OmniSwitch 6900 OmniSwitch 6900 Availability Features

OmniSwitch 6900 Availability Features

The switch provides a broad variety of availability features. Availability features are hardware and
software-based safeguards that help prevent the loss of data flow in the unlikely event of a subsystem
failure. In addition, some availability features allow users to maintain or replace hardware components
without powering off the switch or interrupting switch operations. Combined, these features provide added
resiliency and help ensure that the switch is consistently available for day-to-day network operations.
Hardware-related availability features include:
• Power Supply Redundancy
• Hot-Swapping
• Hardware Monitoring

Power Supply Redundancy

For information on power supply redundancy, refer to Chapter 3, “Chassis and Power Supplies.”

Hot-Swapping
Hot-swapping refers to the action of adding, removing, or replacing certain hardware components without
powering off your switch and disrupting other components in the chassis. This feature greatly facilitates
hardware upgrades and maintenance and also allows you to easily replace components in the unlikely
event of hardware failure. The following hardware components can be hot-swapped:
• Power supplies

• Transceivers

• Fan tray

• Plug-in modules

Note. Hot-swapping guidelines apply to the various modules. In some cases a reboot is required. Refer to
“Hot-Swapping Plug-In Modules” on page 3-46 for detailed information on hot-swapping plug-in
modules.

For information on adding and removing power supplies and plug-in modules, refer to Chapter 3, “Chassis
and Power Supplies.”

OmniSwitch 6900 Hardware Users Guide July 2021 page 1-3

OmniSwitch 6900 Availability Features OmniSwitch 6900

Hardware Monitoring
Automatic Monitoring
Automatic monitoring refers to the switch’s built-in sensors that automatically monitor operations. If an
error is detected (e.g., over-threshold temperature), the switch immediately sends a trap to the user. The
trap is displayed on the console in the form of a text error message.

LEDs
LEDs, which provide visual status information, are provided on the front and rear panels. LEDs are used
to indicate conditions, such as hardware and software status, link integrity, data flow, etc. For detailed
LED descriptions, refer to the corresponding hardware component section in the next chapter.

User-Driven Monitoring
User-driven hardware monitoring refers to CLI commands that are entered by the user in order to access
the current status of hardware components. The user enters “show” commands that output information to
the console. The Show commands for all the features are described in detail in the OmniSwitch CLI
Reference Guide.

national electrical codes.

OmniSwitch 6900 switches have the following general electrical requirements:

• Each switch requires one grounded electrical outlet for each power supply installed in the chassis.
OmniSwitch 6900 switches offer both AC and DC power supply support.
• For switches using AC power connections, each supplied AC power cord is 2 meters (approx. 6.5 feet).
Do not use extension cords.

OmniSwitch 6900 Hardware Users Guide July 2021 page 2-1

Installing the Hardware Getting Started

Redundant AC Power. It is recommended that each AC outlet resides on a separate circuit. With
redundant AC, if a single circuit fails, the switch’s remaining power supplies (on separate circuits) can
remain operational.

• For switches using DC power, refer to the “DC Power Supply Connections” on page 3-34 for
more information.

Electrical Surge Warning

In order to help protect equipment against electrical surges please take note of the following
recommendations and guidelines:
1 Earth grounding of all devices is fundamental to ensure long term reliability.

• All electrical equipment must be installed by a qualified, licensed electrician.

• Every power supply that is connected to building power should be earth grounded.

• Earth grounding for the power cable, should be verified to be 0.01 ohm or less.

• Each switch should be grounded to same earth ground as the power supply.

• Each powered device, such as an AP or camera, should be connected to earth ground.

• Each surge suppression device should be connected to earth ground.

2 Shielded cables (STP) offer some minimal level of additional protection over unshielded Ethernet
cables (UTP) but the use of a surge protector is still recommended.
• It is suggested to use STP Cat5e or better for 1Gbps Ethernet switches for any outdoor application or
applications where Ethernet cables come in close proximity to alternating current conductors.
• Always install cables according to manufacturer requirements.

3 For any connections where integrity of the cabling within a building ground is questionable (i.e outdoor
connections), copper Ethernet ports must be connected with an appropriate surge protection device, inline,
between the PSE and PD per the manufacturer’s recommendations for connection and grounding.
4 Caution should be taken for any cable connected to any outdoor device, not only on the device ground-
ing, but to ensure that any outdoor device cables that could carry surge currents, do not pass those surge
currents to upstream Ethernet switches.
5 Caution - Category 5e, Category 6, and Category 6a cables can store large amounts of static electricity
due to the dielectric properties of their construction materials in addition, this build up of electricity could
lead to a Cable Discharge Event (CDE). A CDE can occur due to the differential in charges on the cable
and the equipment it’s being connected to. It is recommended that installers momentarily ground all
copper Ethernet cables (especially in new cable runs) to a suitable and safe earth ground before connect-
ing them to the port.

Note. Failure to follow the above recommendations could result in voiding the warranty of the affected
ALE product.

Getting Started Your First Login Session

Setting IP Address Information for the EMP

IP address can be set via the Ethernet Management Port (EMP). To connect to the switch through the EMP
Ethernet connection, use the default address below or change the port’s IP address.

Default EMP IP Address 192.168.1.1

Default EMP Mask 255.255.255.0

Note. You should be connected to the switch via the console port before attempting to change IP
address information.

To change the default IP and mask, use the ip interface command. For example:

-> ip interface emp address 168.22.2.120 mask 255.255.255.0

Verify your settings using the show ip interface command. See the OmniSwitch AOS Switch Manage-
ment Guide for additional information regarding EMP port addressing.

Note. Although you have configured the EMP with valid IP address information, you will not be able to
access the switch through this port (i.e. TELNET, FTP, HTTP, SSH or SNMP) until you have unlocked
these remote session types. See “Unlocking Session Types” on page 2-10 for more information.

OmniSwitch 6900 Hardware Users Guide July 2021 page 2-9

Your First Login Session Getting Started

Unlocking Session Types

Security is a key feature on OmniSwitch 6900 switches. As described on page 2-8, when you access the
switch for the first time, you must use a direct console port connection. All other session types (Telnet,
FTP, WebView, and SNMP) are locked out until they are manually unlocked by the user.
The CLI command used to unlock session types is aaa authentication.

Note. When you unlock session types, you are granting switch access to non-local sessions (e.g., Telnet).
As a result, users who know the correct user login and password will have remote access to the switch. For
more information on switch security, refer to the OmniSwitch AOS Switch Management Guide.

Unlocking All Session Types

To unlock all session types, enter the following command syntax at the CLI prompt:
-> aaa authentication default local

Unlocking Specified Session Types

You can also unlock session types on a one-by-one basis. For example, to unlock Telnet sessions only,
enter the following command:
-> aaa authentication telnet local

To unlock WebView (HTTP) sessions only, enter the following command:

-> aaa authentication http local

You cannot specify more than one session type in a single command line. However, you can still unlock
multiple session types by using the aaa authentication command in succession. For example:
-> aaa authentication http local

-> aaa authentication telnet local

-> aaa authentication ftp local

Refer to the OmniSwitch CLI Reference Guide for complete aaa authentication command syntax options.

Changing the Login Password

Change the login password for admin user sessions by following the steps below:

1 Be sure that you have logged into the switch as user type admin (see “Logging In to the Switch” on
page 2-8).
2 Enter the keyword password and press Enter.

3 Enter your new password at the prompt.

Note. Be sure to remember or securely record all new passwords; overriding configured passwords on an
OmniSwitch is restricted.

page 2-10 OmniSwitch 6900 Hardware Users Guide July 2021

Getting Started Your First Login Session

4 You will be prompted to re-enter the password. Enter the password a second time.

New password settings are automatically saved in real time to the local user database; the user is not
required to enter an additional command in order to save the password information. Also note that new
password information is retained following a reboot. All subsequent login sessions, including those
through the console port, will require the new password to access the switch.
For detailed information on managing login information, including user names and passwords, refer to the
OmniSwitch AOS Switch Management Guide.

Setting the System Time Zone

The switch’s default time zone is UTC. If you require a time zone that is specific to your region, or if you
need to enable Daylight Savings Time (DST) on the switch, you can configure these settings via the
system timezone and system daylight-savings-time commands.
For detailed information on configuring a time zone for the switch, refer to the OmniSwitch AOS Switch
Management Guide.

Setting the Date and Time

Set the current time for the switch by entering system time, followed by the current time in hh:mm:ss.
To set the current date for the switch, enter system date, followed by the current date in mm/dd/yyyy.

Setting Optional Parameters

Specifying an Administrative Contact

An administrative contact is the person or department in charge of the switch. If a contact is specified,
users can easily find the appropriate network administrator if they have questions or comments about the
switch.
To specify an administrative contact, use the system contact command.

Specifying a System Name

The system name is a simple, user-defined text description for the switch. To specify a system name, use
the system name command.

Specifying the Switch’s Location

It is recommended that you use a physical labeling system for locating and identifying your switch(es).
Examples include placing a sticker or placard with a unique identifier (e.g., the switch’s default IP
address) on each chassis.
However, if no labeling system has been implemented or if you need to determine a switch’s location from
a remote site, entering a system location can be very useful.
To specify a system location, use the system location command.

Network Port Status LEDs (OS6900-Q32 and OS6900-X72 Switches)

Because OS6900-Q32 and OS6900-X72 models provide splitter cable support on selected QSFP+ ports
(see page 3-6 and page 3-12), port LED behavior for these switches differs from other OS6900 models.
While it is important to note all details listed in the table below, general “at-a-glance” associations can be
made when viewing LED colors. E.g., green typically indicates 40G (non-VC); yellow indicates 4X10G
(non-VC) and blue indicates 40G or 4X10G in a VC configuration. More detailed port LED behavior is

4X10G Splitter Cable LED Indicators

When a port LED flashes white, a 4X10G splitter cable is installed. The white display is used as an
indicator that separates the status for each of the four splitter cable sub ports. E.g., when the LED flashes
white for a long duration, the status for sub port A displays next. When the LED subsequently flashes
white for a shorter duration, the status for sub port B displays, etc. When the status for all four of the
splitter cable’s sub ports has displayed, the cycle repeats:

1. LED flashes white for a 2. LED flashes white for a

long duration; status for short duration; status for
sub port A displays next. sub port B displays next.

4. LED flashes white for a 3. LED flashes white for a

short duration; status for short duration; status for
sub port D displays next. sub port C displays next.

Mounting the Switch Chassis and Power Supplies

Mounting the Switch

General Mounting Recommendations
Elevated Operating Ambient Temperature. If installed in a closed or multi-rack assembly, the operating
ambient temperature of the rack environment may be greater than the room’s ambient temperature.
Therefore, consideration should be given to the maximum rated ambient temperature (Tmra) given for the
individual chassis specifications.
Reduced Air Flow. Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Refer to “Airflow Recommendations” on
page 3-37 for more information.
Mechanical Loading. Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven loading.
Circuit Overloading. Consideration should be give to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on overcurrent protection and supply wiring.
Reliable Earthing. Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch (e.g., use of
power strips).

Chassis and Power Supplies Mounting the Switch

Airflow Recommendations
To ensure proper airflow, be sure that your switch is placed in a well-ventilated area and provide
minimum recommended clearance at the front, back and sides of the switch, as shown below. Restricted
airflow can cause your switch to overheat, which can lead to switch failure. Refer to the following
important guidelines regarding airflow:
• The switch supports both Front-to-Rear and Rear-to-Front airflow depending on the fan tray and power
supplies installed. The airflow direction of the power supplies and fan tray must be the same.
• Running a mismatched fan tray or power supply will cause an error and trap to be displayed.
Eventually the mismatched configuration will cause the chassis to reboot to avoid overheating.
• Follow the guidelines below regarding the minimum clearance requirements when mounting
the chassis.

} Rear. 6 inches minimum

at rear of chassis.

Sides. 2 inches minimum

at left and right sides.

} Front. 6 inches minimum

at front of chassis.

Mounting the Switch Chassis and Power Supplies

Front-to-Rear Airflow
The OmniSwitch 6900 fan tray and power supplies are located at the rear of the switch and draw air
through the intake vents located at the top-front of the chassis. The air is directed straight through the
chassis’ module compartment and past the switch’s circuit boards. Airflow is then exhausted through
their vents.

Chassis Airflow - Front to Rear

Rear-to-Front Airflow
The OmniSwitch 6900 fan tray and power supplies are located at the rear of the switch and draw air
through their vents located at the rear of the chassis. The air is directed straight through the chassis’
module compartment and past the switch’s circuit boards. Airflow is then exhausted through the air vents
on the top-front of the chassis.

Airflow Mismatch
If an airflow mismatch is detected at bootup, OK and PS LEDs blink green/amber and the GRN LED
blinks green (see “Chassis Status LEDs” on page 3-28), warnings display, and the switch continuously
reboots until the issue is corrected.
If an airflow mismatch is detected after the switch has fully booted (e.g., when a fan tray or power supply
is hot-inserted) OK and PS LEDs blink amber and the GRN LED blinks green (see “Chassis Status LEDs”
on page 3-28, warnings displayed, switch will reboot when it reaches temperature danger threshold.

Color Coding
To help users avoid mismatched fan trays and power supplies, rear-to-front components are marked with
purple color coding. (Front-to-rear components use standard product colors.)

OmniSwitch 6900 Hardware Users Guide July 2021 page 3-39

Mounting the Switch Chassis and Power Supplies

Blank Cover Panels

Blank cover panels are provided with your switch and are used to cover empty slots. These cover panels
play an important role in chassis airflow and temperature management. If your switch is not fully
populated and blank cover panels are not installed over empty slot locations, airflow is affected.
When blank cover panels are missing, air does not take the direct route from the air intake vents, through
the chassis module compartment, and out through the fan’s exhaust vent as intended. Instead, a portion of
the airflow is allowed to escape through other openings in the chassis. As a result, normal airflow is
disrupted and an extra task is placed on the fan tray to cool the chassis.
Cover panels also provide protection for module processor boards and other sensitive internal switch
components by closing off a chassis that is not fully populated.

Note. Because they regulate airflow and help protect internal chassis components, blank cover panels
should be installed over empty module slots and power supply bays at all times.

Chassis and Power Supplies Rack-Mounting

Rack-Mounting
Refer to the following important guidelines before installing the chassis in a rack:
• Two people are required to rack mount the switch: One person to lift the chassis into position and one
person to secure the chassis to the rack using the rack mount screws.
• The chassis has rack-mount flanges that support standard 19-inch rack mount installations.
• Alcatel-Lucent does not provide rack-mount screws. Use the screws supplied by the rack vendor.
• To prevent a rack from becoming top heavy, it is recommended that you install the switch at the
bottom of the rack whenever possible.
• If you are installing the switch in a relay rack, be sure to install and secure the rack per rack
manufacturer’s specifications.
To rack mount the switch, follow the steps below.

Note. Because of the overall chassis depth, additional support braces are used to support the rear of the
chassis and prevent sagging in the rack. These braces are required for all rack-mound installations.

1 Mark the holes on the rack where the chassis is to be installed.

2 Attach two slot rails to the left and right side of the chassis.

3 One person should lift and position the chassis until the rack-mount flanges are flush with the
rack post.
4 Align the holes in the flanges with the rack holes marked in step 1.

OmniSwitch 6900 Hardware Users Guide July 2021 page 3-41

Rack-Mounting Chassis and Power Supplies

5 Once the holes are aligned, the second person should insert a screw through the bottom hole on each
flange. Tighten both screws until they are secure.

Chassis Front

6 From the back of the chassis and with the flanges facing out, insert the slide-in braces into the slot rails
until they meet the rack posts.

Chassis Rear

7 The chassis installation should be level. Be sure that the holes and flanges of the slide-in brace are
aligned with the corresponding holes at the front of the rack.
8 Once the flanges are aligned, install the remaining screws in all four flanges. Be sure that all screws are
securely tightened.

Note. Never rack mount OS6900 switches using only the front-installed rack mount flanges. Due to the
chassis overall depth, OS6900 switches must be mounted using additional support braces (available from
Alcatel-Lucent) or by attaching flanges to the mid portion of the chassis (using the threaded holes
provided). Failure to properly mount the switch may result in the chassis sagging in the rack or damage to
the switch and its components. Refer to the following sections for more information.

page 3-42 OmniSwitch 6900 Hardware Users Guide July 2021

Chassis and Power Supplies Rack-Mounting

Mid-Mounting the Chassis In the Rack

The switch may also be installed in the rack using mid-mount flanges. To mid-mount the switch in a rack,
follow the steps below.
1 If needed, remove the mounting flanges from the front of the chassis and the slot rails from the side of
the chassis by unscrewing the attachment screws.
2 Reinstall the mounting flanges at the mid point of the chassis using the threaded holes, as shown in the
diagram below.

3 Mark the holes on the rack where the chassis is to be installed.

4 One person should lift and position the chassis until the mid-mount flanges are flush with the rack post.

5 Align the holes in the flanges with the rack holes marked in step 3.

Standalone (Non-Rack Mounted) Installations

The chassis can also be placed unmounted on a stable, flat surface as a standalone unit. Be sure that the
surface can accommodate the full, populated weight of all switches being installed.

Weight Considerations
Depending on model type, an empty OmniSwitch 6900 chassis weighs up to 7.78 kg (17.15 lbs).
When fully populated with fan tray, power supplies and plug-in modules, the OmniSwitch 6900 can weigh
up to 10.86 kg (23.95 lbs). (Weights to not include transceivers or cabling.)

Proper Clearance
For a standalone unit, be sure that adequate clearance has been provided for chassis airflow and that you
have placed the chassis within reach of all required AC outlets. For recommended airflow allowances,
refer to page 3-37.

Note. Chassis must be placed “right side up.” Never attempt to operate a switch while it is placed on its
top or side.

Chassis Fan Tray Chassis and Power Supplies

Chassis Fan Tray

The OmniSwitch 6900 chassis houses a single fan tray with four independently-operating fan or multiple
fan trays depending on the model. The fans are the main temperature control components for the switch,
providing cooling airflow for all chassis components. This airflow is a crucial factor in the switch’s overall
operability. Refer to “Airflow Recommendations” on page 3-37 for more information.

Important. The fan tray is a required component. Never attempt to operate the switch without a fan
tray installed

Airflow Direction
The fan tray is available in front-to-rear airflow or rear-to-front airflow models. Power supplies are also
direction-specific (front-to-rear or rear-to-front). When installing a fan tray in the chassis, it must match
the airflow direction of the power supplies. (See “Airflow Mismatch” on page 3-39 for more information.)

Grounding the Chassis Chassis and Power Supplies

Grounding the Chassis

The switch has a grounding lug located on the rear of the chassis. This lug uses 10-32 screws and is
surrounded by a small paint-free area, which provides metal-to-metal contact for a ground connection.
Use this connector to supplement the ground provided by the AC power cord. To do so, install a Panduit
Grounding Lug (type LCD8-10A-L) using 8AWG copper conductors to the paint-free area.
Refer to the rear chassis views on page 3-2 for location details.

Monitoring Chassis Temperature

The operating temperature of your switch is a critical factor in its overall operability. In order to avoid a
temperature-related system failure, your switch must always run at a temperature within the specified
operating temperature range. Refer to the chassis specifications section for additional information.
To avoid chassis over-temperature conditions, follow the important chassis airflow recommendations
on page 3-37.

To check the switch’s current temperature status, use the show temperature command:

-> show temperature

For more information about this command, see the “Chassis Management and Monitoring Commands”
chapter in the OmniSwitch AOS Release 8 CLI Reference Guide

OmniSwitch 6900 Hardware Users Guide July 2021 page 3-65

Monitoring Chassis Temperature Chassis and Power Supplies

Temperature Errors
The switch monitors the ambient air temperature at all times via an onboard sensor. If an over-temperature
condition occurs, there are two different levels of error severity:
• Warning threshold has been exceeded

• Danger threshold has been exceeded

Warning Threshold
If the temperature exceeds the switch’s warning threshold, the switch sends out a trap. Traps are printed to
the console in the form of text error messages.
When the warning threshold has been exceeded, switch operations remain active. However, it is
recommended that immediate steps be taken to address the over-temperature condition.
Addressing warning threshold temperature conditions may include:
• Checking for a chassis airflow obstruction

• Checking the ambient room temperature

• Checking the fan tray status using the show fan command. See page page 3-66 for more information.

Note. For the OS6900’s default warning threshold value, refer to the specifications on page 3-2. The
warning threshold may be viewed using the show temperature command.

Temperature Danger Threshold

If the chassis ambient air temperature rises above the danger threshold (see specifications on page 3-2) the
switch will power off until the temperature conditions have been addressed and the switch is manually
booted. The danger threshold is factory-set and cannot be configured by the user.
Addressing danger threshold temperature conditions may include:
• Checking for a chassis airflow obstruction or direction mismatch.

• Checking the ambient room temperature

• Checking the fan tray status using the show fan command. See page page 3-66 for more information.

Monitoring Fan Tray Status

The switch constantly monitors fan operation. If any of the switch’s fans unexpectedly shuts down, the
switch sends out a trap and the FAN LED on the chassis front panel displays amber.
To check the switch’s current fan tray status, use the show fan command. For example:

-> show fan

For more information about this command, see the “Chassis Management and Monitoring Commands”
chapter in the OmniSwitch CLI Reference Guide.
