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 3, “Mounting OS6400

Switches.” For instructions on hot swapping combo connector SFPs, refer to the OmniSwitch Transceiv-

ers Guide.

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 6400 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 6400 Series Chassis

and Hardware Components.” The show commands for all the features are described in detail in the

OmniSwitch CLI Reference Guide.
