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:
•
Switches (virtual NI modules) within a virtual chassis stack. Refer to
Stack" on page 6-25
•
1G uplink modules ("like" kinds only). Refer to
more information.
•
10G stacking modules ("like" kinds only). Refer to
more information.
•
Backup power supplies
•
Power supply connector cables
•
Transceivers. Refer to OmniSwitch 6250/6450 Transceivers Guide for more information.

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
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
Hardware Components."
