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.
