Metro Ethernet Routing Switch 8600 pre-E, E, and M modules

feature set
Each Metro Ethernet Routing Switch 8600 pre-E, E, or M module consists
of a Backplane Forwarding Module (BFM) with common application
specific integrated circuits (ASIC) on each module. These ASICs provide a
forwarding engine and local storage of Layer 2 to 4 forwarding tables. Each
forwarding engine provides lookups, resolves addresses and sends packets
through the switch fabric to a destination port without CPU intervention. The
forwarding engine also filters packets against current prioritization policies
and can set prioritization information in the internal packet header.
The BFM is also equipped with eight priority queues per port. You can use
either of the following two prioritization schemes:
• Strict priority
• Weighted Round Robin (WRR)

Strict priority guarantees the highest priority. WRR gives priority based on a
round robin algorithm. For more information about prioritization schemes
see Network Design Guidelines (313197-E).

Output buffer memory consists of 8 MB of memory allocated to each Gigabit

Ethernet port or shared among eight 10/100 ports.

Note that Metro Ethernet Routing Switch 8600 does not support pre-E
modules.

Metro Ethernet Routing Switch 8600 R module feature set

Each Metro Ethernet Routing Switch 8600 R module (Release 4.0 and
later) consists of a Distributed Processing Module (DPM) as well as a Port
Interface Module (PIM). The PIM consists of various Media Access Controls

(MAC) and Physical Layer Controls (PHY) as well as the physical interfaces
for direct network connections. A single PIM interconnects with a single
DPM to form a Metro Ethernet Routing Switch 8600 Module. Modules with
DPMs are R modules.
Metro Ethernet Routing Switch 8600 modules that use the BFM are pre-E,
E, or M modules. These modules are described in "Metro Ethernet Routing
Switch 8600 pre-E, E, and M modules feature set" (page 21).
Each DPM contains either two or three lanes, depending on the module.
Both the 8630GBR and the 8683XLR modules consist of three lanes. The
8648GTR module consists of two lanes. Each lane is also known as a
Flexible Forwarding Engine (FFE). The FFE lane is the basis for the Metro
Ethernet Routing Switch 8600 R modules. The FFE lane consists of:
• Two Flexible Route Switch Processors—ingress Route Switch Processor
2 (RSP2) and egress RSP2
• One egress packet handling ASIC–F2E
• One ingress packet handling ASIC–F2I

"Metro Ethernet Routing Switch 8600 R module packet flow on ingress and
egress" (page 22) shows the Metro Ethernet Routing Switch 8600 R module
packet flow on ingress and egress.
Metro Ethernet Routing Switch 8600 R module packet flow on ingress and
egress

The ingress RSP2 performs lookups, filtering and classification operations,

and modifies the IP and MAC headers within the body of the packet to
reflect routing and switching decisions.

 M mode configuration requirements 23

The RSP2 determines the information the fabric needs to carry the packet
to the correct egress point and determines the physical egress port. As part
of the lookup process, the RSP2 may also determine and record the egress
queue ID and pass it to the egress RSP2.
Encapsulation is the most significant operation that the egress RSP2
performs. To specify the egress queue, the queuing and traffic shaping
functions use:
• encapsulation information from the egress RSP2
• MAC and IP packet headers
• Quality of Service (QoS) bits

The F2E egress ASIC supports the FFE QoS, including the functions
of random early drop, queuing and selection, traffic shaping, and
communicating to other similar R modules. Similarly, the F2I ingress ASIC
provides packet policing and marking.
Each DPM also consists of the following:
• One Fast TAPmux (FTAP) interface to the Metro Ethernet Routing
Switch 8600 Switch Fabric Modules
• One Feedback Output Queue Manager (FOQ) Field-Programmable
Gate Array (FPGA)

The FTAP ASIC connects each DPM to the CPU/Switch Fabric modules
through the Metro Ethernet Routing Switch 8600 switching backplane.

The FOQ Management system collects information about the state of

queues, packet storage elements, and the fabric. This information is
available to the F2I at the point at which packets are segmented for entry
to the fabric. When congestion exists, Metro Ethernet Routing Switch
8600 modules with a BFM (pre-E, E, and M modules) use fabric feedback
information only at this point to drop packets.

The FOQ mechanism also provides information about the state of each
of the egress queues and on the fullness of the F2E reassembly function
buffers and queues. The F2E reports this information to the FOQ Manager
FPGA on each module. The constellation of these FOQ FPGAs (one per
DPM) drives a shared backplane bus that each FPGA senses. Therefore,
each R module has pertinent information about the state of all other R
modules in the system.

M mode configuration requirements

M mode supports the Metro Ethernet Routing Switch 8600 M module feature
set. Full support of M mode requires the following configuration conditions:
• The chassis must include at least one 8691omSF CPU module.

 24 Metro Ethernet Routing Switch 8600 modules

• All modules installed in the chassis must minimally support 128 000
table entries. M modules (8632TXM, 8648TXM, 8608GBM, 8608GTM,
8683POSM, 8672ATME, 8672ATMM, 8681XLR, and 8681XLW
modules) support 128 000 table entries.
• M mode must be enabled.
If you enable M mode and one or more of the modules installed in the
chassis is an E module (32 000 table entries), the E modules become
disabled. This protects the system forwarding tables from losing entries.
For information about enabling or disabling M mode, see Managing
Platform Operations (315545-E).

If your system has M modules, E modules, or pre-E modules, see Managing

Platform Operations (315545-E) for information about how to configure the
switch to boot in the desired mode.

R mode configuration requirements

R mode supports the Metro Ethernet Routing Switch 8600 R module feature
set. Full support of R mode requires the following configuration conditions:
• The system must include only R modules. You can have a system with a
mix of R, M, E, or pre-E modules configured in R mode. However, the M,
E, or pre-E modules are not enabled. For information about configuring
R modules in R mode, see Managing Platform Operations (315545-E).
• The system must include at least one 8692omSF CPU module.
R modules do not boot with the 8691omSF CPU module.
• R modules require Metro Ethernet Routing Switch 8600 Release 4.0
or later.
• R mode must be enabled. For information about enabling R mode, see
Managing Platform Operations (315545-E).
If the system is currently in default mode or M mode with CPU/SF 1 as
the master and CPU/SF 2 as the standby, and you enable R mode on
CPU/SF 1, save the configuration and reboot, CPU/SF 2 comes up as
the master and CPU/SF 1 as the standby. If you then enable R mode
on the new master (CPU/SF 2), the standby (CPU/SF 1) goes offline
and remains offline.

For information about how to configure QoS, Filters, Policing, and Shaping
on R modules, see Nortel Metro Ethernet Routing Switch 8600 Configuration
— QoS and Traffic Filters (NN46220-508).

ESM 8668 Metro Ethernet Services Module

The ESM 8668 Metro Ethernet Services Module (Metro ESM 8668) provides
eight 1000Base SFP Gigabit Ethernet ports. The Metro ESM 8668 has the
same architecture as the Metro Ethernet Routing Switch 8600 interface
modules, but also contains an additional network processor in the data path
of each of the eight Ethernet ports.
The heart of the ESM 8668 is the flexible network processor. The network
processor contains four packet processing engines, each running at 400
megahertz (MHz). This architecture provides the flexibility, memory and
processing power to:
• Implement a highly scalable and feature rich Ethernet VPN solution.
• Enable the highly resilient 50 millisecond (ms) Gigabit Ethernet access
ring solution with the Ethernet Services Unit (ESU) 18x0 product family.
• Allow future feature enhancements through software upgrades.

The 8691SF/256 (DS1404090) is functionally identical to the 8691SF except

it has 256 MB of synchronous dynamic random access memory (SDRAM)
installed. The 8691SF/256 is identified by the front panel model number
label in the upper right corner as 8691SF/256.

You can use the 8691SF as a Metro Ethernet switch fabric with the
appropriate memory upgrade. See Installing a CPU Memory Upgrade
(314832-D) for instructions for upgrading CPU memory.

The 8691omSF module consists of a printed circuit board with status LEDs,
a management port, a DCE/DTE switch for the console port, a console port,
a modem port, a reset button, and a PC Card slot.

The CPU subsystem uses a PowerPC CPU and has 256 MB of SDRAM.
The 8691omSF module contains 16 MB of onboard flash memory used to
store the image file, and 2 MB of boot memory (ROM).

The routing switch fabric uses 10 MB of shared, high-speed memory. This

memory buffers traffic destined for I/O modules. The switch logic allocates
memory to the various switch priority queues according to traffic usage and
current switch configuration.

In all 8000 series chassis other than the 8003 chassis, you can install a
8691omSF module in both slots 5 and 6 of the chassis to enable redundant
operation. The redundant module in slot 6 can assume the processing
duties of a failing primary 8691omSF module in slot 5.

When the 8691omSF module in slot 6 completes initialization, it relearns the

routing and VLAN bridging information for the switch unless the HA-CPU
flag is enabled. If HA-CPU is enabled, the static routes and ARP entries
for routing are synchronized to the redundant CPU, which results in no
interruption of network services.

The two 8691omSF modules share switch fabric functions for the switch. If
one 8691omSF module fails, the system reverts to operation with a single
8691omSF module.

Note that when the Metro ESM 8668 module is installed, the HA-CPU flag
is not supported.

The Switch LEDs and the CPU LEDs serve as a bar graph to indicate card
activity. The Switch bar graph increases as the switch fabric utilization
increases. The CPU bar graph increases when the CPU is actively
performing tasks, such as learning media access control (MAC) addresses,
updating routing tables, or interacting with the device management station.

Note that you use this port only as a management port. This port provides
out-of-band management for the 8691omSF module.

DCE/DTE switch
The DCE/DTE switch changes the pin assignments on the Console port.
Use this switch to designate the connector as either DTE or DCE. For
information about pin assignments for the Console port, see "Console serial
port" (page 130).

Serial ports
The 8691omSF module provides two serial ports for attaching modem and
console devices. You can use the console port to access the 8691omSF
module with a terminal using the CLI. Use the modem port to connect a
standard modem for out-of-band, dial-up management. For information
about pin assignments for these ports, see "Console serial port" (page
130) and "Modem serial port" (page 130).

Reset button
Use the recessed Reset button on the module to perform a hard reset or
reboot of the system.

PC Card slot
The PC Card slot in the 8691omSF module accepts an ATA-type,
SanDisk-compatible flash memory card. This memory card provides a
convenient way to store switch configurations and boot images. Using a
memory card, you can quickly transfer configurations and images between
switches or store multiple configurations for a single switch.
Supported memory cards for the 8691omSF module include the following:
• Modem cards that are compatible with Intel 8250 or National 16552
serial ports
• LAN cards from 3COM 589, 562, or 556 equipment.

8692omSF module
Dual 8692omSF switch fabric modules ("8692omSF module" (page 68))
enable a maximum switch bandwidth of 512 Gb/s. Using the Split MultiLink
Trunking (SMLT) protocol in the core, a redundant Metro Ethernet Routing
Switch 8600 with two 8692omSF modules can provide over 1 terabit per
second (Tb/s) of core switching capacity.

8692omSF module

Do not use any software prior to Metro Ethernet Routing Switch 8600
Release 3.6 with the 8692omSF CPU module. For more information, see
Nortel Metro Ethernet Routing Switch 8600 Important Notice — Using the
Correct Software Version for the 8692SF CPU Module (NN46220-404).

The 8692SF module is equivalent to the 8692omSF module. It can be used

as Metro Ethernet switch fabric with the appropriate software. See Nortel
Metro Ethernet Routing Switch 8600 Important Notice — Using the Correct
Software Version for the 8692SF CPU Module (NN46220-404).

The 8692omSF module uses a CPU similar to the PowerPC CPU of the
8691omSF. The 8692omSF CPU has 256 MB of synchronous dynamic
random access memory (SDRAM) for forwarding tables, and 56 MB of
onboard flash memory for configuration, image and log file storage.

The 8692omSF is capable of supporting an optional Metro Ethernet

enhanced CPU daughter card. The Metro Ethernet enhanced CPU
daughter card is a mezzanine daughter card consisting of dual 1 GHz
PowerPC processors. Installing the daughter card on an 8692omSF module
offloads processor intensive tasks from the 333 MHz processor located on
the 8692omSF CPU motherboard. The Metro Ethernet enhanced CPU
daughter card is required for Provider Backbone Transport (PBT) services.
For installation instructions, see Appendix "Installing the Metro Ethernet
enhanced CPU daughter card" (page 135).

The flash memory is divided into two volumes: Volume/0 has a capacity of
16 MB and Volume/1 has a capacity of 40 MB. You can use either volume
to store multiple file types, however, the 8692omSF module can only use
either Volume/0 or Volume/1. By default, the system can only use 16 MB on
Volume/0. If you want to use 40 MB on Volume/1, refer to the procedure
for upgrading the flash memory to 40 MB in Nortel Metro Ethernet Routing
Switch 8600 Upgrading — Software Release 4.1 (NN46220-402).

Using the SMLT protocol in the core, the Metro Ethernet Routing Switch
8600 can provide over 1 Tb/s of core switching capability.

 8692omSF module 69

You can install a 8692omSF module in both slots 5 and 6 of the 8006, 8010,
or 8010co chassis to enable redundant operation. The redundant module in
slot 6 can then assume the processing duties of a failing primary 8692omSF
module in slot 5.

When the 8692omSF module in slot 6 completes initialization, it recalculates

the topology information (Layer 2 including spanning tree groups (STG),
Layer 3 including routing topology using Routing Information Proctocol/Open
Shortest Path First (RIP/OSPF) or Border Gateway Protocol (BGP)) for
the switch unless High Availability mode (HA-CPU flag) is enabled. In
High Availability mode, all Layer 2 information is synchronized to the
redundant CPU, which results in no interruption of network services. For
more information about High Availability mode, see Managing Platform
Operations (315545-E).

The two 8692omSF modules share switch fabric functions for the switch. If
one 8692omSF module fails, the system reverts to operation with a single
8692omSF module.

Installing and replacing a module

This section contains procedures for installing and replacing a module.

You can add or replace a module with the power on or off.

Prerequisites
• The Metro Ethernet Routing Switch 8600 modules are sensitive to static
electricity. Static discharge from your clothing or other fixtures around
you, even at levels that do not create a spark, can cause damage to the
Metro Ethernet Routing Switch 8600 modules.

CAUTION
Electrostatic discharge can damage hardware. Do the
following to protect your equipment from damage.

To prevent static discharge when you work with Metro Ethernet Routing
Switch 8600 modules, place each module on a grounded antistatic mat
until you are ready to install it. If you do not have an antistatic mat, wear
a discharge leash or wrist strap to free yourself of static before you touch
a module. (An antistatic wrist strap is shipped with the 8010co chassis.)
You can also free yourself of static by touching the metal chassis before
you handle the module.

Removing a module
Remove or replace a module in your chassis.

You can remove any Metro Ethernet Routing Switch 8600 module from an
operating switch chassis without turning off the chassis power.

Prerequisites
• Back up your configuration before you remove a 8691omSF or
8692omSF module.

CAUTION
If the chassis has only one 8691omSF or 8692omSF module
and you remove that module, the switch will not operate.

• After you remove or replace a module in your chassis, you can expect
the following results:
— If you remove an interface module from an operating switch without
turning off the chassis power and replace it with the same type
module, the system restores the configuration.

 Installing and replacing a module 77

— To remove a module from an active system, you must disable the

module before you remove it. Disabling the slot before removing the
module provides a clean disconnect from all services.
The following procedure includes directions for disabling the module.
— If you remove an 8672ATME, 8672ATMM, or 8683POSM module
from an operating switch without turning off the chassis power and
the module you insert has the same type MDAs installed as the
module that you removed, the system saves the configuration.
— If you remove an 8672ATME, 8672ATMM, or 8683POSM module
from an operating switch without turning off the chassis power
and the module you insert has different MDAs installed than the
module that you removed, you must reconfigure the module. Nortel
recommends that you save the original configuration in a file for
future use.
— If you replace a module with a different type module, the system
discards the configuration of the old ports and adds the new ports to
either the default VLAN or a null VLAN, depending on the operating
mode of the switch.
— If you save the configuration in nonvolatile random access memory
(NVRAM), turn off the switch, replace a module with a different
module type, and turn the system on again, the system discards
the configuration of the old ports and adds new ports to either the
default VLAN or an unassigned VLAN, depending on the operating
mode of the switch.
— If you replace an 8691omSF or 8692omSF module, all the other
modules in the chassis reset and revert to their saved configuration
settings. If you did not save the configuration settings for a module,
the module reverts to its factory default settings.

Procedure steps

Step Action

1 Connect to the Metro Ethernet Routing Switch 8600 command line

interface (CLI) using the management console port.
2 To disable the slot of the module that you are removing, enter the
following command. Specify the slot number for <slotnum>.
conf slot <slotnum> state disable

3 Confirm that the module is disabled.

The online LED on the front panel module is amber when the I/O

Install a Metro Ethernet Routing Switch 8600 module.

You can install a Metro Ethernet Routing Switch 8600 module with the
power on or off. If you install a module in the same chassis slot where the
same type of module was previously installed, the previous configuration is
maintained for that module in that slot. With the 8672ATME, 8672ATMM,
and 8683POSM modules, the configuration is maintained only if the same
type of MDAs are used. In all other cases, a module installed in an Ethernet
Routing Switch 8000 Series chassis resets to factory defaults.

Make sure you securely tighten all captive screws for proper module
operation. This ensures a good connection between the module
and the backplane and prevents apparent module failure of properly
functioning modules.
If a module failure occurs, check for possible backplane connection
problems as a cause. Make sure the module is correctly seated
in the backplane connector and the captive screws are securely
tightened. If the module still fails to operate, contact Nortel customer
support for assistance.

 86 Installing Metro Ethernet Routing Switch 8600 modules and connecting equipment

Connecting a PC or terminal to the switch

Connect a PC or terminal to the console port to use Device Manager or the
command line interface (CLI) to customize your Metro Ethernet Routing
Switch 8600 configuration (for example, by editing IP parameters). To
establish a local CLI or Device Manager session, you must connect a PC or
a VT-100 terminal to the console port on the CPU module.

Prerequisites
• You need a serial console cable with a 9-pin receptacle connector.

Procedure steps

Step Action

1 Turn on and configure the terminal or a communications port on the

PC using the values in "Procedure job aid: PC and terminal settings"
(page 86).
See the PC or terminal user manual for instructions.

2 Insert the 9-pin receptacle end of the console cable into the console
connector on the CPU module.
3 Attach the 9-pin plug end of the cable to the serial communications
port on the back of the PC or terminal.

 Connecting a modem to the switch 87

If you need remote dial-in access to the CLI, you can connect a modem to
the CPU module using a serial cable.

Prerequisites
• The Metro Ethernet Routing Switch 8600 supports the AT or Hayes
compatible modem.
• You need a DTE-to-DCE cable (straight or transmit cable).
Because the modem port expects to receive Data Set Ready (DSR) and
Clear To Send (CTS) signals before transmitting, these control lines
are required in the cables.

Procedure steps

Step Action

1 Turn on and configure the modem, using the parameters in

"Procedure job aid: Modem settings" (page 87).
See the modem documentation for instructions.

2 Insert the 9-pin receptacle end of the serial cable into the modem

Connecting a network management station to the switch

Connect a network management station to the management port for
out-of-band management of the switch.

The management port on the CPU modules is a 10/100 Mb/s Ethernet port
implemented on an RJ-45 connector wired as an MDI connection. You
can use this port to connect the switch to a network management station
for out-of-band management of the switch using a Web browser or Device
Manager.

The port has its own IP address but does not switch traffic to other ports in
the chassis.

Prerequisites
• To connect ports that will operate at 100 Mb/s, use only Category 5 UTP
cable. For 10 Mb/s connections, you can use Category 3, 4, or 5 copper
unshielded twisted pair (UTP) cable.

Procedure steps

Step Action

1 Insert the UTP cable into the RJ-45 receptacle connector on the
CPU module.

The following sections describe the initialization process for the 8672ATME,
8672ATMM, and 8683POSM modules.

Initializing the 8672ATME and 8672ATMM modules

The CPU module retrieves the image file to download to the 8672ATME or
8672ATMM module. First, the CPU module searches the host flash memory
for the file, then the PC Card. The CPU module downloads the image file to
the 8672ATME, or 8672ATMM and identifies which MDAs are installed. The
screen displays a message similar to the following:
Using image = /slot/p80t3600.dld for ATM card download.
ATM card: Slot 4 MDA [OC-12c MM] [Quad OC-3c MM] Ver=2.2

If the image file is not found in either the flash memory or the PC Card, the
system stops and the screen displays an error message such as:
ERROR Task=rcStart Couldn’t find an ATM download image!
Aborting card initialization in Slot=4

or:
ERROR Task=rcStart portPresent:port=X/X, invalid port Type

The 8672ATME or 8672ATMM module requests a redownload from the

switch fabric module, and the screen displays the following message:
Redownload requested by ATM card in slot <number>.

If the image download is unsuccessful, the screen displays the following

message:

Initializing the 8683POSM module

The CPU module retrieves the image file to download to the 8683POSM
module. First, the CPU module searches the host flash memory for the
file, then the PC Card. The CPU module downloads the image file to the
8683POSM module and identifies which MDAs are installed. The screen
displays a message similar to the following:
Downloading POS image to slot <number> .........Done (file
name and image size.)

If the CPU module does not find the image file in either the flash memory or
the PC Card, the screen displays this message:
POS image file name not found either in FLASH or PCMCIA.

If the downloaded is unsuccessful, the screen displays the following

message:
Card is off line.

The 8683POSM module requests a redownload from the CPU module;

the screen displays this message:
Redownload requested by POS card in slot <number>.

The 8683POSM module attempts a redownload three times. If the download

is still unsuccessful, the 8683POSM module goes offline and the screen
displays this message:
Redownload of POS card in slot <number> failed maximum 3
times; POS card is offline.

When the 8683POSM module boots, the redownload count is reset to 0.

The distances listed in "Gigabit Ethernet minimum distance ranges" (page

106) represent the minimum and maximum distances attainable on high
quality fiber. You may be able to run Gigabit Ethernet significantly farther
assuming that the loss budget is not exceeded, and dispersion is well
controlled. Nortel recommends a fiber loss analysis for each run of cable to
determine actual achievable distances (see "Gigabit Ethernet flux budget
and loss characteristics" (page 107)).

Appendix B
Installing the Metro Ethernet enhanced
CPU daughter card
This appendix describes how to install the optional Metro Ethernet
enhanced CPU daughter card (hereafter referred to as the daughter card or
SuperMezz) on the 8692 Series CPU modules (8692SF and 8692omSF) .

The SuperMezz is a mezzanine daughter card that consists of dual 1 GHz

Power PC processors. Installing the daughter card on an 8692 Series
module offloads processor-intensive tasks from the 333 MHz processor
located on the 8692 CPU.

Prerequisites
• All Metro Ethernet Services Modules (Metro ESM 8668) in your chassis
must have a jumper installed.

CAUTION
Before installing the SuperMezz, all Metro ESM 8668 modules
in your chassis must have a jumper installed. See "Installing
the jumper on an ESM 8668" (page 139) for directions on how
to install the jumper.

• The SuperMezz is only supported on the 8692 Series CPU modules.

• The SuperMezz is required for Provider Backbone Transport (PBT)
services.
• In a system with two 8692SF CPU modules (or two 8692omSF CPU
modules), you must install a SuperMezz on both CPU modules.
• Do the following to protect your equipment from electrostatic discharge.

 136 Appendix B Installing the Metro Ethernet enhanced CPU daughter card

CAUTION
Electrostatic discharge can damage hardware.

The 8692 Series CPU modules are sensitive to static electricity. Be

aware that electrostatic discharge from your clothing or other fixtures
around you, even at levels that do not create a spark, can cause damage
to the module components.
To prevent static discharge:
— Always place each module on a grounded antistatic mat until you
are ready to perform the upgrade or leave the module in the sealed
ESD bag.
— Always wear a static discharge leash or an antistatic wrist strap to
free yourself of electrostatic charges before you touch a module.

Procedure steps
Step Action

1 If you have one or more Metro ESM 8668 installed, you need to
install a jumper on each Metro ESM 8668 before installing the
SuperMezz. Follow the procedure "Installing the jumper on an ESM
8668" (page 139) before continuing with the next step.

2 Locate the CPU daughter card installation kit and remove the CPU
daughter card and installation hardware (see "CPU daughter card
installation kit" (page 137)).
Be sure your shipment includes all of the items shown in "CPU
daughter card installation kit" (page 137).

 138 Appendix B Installing the Metro Ethernet enhanced CPU daughter card

6 Press the daughter card assembly into the connectors on the

8692SF CPU (see "Mounting the CPU daughter card assembly to
the 8692 Series CPU" (page 138)).
Mounting the CPU daughter card assembly to the 8692 Series CPU

Make sure that the daughter card is properly seated in the

connectors.

7 Using the hex key, secure the daughter card to the 8692 Series CPU
using four socket head screws (items 3 and 4 in the installation kit)
(see "Securing the daughter card to the 8692 Series CPU" (page
139)).
Install the #2-56 x .625 screws first, followed by the #2-56 x .188
screws. See "Securing the daughter card to the 8692 Series CPU"
(page 139) for correct screw placement. You must insert the shorter
screws in the oval holes in the sheet metal daughter card bracket
and not through the daughter card. After you place the screw in the
hole, insert the hex key through the daughter card hole to secure
the screw in place.

CAUTION
Do not overtighten the screws. It is normal for a slight
space to be visible between the daughter card and the
standoffs.

Securing the daughter card to the 8692 Series CPU

8 Replace the 8692 Series CPU (with the newly installed daughter
card attached) into the vacant chassis slot (see "Installing and
replacing a module" (page 75)).
After you replace the 8692 Series CPU into the chassis, see the
appropriate chassis and component installation guide to power up
the chassis and verify a successful installation.

Installing the jumper on an ESM 8668

Install a jumper on the Metro Ethernet Services Module (Metro ESM 8668)
to ensure that the ESM 8668 boots successfully when a SuperMezz is
installed.

All ESM 8668 boards in your chassis must have a jumper installed.

Prerequisites
• Have the jumpers ready to install. You can order jumpers from Nortel
with the MERS 8600 ESM Jumper Kit (DS1411033-E6).

 140 Appendix B Installing the Metro Ethernet enhanced CPU daughter card

Procedure steps

Step Action

1 Disable the slot where the ESM 8668 is installed by using the CLI
command. Specify the number of the slot where the ESM 8668 is
installed for <slot-number>.
conf slot <slot-number> state dis
If you remove the ESM 8668 while active, ring failover times may
be longer than expected. Disabling the slot before removing the
ESM 8668 provides a clean disconnect from all services.

2 Remove the ESM 8668 from the chassis (see "Installing and
replacing a module" (page 75)).

3 Locate the 2x8 connector header, labeled P1, on the ESM 8668.
See "ESM 8668, P1 connector header" (page 140) for the location of
the P1 connector header.
ESM 8668, P1 connector header

4 Identify pins 5 and 6 on the P1 connector header where the jumper

gets installed. See "P1 connector header, pins 5 and 6" (page 141).
