graphics accelerator installed into slot PCI5, consider the probe
order described in TABLE 11-7.

11-38 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
11.5.5.2 Probe Order
During the boot sequence, device nodes are probed. The PCI slots are probed in the
order described in TABLE 11-7:

TABLE 11-7 PCI Card Probe Order

Probe
Order Slot Identifier Slot Position on Back Panel Device Node

1 PCI5 Top slot /devices/pci@1f,700000 device 3

2 PCI4 Second slot from top /devices/pci@1e,600000 device 2

3 PCI1 Second slot from the bottom /devices/pci@1e,600000 device 3

4 PCI0 Bottom slot /devices/pci@1e,600000 device 4

5 PCI2 Third slot from the bottom /devices/pci@1e,600000 device 5

6 PCI3 Fourth slot from bottom /devices/pci@1e,600000 device 1

Unless you reconfigure the default, the first graphics accelerator occurring in the
probe order is designated the default console display and assigned the aliases
screen and /dev/fb.

11.5.5.3 Identifying the Default Console Display

The test screen command issued at the ok prompt requests the default console
display to execute a self-test, thereby identifying itself. The self-test checks memory
and might display color bars on the monitor. If the ok prompt is accessed from an
external display device like a serial terminal or TIP connection, then test information
is output to that connection. For example:

ok test screen
Testing screen

Starting XV-100 Selftest

(This will take an estimated
2-4 minutes for the full test)
. . .

This is the beginning of the self-test output for a Sun XVR-100 graphics accelerator.

If the device does not have a self-test built in, the following message is displayed.

screen device has no selftest method

Chapter 11 Replacing the Motherboard and Associated Components 11-39

11.5.5.4 Changing the Console Display
You can configure the OpenBoot PROM to designate a different graphics accelerator
as the console display. Use the show-displays utility, the nvalias command, and
the output-device parameter to make this change. For the following example, a
Sun XVR-100 graphics accelerator is installed in slot PCI5 and a Sun XVR-1200
graphics accelerator is installed in slots PCI2 and PCI3. Initially, the Sun XVR-100
graphics accelerator is the default console display. This example configures the Sun
XVR-1200 graphics accelerator to be the new console display.

1. Obtain the ok prompt.

See Section 5.2, “Obtaining the ok Prompt” on page 5-2.

2. Display the device nodes for the installed graphics accelerators. For example:

ok show-displays
a) /pci@1f,700000/SUNW,XVR-100@3
b) /pci@1e,600000/SUNW,XVR-1200@1
q) NO SELECTION

3. Select the graphics accelerator to be the new console display by typing its
respective letter. For example:

Enter Selection, q to quit: b

The utility ends and the device node path is loaded into a text buffer.

4. Make an alias for the device node path. For example:

ok nvalias newconsoledisplay (Ctrl + Y)

Type a space, then hold down the Control key and press the Y key.

5. Configure the output-device parameter for the new console display. For
example:

ok setenv output-device newconsoledisplay

11-40 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 6. Reset the OpenBoot PROM:

ok reset-all

The system now uses the Sun XVR-1200 graphics accelerator as the new console
display.

Note – The default console display, the first graphics accelerator found in probe
order, is still aliased to screen. If you wish to check the new console display, type:
test newconsoledisplay.

FIGURE 15-8 Reconnecting the Keyboard, Mouse, Monitor, and Network

2. Reconnect any other external peripherals.

15.5.2 Choosing the Boot Mode

When the workstation is powered up, the initial action is the boot sequence. Booting
a system is the process for reading the Solaris kernel into system memory and
starting it running.

15-8 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 There are several methods for booting the workstation.
■ Booting from the hard drive
This is the default when an operating environment (system) disk is not in the
DVD-ROM drive.
■ Booting from DVD-ROM
Default when an operating environment (system) disk is in the DVD-ROM drive.
■ Booting in single user mode
Occurs when an init1 option was specified during the power-down sequence.
■ Booting in multi user mode
Default mode when the workstation was shutdown gracefully.

1. Select the boot source:

■ If from a DVD-ROM, insert an operating environment (system) disk in the DVD-
ROM drive.
■ If from the hard disk, ensure there is no operating system disk in the DVD-ROM
drive.

2. Press and release the Power button.

The Power button is located on the front cover of the workstation. Press the Power
button until you hear the internal fans or the hard drive in motion.
The system proceeds with its power on sequence until the operating system shell
displays or the CDE environment is started, as specified in the init default files.

FIGURE 15-9 Powering Up the Workstation

Chapter 15 Finishing Component Replacement 15-9

15.6 Verifying an Installation
You can verify the functionality of the component you replaced or installed using the
following procedure.

1. Power on the system.

See Section 15.5, “Powering On the Workstation” on page 15-7.

2. Follow the power-on flowchart procedures.

See “Basic Troubleshooting” on page 1.

3. Monitor the boot messages.

The OpenBoot PROM houses a mini operating system in which POST and OpenBoot
PROM firmware instructions reside. OpenBoot PROM must complete successfully
before OpenBoot Diagnostics can operate.
If any warning messages are found, see the troubleshooting chapters, “Basic
Troubleshooting” on page 1, “Troubleshooting Flowcharts” on page 1, and
“Introduction to Advanced Troubleshooting” on page 1, for information on
interpreting messages and possible corrective action.

4. If you are uncertain that the problem has been resolved, see “Troubleshooting
Flowcharts” on page 4-1, or consider these alternatives:
■ Configure the NVRAM to enable the Power-On Self-Test (POST).
See “Maximum, Minimum, and Menu Levels of POST” on page 7 for information
on POST output and interpreting the response. This might require rebooting the
workstation.
■ Run selected OpenBoot Diagnostics tests.
See “OpenBoot PROM Utilities” on page 1 for information on availability and
implementation of tests.
■ Run the SunVTS software.
See ““Installing SunVTS” on page 1 for information on running the SunVTS
software and interpreting the results.

Functional Description

This appendix provides a functional description of the hardware architecture for the
Sun Blade 2500 workstation. This functional description covers the following topics:
■ Section C.1, “Hardware Architecture” on page C-1
■ Section C.2, “Motherboard” on page C-4

C.1 Hardware Architecture

C.1.1 System Overview

The Sun Blade 2500 is a dual processor desktop workstation that uses the
UltraSPARC IIIi CPU. The UltraSPARC IIIi uses its distributed shared-memory
multiprocessor architecture with both CPUs installed on a single motherboard. See
FIGURE C-1 for a graphic description of the hardware architecture used in the Sun
Blade 2500 workstation.

C-1
 The memory controller is physically part of each UltraSPARC IIIi processor. That is,
it is on the chip. Both CPUs have their own local physical address space.

The I/O subsystem is designed around two IO-bridge ASICs that bridge between
the system JBus and the PCI buses. Each IO-bridge has two PCI leaves. The master
IO-bridge0 supports two PCI buses: 33 MHz on the PCI-A leaf and 66 MHz on the
PCI-B leaf. The slave IO-bridge1 supports two 66 MHz PCI buses out of PCI-A leaf
and PCI-B leaf.

The leaf for the master IO-bridge0, PCI-2A, connects to the Southbridge. The
Southbridge interfaces with IDE (ATA-100), USB, audio module, XBus, and Super
I/O functions (for example, serial port, parallel port). The PCI-2A leaf is also part of
the boot path. The boot path is:
■ CPU
■ JBus
■ Master IO-bridge0
■ PCI-2A leaf
■ Southbridge
■ XBus
■ Flash PROM

The XBus off the Southbridge is used as an interface to the I2C controller and bus.

A single G-bit Ethernet controller is connected to the PCI-A leaf of IO-bridge1 and
the SCSI controller is connected to the PCI-B leaf of IO-bridge1.

Subsystem
The Sun Blade 2500 workstation supports two CPUs and up to eight Double Data
Rate (DDR) memory DIMMs. Each CPU is connected through a JBus (FIGURE C-1).

C-6 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
C.3.1 UltraSPARC IIIi CPU
The UltraSPARC IIIi processor is a high-performance, highly integrated superscalar
processor implementing the 64-bit SPARC V9 RISC architecture. It is capable of
sustaining the execution of up to four instructions for each cycle, even in the
presence of conditional branches and cache misses. Instructions to multiple
functional units are issued in program order and executed in parallel. In order to
further increase the number of instructions executed for each cycle, instructions from
two basic blocks can be issued in the same group.

The UltraSPARC IIIi CPU supports full implementation of the 64-bit SPARC V9
architecture. It supports a 64-bit virtual address space and a 43-bit physical address
space. The core instruction set has been extended to include graphics instructions
that provide the most common operations used for two-dimensional image
processing, two- and three-dimensional graphics, image compression algorithms,
and parallel operations on pixel data with 8- and 16-bit components.

C.3.1.3 UltraSPARC IIIi Memory Controller
The memory system consists of the memory control unit (MCU) in the CPU and two
physical banks (1A/1B and 2A/2B) of DDR-1 SDRAM memory (FIGURE C-4). Only
registered DIMMS are supported.

Note – At the time of product development the physical banks were labeled 1A/1B
and 2A/2B. This has changed see “OpenBoot PROM Memory Message” on page 11.

Clock buffering with a PLL is provided on the DIMMs. Each physical bank consists
of two 72-bit DDR-1 SDRAM DIMMs. Both banks share a 16-byte data bus plus ECC
data bus. All DIMMs have shared address/control bus. Since each DIMM could be
dual sided (upper and lower banks), there are maximum of four data loads for each
physical bank. Both banks are controlled by the memory controller.

Note – DIMMs must always be loaded in pairs. See Section 11.1.3, “Installing the
DIMMs” on page 11-7 for detailed DIMM installation information.

A memory controller pipelines requests, making use of 16 memory banks when fully
loaded.

The key features of the memory controller are:

■ Maximum SDRAM clock frequency of 133 MHz
■ DDR-1 (Double Data Rate)
■ Supports single bank or dual bank SDRAM DIMMs
■ Memory controller supports two physical banks of 128 bits of data plus 9 bits of
error checking correction (see “ECC Checking and Generation” on page 11)
■ Supports 256 MB, 512 MB and 1 GB DDR-1 SDRAMs, x 4 or x 8 concurrently
■ Supports four SDRAM DIMM slots
■ Supports four internal SDRAM device banks
■ Maximum memory capacity is as follows:
■ 4 GB, using four banks of 512 MB (64 MB x 8) or stacked 256 MB (64 MB x 4)
■ 8 GB using four banks of 1 GB (128 MB x 8) or stacked 512 MB (128 MB x 4)
■ 16 GB using four banks of stacked 1 GB (256 MB x 4)
■ Supported memory space from 256 MB to 16 GB for each memory controller
■ Peak memory bandwidth of 4.2 GB per second @ 133 MHz
■ Three interleaving modes:
■ Rank interleaving
■ Bank interleaving
■ DIMM-to-DIMM interleaving
■ SSTL_2 inputs and outputs

UltraSPARC IIIi Clock

The system clock generator chip generates a 3.3V LVPECL differential clock that is
converted to 1.5V HSTL-levels before being sent to the CPU. An AC coupling circuit
in conjunction with a bias voltage is used to effect the level shifting.

C-10 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
ECC Checking and Generation
All memory transfers have error checking and correction (ECC). The UltraSPARC IIIi
memory controller unit performs ECC generation and checking.

The UltraSPARC IIIi uses the same ECC logic as the UltraSPARC-III. A 9-bit
syndrome is generated using the Hsiaos algorithm for each 128 bits of data. This 9-
bit syndrome enables single-bit error correction and multiple-bit error detection. The
memory controller generates the ECC bits based on the modified Hsiaos algorithm
and writes it out to memory along with the 128 bits of data. When data is read from
memory, the data and ECC bits generate the syndrome bits to indicate the
correctness of the data. A syndrome value of 0 means no errors. A syndrome value
of non-zero indicates single- or multiple-bit errors. If the data is for a foreign
request, the uncorrectable error and correctable error information is sent along with
it on the J_ADTYPE bus.

Core Power Regulators

The Sun Blade 2500 system uses two core voltage regulators, one for each CPU. Each
core voltage regulator has the following requirements:
■ Programmable output voltage from 0.80V to 1.550V through VID bits
■ 12V input source
■ Input voltage tolerance of ±5%
■ Maximum output current of 40A @ 1.3V
■ Output voltage tolerance of ±3%
■ 85% efficiency at full load

The voltage sense line is connected directly from the sense pin of the CPU.

The voltage for each regulator can be set either by a jumper or through software. The
table below shows the VRM voltage ID codes for each core regulator (FIGURE C-5)
and (FIGURE C-6).

Note – Voltage must be set to 1.4V for normal operation.

C.3.2 Memory Subsystem

C.3.2.1 DDR Memory

The Sun Blade 2500 workstation supports two CPUs and up to eight memory
DIMMs. Each CPU is connected through a JBus. Each CPU interfaces directly to
memory (FIGURE C-7). The CPU/memory subsystem consists of the following
functions:
■ UltraSPARC IIIi CPU
■ Four 184-pin DIMMs
■ Voltage regulators for core voltage, memory voltage (common for all memory),
DDR termination voltage, and DTL voltage (common for both CPUs)

C.3.2.2 DDR Memory Block Diagram

C.3.2.3 Memory Architecture

The memory controller unit (MCU) is embedded within the UltraSPARC IIIi
processor. All address, clock, and control signals originate from the processor. These
signals are then transferred to DRAMs on the DIMMs. The data path is 144 bits (2 x
72 bits) wide. Data is directly driven to and from the processor pins.

To minimize latency, the memory controller is integrated on the same chip as the
processor. In a single-processor environment, this allows immediate access on a
cache miss, without having to forward the address over the JBus interconnect.

TABLE C-3 describes the interface between the UltraSPARC IIIi memory controller
unit (MCU) and the DIMMs.

 Memory DIMMs

DIMMs must be loaded in pairs. Each CPU supports four DIMMs (TABLE C-4). The
minimum number of DIMMs required for proper system operation is two. This is
true for single- and dual-CPU configurations. The system operates properly if
memory is only loaded on one of the CPU’s two banks and the second CPU’s
memory banks are left empty. However, for better system performance, each CPU
should have its own local memory. That is, DIMMs should be loaded on both CPUs.

C.3.2.7 Memory Interleaving
The UltraSPARC IIIi supports four interleaving modes:
■ Bank interleaving
■ Rank interleaving
■ DIMM interleaving
■ XOR interleaving

Bank Interleaving
Bank interleaving is interleaving within a single device on a DDR1 SDRAM DIMM.
Each DDR1 SDRAM DIMM used by the workstation contains 18 devices
(FIGURE C-9). For example, bank interleaving can occur between devices 1 and 2 or
devices 17 and 18.

Device 2

Device 17

FIGURE C-9 Bank Interleaving

Note – In this example, 18 memory devices are illustrated. DDR1 SDRAMs may
contain 9 or 36 memory devices.

Note – Do not confuse bank interleaving with DIMM interleaving. For an

explanation of DIMM interleaving see “DIMM Interleaving” on page 22.

Appendix C Functional Description C-21

 Rank Interleaving
Rank interleaving is interleaving between pairs of memory devices on a single
DIMM. Each DDR SDRAM used in the workstation contains 18 devices, nine on one
half and nine on the other half. To perform rank interleaving, one discrete device on
the left half of the memory module must pair with its adjacent memory module on
the right half of the module (FIGURE C-10). For example, rank interleaving can occur
between device 2 and device 11 or between device 9 and 18.

Rank 1 Rank 2 Rank 3 Rank 4

Device 2 Device 11

Device 9 Device 18

FIGURE C-10 Rank Interleaving

DIMM Interleaving
DIMM interleaving is interleaving between pairs of DIMMs. Interleaving between
DIMMs can occur only if all four DIMMs are the same. If the pairs are different, it is
still possible to interleave external banks (in double bank DIMMs) and internal
banks (FIGURE C-11). For example, DIMM interleaving can occur between DDR1
SDRAM pair 1 and DDR1 SDRAM pair 2.

For maximum interleaving performance, all DDR1 SDRAM DIMMs need to be the
same.

Note – There are no constraints for bank or rank interleaving within the same pair.

TABLE C-7 describes the different interleaving modes supported based on the
memory DIMMs used.

Appendix C Functional Description C-23

 XOR Interleaving
The Sun Blade 2500 also supports a fourth interleaving mode called XOR
interleaving. This interleaving mode is used to distribute L2 cache conflict misses
and L2 cache read/write pairs across more banks. To use XOR interleaving, all
DIMMs in a CPU’s two banks must be identical. XOR interleaving is a special case
not described in TABLE C-7.

Mixing DIMM Types

Within the same pair (1 or 2) DIMMs need to be exactly the same (same density, x4
or x8, single or double). DIMMs in different pairs can be different. For example:
■ pair1 (2 DIMMs): double banks, 512 Mb devices, x4

 Main Memory Power Regulator
DDR memory requires a 2.5V voltage source. This voltage is generated through a
memory regulator providing power to all the memory banks. The following is a
listing of the power requirements for the memory regulator:
■ 12V input source
■ Input voltage tolerance of ±5%
■ 2.5V output
■ Maximum output current of 20A at 2.5V

 JBus Key Features
The following are the key features of the JBus (FIGURE C-12):
■ Simple SMP protocol that is SPARC V9 and Sun4u correct, resulting in high
performance for one to two CPUs
■ 128-bit wide bus
■ Full-duplex shared multidrop bus for up to four loads
■ DTL driver/receiver technology
■ Snoopy MOESI protocol
■ Separate flow-controlled address and data transaction
■ Multiplexed address and data bus
■ Variable snoop return delay using sideband signals (no hard latency or
throughput requirements in the protocols)
■ Distributed arbitration
■ Distributed snoop results stalling for resource management
■ Pushed writes, split transID-based read returns
■ Out-of-order data return for different cache addresses. In-order data return
from single noncacheable port. In-order data return for same cacheable
address. Order determined by address bus order.
■ Out-of-order data return values are according to the address bus order.

Note – Data return implies completion of prior coherency events by the requestor.
This is a minimal requirement.

■ Four transIDs for each device ID

C.4.1.2 DTL Configuration

DTL is a bus interface scheme that allows both point-to-point (2-node), and multi-
drop communication on a common bus. DTL is a low-voltage, high-speed interface
with very high signal integrity.

Two types of configurations are possible in DTL: DTL Scheme-1 and DTL Scheme-2.
On UltraSPARC IIIi and other JBus devices, two signals (down_25 and up_open) are
provided to configure DTL IOs of the devices upon power up (TABLE C-8).

Because the Sun Blade 2500 does not use a boot bus, the JBus needs to be ready for
transactions (the first PROM fetch) as the processor comes out of reset state. The
following table shows the configuration signals for both DTL schemes.

DTL Reference Voltage

DTL reference voltages of 1.125V ±5% are generated on the motherboard from a
discrete divider with 1% tolerance.

Note – There is no current drawn on the reference voltage.

C-28 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 DTL IO Power
All DTL IO power is generated on the system board through a DC-DC regulator and
is delivered to the UltraSPARC IIIi processor. The IO voltage is 1.5V. The regulation
of this regulator is ±3%.

C.4.1.3 JBus performance

The peak bandwidth for JBus is 2.56 GB per second at 200 MHz and is 2.13 GB per
second on the Sun Blade 2500 system since JBus is clocked at up to 167 MHz. JBus
can insert a dead cycle between transaction of 2 different masters however, in a Sun
Blade 2500 system no dead cycles are needed.

C.4.2 IO-Bridge

C.4.3 I/O Subsystem

The I/O subsystem is designed around two IO-bridges and one Southbridge. The
IO-bridge is a bridge between JBus and the PCI buses.

The Southbridge is the bridge between PCI, USB, IDE, XBus, and Super I/O
functions.

C.4.3.1 IO-bridges
The Sun Blade 2500 workstation uses two IO-bridge ASICs as the bridge from JBus
to PCI (FIGURE C-13). One IO-bridge is configured as the master IO-bridge0 (JID[1]=1)
supporting a 33 MHz PCI bus (PCI-A leaf) and a 66MHz PCI bus (PCI-B leaf). The
other IO-bridge is configured as the slave IO-bridge 1 (JID[1]=0) supporting two 66
MHz PCI buses through PCI-A and the PCI-B leaves. The boot path is through the
master IO-bridge0 via the PCI-A leaf. See the following IO-bridge block diagram.

C-30 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 IO-bridge is a companion core-logic ASIC to the UltraSPARC IIIi CPU. The IO-
bridge and UltraSPARC IIIi communicate through the JBus. The central task of IO-
bridge is to be the point of access to I/O and perform system interrupts. The main
system interfaces IO-bridge offers are:
■ JBus
■ 66 MHz/64 bit or 33 Mhz/64 bit v2.2 PCI, capable of supporting up to eight
external masters with internal arbiter.

C.4.3.3 JBus Interface

The JBus interface detects transactions present on the JBus that are targeted for the
IO-bridges. The interface accepts and queues those transactions and coordinates
with the destination unit within the IO-bridge.

C.4.3.4 PCI-A Leaf

The PCI-A leaf on IO-bridge0 is a 64 bit/66 MHz or 64-bit/33 MHz PCI version 2.2
compliant implementation. The interface has an internal arbiter that can support up
to eight masters resident on the bus. Support for external arbitration is also present.

Note – This interface on the IO-bridge is PCI v2.2 compliant.

The PCI-A leaf includes an interrupt block that receives system interrupts from the
external IChip2. This PCI leaf also controls interrupts generated from any activity
within the PCI interface unit itself. The interrupt unit communicates with the JBus
cluster to send out interrupts onto the JBus.

C.4.3.5 PCI-B Leaf

The PCI-B interface is a 64 bit/66 MHz PCI leaf with an internal arbiter. An external
arbiter is also supported. This is a fully functional standalone PCI bus.

C.4.3.6 PCI I/O Cache

Each PCI leaf has an I/O cache to improve performance. The PCI I/O cache has
eight entries, each of which contains 64 bytes of data. The I/O cache can also
perform data prefetching to aid in minimizing DMA read latency (IO-bridge is
sending data out to the PCI bus). This prefetching can be disabled by software
through configuration space registers (CSR). In addition, the entire cache can be
bypassed or disabled effectively by software.

Appendix C Functional Description C-31

C.4.3.7 PCI Configuration and I/O Space
The PCI configuration and I/O space correspond to those defined by the PCI Local
Bus Specification Revision 2.2.

The PCI specification defines the configuration space for software initialization and
configuration of PCI devices. This space is limited to a maximum size of 16 MB for
each device. As accesses in this space generate specific PCI transactions called
“configuration cycles”, the PCI configuration spaces are decoded by the IO-bridge.

The PCI specification also defines a 32-bit I/O space for each device. The I/O space
is accessed through dedicated transactions. The PCI specification recommends
devices be mapped in the memory space and not in the I/O space. The I/O space is
provided to support devices that are noncompliant with the intent of the PCI
specification. Providing a full 32-bit space for each device is very costly, as such Sun
Blade 2500 systems (through IO-bridge) support only 16 MB of I/O space for each
device.

The PCI configuration and I/O space in UltraSPARC IIIi-based systems are
geographically partitioned through a software/firmware convention in which 32 MB
of space is reserved for each PCI bus in the system. These 32 MB correspond to 16
MB (lower) for the PCI configuration space and 16 MB (upper) for the PCI I/O
space.

C.4.4 Multiple Graphic Accelerators Installed in a

Single Workstation
A single Sun Blade 2500 system can support multiple Sun XVR-100, Sun XVR-500,
Sun XVR-600, and Sun XVR-1200 graphics accelerators. The PCI bus that these
accelerators share can be reconfigured to allow the probe order of each console
device to be changed. For additional information about multiple graphic accelerators
installed in a single workstation See Section 11.5.5, “Special Considerations for
Multiple Graphic Accelerators Installed in a Single Workstation” on page 11-38.

C.4.5 XBus

C.4.5.1 PCI-ISA bridge

The ISA bus is an I/O bus that runs at 8 MHz. The Sun Blade 2500 system uses only
a subset of this bus called the XBus.

C-32 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
C.4.5.2 Flash PROM
The Sun Blade 2500 motherboard contains 1 MB of flash memory connected to the
XBus of the Southbridge ASIC. The flash PROM has an 8 Mbit, 5.0V flash memory.

The 1 MB of the PROM memory is divided into two halves, the OBP and the power-
on self-test (POST). The OBP and POST image are in a separate address space off of
the XBus space.

C.5 System Clocks and Interrupt Processing

C.5.1 IChip2
The Sun Blade 2500 system uses the IChip2 as the interrupt concentrator. The
IChip2:
■ Processes all 11 major groups of the interrupts comprising a total of 48 different
interrupt signals at the same time. The result of processing is a 6-bit code
designating the source of the interrupt and its group.
■ Supports all three types of interrupts: level high, level low, and pulse low.
■ Provides equal priority to all interrupting devices. When two devices need
servicing at the same time, the IChip2 prioritizes based on the round-robin
scheduling scheme.
■ Generates two groups of PCI clocks, Group A and Group B, from a 133 MHz
crystal oscillator in PECL form.

Note – The clock-generation feature of the IChip 2 is not utilized in the Sun Blade
2500 system.

C.5.1.1 PCI Clocks

The PCI clocks are driven by an off-the-shelf PC-style clock generator. The Sun Blade
2500 system turns off the clock to Energy Star capable slots. This is accomplished by

Appendix C Functional Description C-43

 The Sun Blade 2500 system monitors six temperatures:
■ UltraSPARC IIIi 0 (internal in CPU)
■ UltraSPARC IIIi 1 (internal in CPU)
■ Motherboard (MB) temp sense 1
■ Motherboard (MB) temp sense 2
■ Ambient (monitored internally in the ASIC HW Monitor 1)
■ Ambient (monitored internally in the ASIC HW Monitor 2)

All six temperature readings can be read through PICL software.

The Sun Blade 2500 workstation supports four system fans (two fans for CPU0 and
CPU1 and two fans for the system). The speed of the four fans is controlled by the
PWM outputs of the two ASICs. All four fans are controlled individually. The ASIC
controls fan speed according to temperature without intervention from the host
processor.

Fan Blast
During OBP boot and before the ADM drivers are loaded, the fans are turned on to
their maximum speed by using the fan blast function.

After the ADMs are initialized and the automatic fan speed control bit is set, fan
speed control is handed over to the hardware monitors and the Fan Blast bit is
cleared to 0.

Fan Speed Monitoring

The Sun Blade 2500 system can monitor the speed of the four system fans through
the Tach inputs. These inputs are driven by the Fan Tach outputs of the fan.

Thermal Shutdown
If the temperature exceeds the temperature high limit, the ADM generates an over-
temperature interrupt (INT/ALERT) to cause the software to turn off the system. If
the temperature exceeds the temperature THERM limit, the ADM generates an
emergency off (THERM output) to turn off the power supply without software
intervention.

APPENDIX D

Power Management

This chapter discusses power management. Topics include:

■ Section D.1, “Enabling Power Management” on page D-2
■ Section D.2, “Disabling Power Management” on page D-5

To help conserve energy, the Sun Blade 2500 workstation has power management
features that are configured using the Dtpower application. The Dtpower application
reads and writes its configuration to the /etc/power.conf file. You can configure
power management by editing the power.conf file, however, use of the Dtpower
application is much easier.

Note – If you have configured the Solaris operating environment and answered that
you did not want to use power management, the Dtpower application will produce
errors during system configuration until power management is enabled.

Dtpower has two preconfigured power management modes: minimal and standard.
There is also a customizable and disabled mode. The following table provides
information about the different modes.

TABLE D-1 Dtpower Power Management Modes

Mode Power Management

Minimal By default, only displays (monitors) go into low-power mode after

30 minutes of idle time (auto shutdown is not automatically
enabled).

D-1
 TABLE D-1 Dtpower Power Management Modes

Mode Power Management

Standard By default, displays (monitors) go into low-power mode and the

system shuts down after 30 minutes idle time (auto shutdown is
automatically enabled).
Customized Displays are configured: 15 min, 30 min, 1 hr, 2 hr, or Always On.
Disks are configured: 15 min, 30 min, 1 hr, 2 hr, or Always On.
Autoshutdown is configured: 15 min, 30 min, 45 min, 1 hr, 2 hr, 3 hr,
4 hr, 6 hr, or 0 hr at any time.
Disabled No workstation power management.

Before configuring power management, consider the role that the Sun Blade 2500
workstation will perform:
■ Is it acting as a server? If so, use only minimal power management or none at all.
■ Is it used as a remote host for after hours work? If so, consider the autoshutdown
times.
■ Is it used in a multiple user environment? If so, weigh the idle time against the
expected demand.

D.1 Enabling Power Management

1. At the system prompt type:

% /usr/dt/bin/dtpower

Note – The popup message, “Scheme Override Confirmation” maybe displayed if

system power management for your workstation was edited by means other than
this Dtpower procedure. If this occurs, answer the questions in the popup menu and
then perform steps 2-6 of the following procedure.

The Dtpower window is displayed on your screen.

D-2 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
2. From the Current Power Saving Scheme pull-down menu, select “Customized”,
Minimal, or Standard.
■ If you selected Minimal or Standard, click OK.
The application exits and you have enabled power management.
■ If you selected “Customized” or would like to customize a minimal or standard
mode, click More.
The window expands. Continue with the remaining steps.

3. Select the Device Idle Time Before Power Saving Starts time.
Selecting “15 Min” means that after 15 minutes of inactivity, both the display and the
disks go to a low-power mode. “Always On” disables power management.

4. Determine if you want to override the idle time for displays or disks and for what
idle time.
For example, you might want the display to go to low-power mode after 15 minutes,
the hard disk after 30 minutes, and the entire system after an hour.

a. Set the system Device Idle Time Before Power Saving Starts time to 1 hour.

b. Select Displays and set the Override Device Idle Time to 15 minutes.

c. Select Disks and set the Override Device Idle Time to 30 minutes.

Note – The value of the Override Device Idle time takes precedence over the value
of the system Device Idle Time. For example, if the Override Device Idle Time for the
displays is set to 2 hours and the system Device Idle time is set to 1 hour the
displays will not go into power saving mode for 2 hours.

5. Determine if you want to use autoshutdown and for what times of day.
For example, if the system is idle for more than 15 minutes between the hours of 8:00
pm and 7:00 am, you want the system to shut down completely.

a. Select Autoshutdown Enabled and click Edit.

The Dtpower (autoshutdown) window is displayed.

b. Type the starting (8:00 pm) and ending (7:00 am) times into the fields provided.

c. If you want the system to automatically start at the ending time, select the
Restart button.
For example, the system will be up and ready for use at 7:02 am before the user
arrives.

Appendix D Power Management D-3

 Note – The time following the Restart at text is dynamic and updates to the ending
time after clicking the OK button.

d. Set the Shutdown During This Interval If Idle For time to 15 minutes.

e. Click OK.

6. Click OK to close the application.

D.1.1 Scenarios for the Example Configuration

Use TABLE D-2 and TABLE D-3 to help clarify the behavior of power management by
providing a timeline for two scenarios. For these situations, the previously described
example configuration is used. The first scenario describes what happens when the
user leaves for lunch.

TABLE D-2 First Scenario Timeline

Time Event

11:55 am User is typing at keyboard.

11:59 am User leaves to go to lunch.
12:14 pm Display goes to low-power mode.
12:29 pm Disk goes to low-power mode.
12:59 pm Entire system goes to low-power mode.
1:01 pm User returns from lunch and taps keyboard to bring system, disk,
and display to a normal state.

The second scenario describes what happens when the user leaves for the day and
signs on from home.

TABLE D-3 Second Scenario Timeline

Time Event

4:25 pm User logs out and leaves to go home.

4:40 pm Display goes to low-power mode.
4:55 pm Disk goes to low-power mode.
5:20 pm User logs in remotely. Disk and display return to a normal state.
7:53 pm User logs out.
8:00 pm Autoshutdown enabled.

D-4 Sun Blade 2500 Service, Diagnostics, and Troubleshooting Manual • April 2004
 TABLE D-3 Second Scenario Timeline (Continued)

Time Event

8:08 pm Display goes to low-power mode.

8:15 pm System shuts down.
7:00 am Autoshutdown disabled, system restarts.

D.1.2 Activating the Workstation From Low-Power

Mode
The simplest way to reactivate the Sun Blade 2500 workstation from low-power
mode is to tap the spacebar on the keyboard. Additionally, moving the mouse can
also bring the system out of low-power mode.

D.2 Disabling Power Management

This section describes how to disable hard drive and system power management.

D.2.1 Disabling Hard Drive Power Management

When the system goes to low-power mode, the hard drive spins down to conserve
power. Later, when you perform a task that accesses the hard drive, the hard drive
spins up. You might have to wait a few seconds for the hard drive to reach full
speed. If this delay is inconvenient, you can turn off hard drive power management,
which prevents the hard drive from entering the low-power mode.

1. As superuser, edit the /etc/power.conf file to include the following line:

device-thresholds /dev/dsk/c0t0d0s0 always-on

2. To initialize power management, type:

# /usr/sbin/pmconfig

Appendix D Power Management D-5

 This procedure configures the power management framework to keep the hard drive
spinning all of the time, regardless of system usage. To completely turn off all
power-saving features of the Sun Blade 2500 workstation, use the procedure in
“Disabling All System Power Management” on page 6.

D.2.2 Disabling All System Power Management

You can disable the power management feature by using the Dtpower application.

1. At the system prompt type:

% /usr/dt/bin/dtpower

The Dtpower window is displayed on your screen.

2. From the Current Power Saving Scheme pull-down menu, select Disabled.

3. Click OK.
The application closes and power management is disabled. The display and disk
stay in normal-power mode and autoshutdown is disabled.
