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 high-impact
network operations.
Hardware-related availability features include:
• Software Rollback
• Hot Swapping
• Hardware Monitoring
• Backup Power Supplies
Software Rollback
Software rollback (also referred to as image rollback) essentially allows the switch to return to a prior “la st
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 Switch
Management Guide.
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 components can be hot swapped:
• Backup power supplies
• Power supply connector cables
• SFPs
Note. For instructions on hot swapping backup power supplies, refer to Chapter 4, “Mounting OS6250
Switches” For instructions on hot swapping combo connector SFPs, refer to the instruction card provided
with the SFP.

OmniSwitch 6250 Availability Features
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 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 3, “OmniSwitch 6250 Chassis and Hardware Compo-
nents.”
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 3, “OmniSwitch 6250 Chassis and
Hardware Components.” The show commands for all the features are described in detail in the OmniS-
witch CLI Reference Guide.
Backup Power Supplies
Some OmniSwitch 6250 switches support an optional backup power supply. 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 power supplies, refer to Chapter 3, “OmniSwitch 6250 Chassis and Hard-
ware Components.”

Getting Started Your First Login Session
Unlocking Session Types
Security is a key feature on OmniSwitch 6250 switches. As described on page 2-6, 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 th e switc h. For
more information on switch security, refer to the OmniSwitch AOS Release 6 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.
OmniSwitch 6250 Hardware Users Guide September 2015 page 2-7
