page 1-2 OmniSwitch 6850 Series Hardware Users Guide August 2007
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.”
OmniSwitch 6850 Series Hardware Users Guide August 2007 page 1-3
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.

Console Port
The OS6850-24L front panel
provides one RJ-45 port for console connections. Console connections are used by network
administrators for switch management. This female RJ-45 connector provides a DTE console
connection.
10/100 Mbps and 10/100/1000Mbps
The OS6850-24L provides 20 fixed
10/100BaseT non-combo (1–20) and 4
fixed
10/100/1000BaseT combo 21–24).
These are auto-sensing and auto-MDIX
and use RJ-45 connectors.

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.
