OmniSwitch 6850 Series Availability Features
Availability Features
The switch provides a broad variety of availability features. Availability features are hardware and
software-based safeguards that help to 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 to ensure that the switch or virtual chassis is consistently available for day-to-day
network operations.
Hardware-related availability features include:
• Software Rollback
• Backup Power Supplies
• Hot Swapping
• Hardware Monitoring
Software Rollback
Software rollback (also referred to as image rollback) essentially allows the OmniSwitch 6850 Series
switches to return to a prior “last known good” version of software in the event of a system software problem. The switch controls software rollback through its resilient directory structure design (i.e., /flash/
working and /flash/certified).
For detailed information on the software rollback feature, as well as the switch’s /flash/working and
/flash/certified directories, refer to the “Managing CMM Directory Content” chapter in the OmniSwitch
6800/6850/9000 Series Switch Management Guide.
Backup Power Supplies
The OmniSwitch 6850 Series switches support an optional backup power supply. This power supply is
connected to the rear of the unit. There is a power shelf provided with the unit that slides into the rear of
the chassis and is used to hold the power supplies. It can hold 510W or 360W power supply or in case of
non-PoE product switches 120W or 126W power supply. This provides redundant chassis power on a 1:1
basis.
Backup power supplies operate in active standby mode. If the primary power supply fails unexpectedly,
the backup power supply automatically takes up the full power load without disrupting the switch.
Note. For more information on backup power supplies, refer to Chapter 2, “OmniSwitch 6850 Series
Chassis and Hardware Components.”

Availability Features OmniSwitch 6850 Series
Hot Swapping
Hot swapping refers to the action of adding, removing, or replacing components without powering off
switches or disrupting other components.This feature facilitates hardware upgrades and maintenance and
allows users to easily replace components in the unlikely event of hardware failure.
The following hardware components can be hot swapped:
• Backup power supply
• Backup power supply connector cables
• SFPs
For instructions on hot swapping backup power supplies, refer to Chapter 2, “OmniSwitch 6850 Series
Chassis and Hardware Components.” For instructions on hot swapping combo connector SFPs, refer to the
instruction card provided with the SFP product.
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. (In the case of an over-threshold
temperature condition, the chassis displays an amber TMP LED in addition to sending a trap.)
LEDs
LEDs, which provide visual status information, are provided on the chassis front panel. LEDs are used to
indicate conditions such as hardware and software status, temperature errors, link integrity, data flow, etc.
For detailed LED descriptions, refer to Chapter 2, “OmniSwitch 6850 Series Chassis and Hardware
Components.”
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. Monitoring information for chassis components, such as the optional back up power supply,
chassis temperature sensor, and chassis fans is provided in Chapter 2, “OmniSwitch 6850 Series Chassis
and Hardware Components.” The show commands for all the features are described in detail in the
OmniSwitch CLI Reference Guide.

Combo SFP
The OS6850-24L provides four combo
SFP connectors for 1000Base-X highspeed connections.
By default, when an SFP is installed in a
combo port, it takes over the port number
of the corresponding RJ-45 Ethernet port.
In other words, if an SFP is installed in
the slot labeled 24, Ethernet port 24
would no longer be available and cannot
be used for 10/100/1000 traffic. This
default setting is referred to as “preferred
fiber.” Refer to “Configuring Ethernet” in
Network Configuration Guide for
the
detailed information, including
steps for
configuring combo port settings.

combo port, it takes over the port number
of the corresponding RJ-45 Ethernet port.
In other words, if an SFP is installed in the
slot labeled 24, Ethernet port 24 would no
longer be available and cannot be used for
10/100/1000 traffic. This default setting is
referred to as “preferred fiber.” Refer to
“Configuring Ethernet” in the Network
Configuration Guide for detailed information, including steps for configuring
combo port settings

Combo SFP
The OS6850-P24 provides four combo
SFP connectors for 1000Base-X high-
speed connections
.
By default, when an SFP is installed in a
combo port, it takes over the port number
of the corresponding RJ-45 Ethernet port.
In other words, if an SFP is installed in
the slot labeled 24, Ethernet port 24
would no longer be available and cannot
be used for 10/100/1000 traffic. This
default setting is referred to as “preferred
fiber.” Refer to “Configuring Ethernet” in
the Network Configuration Guide for
detailed information, including steps for
configuring combo port settings

Chassis Airflow
The fans pull air from the air intake vent located on the left-hand side of the chassis. The air is directed
horizontally through the chassis and past the circuit board. Airflow is then exhausted through the fan vents
at the right-hand side of the chassis. Refer to the illustrations below for more information.

OmniSwitch 6850 Series Chassis and Hardware Components Mounting the Switch
Blank Cover Panels
Blank cover panels are provided with your switch and are used to cover empty backup power supply bays
and 10 Gigabit uplink bays (all OmniSwitch 6850 Series switches, except for OmniSwitch 6850-24,
OmniSwitch 6850-P24, OmniSwitch 6850-48, and OmniSwitch 6850-P48). These cover panels play an
important role in chassis airflow and temperature management. They also protect the switch’s processor
board and other sensitive internal switch components from physical damage by closing off the chassis.
When blank cover panels are missing, air does not take the direct route from the air intake vent, through
the chassis, and then out through the fan exhaust vents (see page 2-58). Instead, a portion of the airflow is
allowed to be drawn in through the rear of the chassis. As a result, normal airflow is disrupted and an extra
task is placed on the fans to cool the chassis.
If your switch is not equipped with a backup power supply connection or 10 Gigabit uplink, and blank
cover panels are not installed over empty bay locations, airflow is adversely affected. Since they regulate
airflow and help protect internal chassis components, blank cover panels should remain installed over
empty bays at all times.

Installation Options
The OmniSwitch 6850 Series switches can be installed in two ways:
• Tabletop installation
• Rack-mount installation
Installing the Switch on a Tabletop or Bench
OmniSwitch 6850 Series switches can be installed freestanding as tabletop units. Place your switch on a
stable, flat, and static-free surface.
Note. OmniSwitch 6850 Series switches must be placed “right side up.” Never attempt to operate a switch
positioned on its side.
Tabletop Mounting Steps
To install the switch as a tabletop unit, follow the steps below:
1 Position the chassis on the table or bench where it is to be installed.
2 Be sure that adequate clearance has been provided for chassis airflow and access to the front, back, and
sides of the switch. For recommended clearances, refer to page 2-57. Also, be sure that you have placed
the chassis within the reach of all the required AC power sources.
3 If you are installing a single (i.e., stand-alone) switch, continue to “Setting Up a Stacked Configura-
tion” on page 2-63 for additional setup procedures.
If you are placing multiple switches in a stacked configuration, carefully stack the remaining switches, one
on top of the other. Up to eight switches may be stacked to form a single virtual chassis. Be sure to maintain adequate clearance at the front, rear, left, and right side of all switches (see page 2-57). Also, be sure
that you have placed all switches in the stack within reach of required AC power sources. Once the
switches are stacked together, continue to “Cabling Stacked Configurations” on page 2-63 for additional
setup procedures.
Note. Switches should be added one at a time in a stack.
Note. For comprehensive information on operating switches in a stacked configuration, refer to Chapter 4,
“Managing OmniSwitch 6850 Series Stacks.”

OmniSwitch 6850 Series Chassis and Hardware Components Mounting the Switch
Rack-Mounting the Switch
Refer to the important guidelines below before installing the OmniSwitch 6850 Series chassis on a rack.
• It is recommended that two people install the switch on the rack—one person to hold the chassis and
position it on the rack, and a second person to secure the chassis to the rack using attachment screws
(not supplied).
• Alcatel-Lucent provides two rack-mount flanges with each OmniSwitch 6850 Series switch. These
flanges support standard 19-inch rack-mount installations. These flanges must be attached to the chassis before the switch can be rack mounted.
Note. If you are installing the switch in a 23-inch-wide rack, Alcatel-Lucent offers optional 23-inch rackmounting hardware. For more information, contact your Alcatel-Lucent representative.
• 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 heavier equipment at
the bottom of the rack, whenever possible.
• If you are installing the switch on a relay rack, be sure to install and secure the rack per the rack manu-
facturer’s specifications.
• Review page 2-57 for important chassis airflow and access recommendations before installing.
Rack Mounting Steps
To rack-mount the switch, follow the steps below:
1 Align the holes in the provided rack-mount flanges with the four threaded holes in the OmniSwitch
6850 Series chassis. These threaded holes are located in the left and right sides of the chassis, near the
front panel.
2 Attach the flanges to the chassis using the provided Phillips-head screws. Be sure to tighten each of the
screws firmly using a Phillips screwdriver.

3 After the rack-mount flanges are secured to the chassis, mark the holes on the rack where the switch is
to be installed.
4 Lift and position the switch until the rack-mount flanges are flush with the rack post.
5 Align the holes in the flanges with the rack holes that were marked in step 3.
6 Once the holes are aligned, insert a rack mount screw (not provided) through the bottom hole of each
flange. Tighten both screws until they are secure.
Attaching the Switch to the Rack
Note. Be sure to install the screws in the bottom hole of each flange, as shown, before proceeding.
7 Once the screws at the bottom of each flange are secure, install the remaining two rack mount screws.
Be sure that all screws are securely tightened.
Note. If you are installing multiple switches in a rack to form a stacked configuration, refer to “Setting Up
a Stacked Configuration” on page 2-63.
Installing and Removing Combo Port SFPs
OmniSwitch 6850 Series switches offer four Gigabit Ethernet combo, located on the front panel (see page
2-23). These combo support hot-swappable fiber Small Form-Factor Pluggables (SFPs). For instructions
on installing and removing combo connector SFPs, refer to the instruction card provided with the SFP
product.
Note. Combo port preferences are user-configurable via the system software. Refer to the “Configuring
Ethernet” in the OmniSwitch 6850 Series Network Configuration Guide for complete details.

OmniSwitch 6850 Series Chassis and Hardware Components Setting Up a Stacked Configuration
Setting Up a Stacked Configuration
Rack Mounting Stacked Configurations
To rack mount a stacked configuration, install all switches that are to be included in the stacked configuration as described on pages 2-61 through 2-62. Up to eight switches may be stacked to form a single virtual
chassis.
Note. You cannot mix OS6800 and OS6850 switches in a stack.
Note. When rack mounting multiple switches in a stacked configuration, be sure to place all switches in
vertically-adjacent rack positions. This will ensure that all required stacking cables will have adequate
length for the installation.
Cabling Stacked Configurations
In order to connect stacked switches into a virtual chassis, all modules in the stack must be connected via
stacking cables (provided).
Redundant Stacking Cable Connections
In addition to the stacking cables installed between adjacent switch, the top-most switch and bottom-most
switch in the stack must be connected using a redundant stacking cable. Refer to Chapter 4, “Managing
OmniSwitch 6850 Series Stacks” for more information on the redundant stacking cable connection.
Supported Cabling Patterns
Each switch provides two stacking: stacking port A and stacking port B. Cables can be connected in any
pattern. In other words, the cable connected to stacking port A of one switch can be connected to either
stacking port A or stacking port B of the adjacent switch. However, it is strongly recommended that the
cabling pattern remains consistent across the stack. For a cabling diagram and additional information on
cabling the stack, refer to Chapter 4, “Managing OmniSwitch 6850 Series Stacks.”
Cabling Steps
1 Before inserting a stacking cable into one of the stacking, be sure to orient the stacking cable connec-
tor properly. The wide portion of the connector must be facing up. Refer to the diagram below for more
information.
Connector Top
When orienting the stacking cable connector, be sure
that the wider portion of the connector is facing up as
shown. Otherwise, the stacking cable will not fit
properly in the chassis’ stacking port.

Setting Up a Stacked Configuration OmniSwitch 6850 Series Chassis and Hardware Components
2 Starting from the top of the stack, insert one end of the stacking cable into either stacking port A or
stacking port B. The stacking port (A or B) depends on your preferred cabling pattern. Refer to Chapter 4,
“Managing OmniSwitch 6850 Series Stacks” for detailed information on cabling patterns. Be sure that
cable connector is completely inserted and fully seated in the chassis.
3 Insert the other end of the stacking cable into the stacking port of the switch immediately below. Once
again, the stacking port (A or B) depends on the preferred cabling pattern.
4 Repeat this procedure until all switches in the stack are connected (see illustrations a, b, and c below).
Reminder. The diagram below shows one supported stacking cable pattern. For additional supported
cabling patterns, refer to Chapter 4, “Managing OmniSwitch 6850 Series Stacks.”

OmniSwitch 6850 Series Chassis and Hardware Components Console Port
Console Port
The console port, located on the chassis front panel, provides a console connection to the switch and is
required when logging into the switch for the first time. By default, this RJ-45 connector provides a DTE
console connection.
Serial Connection Default Settings
The factory default settings for the serial connection are as follows:
baud rate 9600
parity none
data bits (word size) 8
stop bits 1
flow control none
Modifying the Serial Connection Settings
The switch’s serial connection defaults are listed above. If you wish to modify the default serial connection
settings (i.e., baud rate, parity, data bits, and stop bits), refer to the following steps:
Note. You must be connected to the switch via the console port before attempting to change serial connection settings. Otherwise, an error message will display.
For switches in a stacked configuration, all changes must be configured before the switches are cabled
together. In other words, you must configure these settings when each switch is operating as a stand-alone
unit.
1 Enter the modify boot parameters command at the CLI prompt. The boot prompt displays:
Boot >
2 To change the baud rate, enter boot serialbaudrate, followed by the desired baud rate value. Options
include 1200, 2400, 4800, 9600 (default), 19200, 38400, 57600, 76800, and 115200. For example:
Boot > boot serialbaudrate 19200
Note. Setting the console port to speeds above 9600 baud can cause problems with Zmodem uploads.
3 To change the parity value, enter boot serialparity, followed by the desired parity value. Options
include none (default), even, and odd. For example:
Boot > boot serialparity even
4 To change the data bits (i.e., word size) value, enter boot serialwordsize, followed by the number of
data bits. Options include 7 and 8 (default). For example:
Boot > boot serialwordsize 7
OmniSwitch 6850 Series Hardware Users Guide August 2007 page 2-69
Page 94
Console Port OmniSwitch 6850 Series Chassis and Hardware Components
5 To change the stop bits value, enter boot serialstopbits, followed by the number of stop bits. Options
include 1 (default) and 2. For example:
Boot > boot serialstopbits 2
6 Verify your current changes by entering show at the boot prompt:
Boot > show
Edit buffer contents:
Serial (console) baud : 19200
Serial (console) parity : even
Serial (console) stopbits : 2
Serial (console) wordsize : 7
(additional table output not shown)
7 You can save your changes to the boot.params file by entering commit file at the boot prompt:
Boot > commit file
When the commit file command is used, changes will not be enabled until after the next switch reboot.
8 You can also save your changes in real time to the switch’s running memory by entering commit
system at the boot prompt:
Boot > commit system
Caution. There are two important things to consider when using the commit system command to save
serial connection changes:
• Output to the terminal may become illegible due to incompatible serial connection settings between the
switch and the terminal emulation software.
• If you use the commit system command only, changes will not be saved to the switch’s boot.params
file and will be lost if the switch is rebooted. To save changes to the boot.params file, refer to step 7.
9 Return to the CLI prompt by entering exit at the boot prompt.

The power supplies can also be connected using a cable, in case there is a need for a less deep chassis. In
this case, the same power shelf can be mounted in the rack using the mounting ears (removable in case the
power supply needs to be plugged into the rear of the chassis).
Note. PoE units support either 510W or 360W power supplies. If unlike power supplies are mixed or if an
unsupported power supply (such as a 120W power supply) is used, a console message and a trap are generated.

Power Supply Shelf
Alcatel-Lucent requires the use of power supply shelf when the power supply is used in a 1U (i.e, 1.5
inches/3.8 cm) configuration. In a 2U (i.e., 3 inches/7.6 cm) configuration, if you have a 510W power
supply you can either use the power supply shelf or you can mount the 510W power supply directly to a
rack. See “Installing Power Supplies” on page 2-80 for more information.

PS-510W-AC Power Supply
The PS-510W-AC power supply (shown below) supports full switch and Power over Ethernet (PoE) functionality for 48-port OmniSwitch 6850 Series switches (e.g., OS6850-P48X). It can be installed as either
the primary or backup power supply. (See “Installing Power Supplies” on page 2-80 for more information.) A single 510W power supply allocates 390W for the POE functionality.
