I/O Module LEDs

LED Color Status

ID

Flashing blue

The operator has activated this LED to identify this module in the chassis.

Off

This LED is not being used.

Status

Green

All diagnostics passed. This module is operational (normal initialization sequence).

Amber

Indicates one of the following:

  • The module is booting or running diagnostics.

  • An overtemperature condition has occurred. (A minor temperature threshold has been exceeded during environmental monitoring.)

Flashing red

Indicates one of the following:

  • The switch has just been powered on, and the module is resetting.

  • The module has been inserted during the initialization process.

  • An overtemperature condition has occurred. A major temperature threshold has been exceeded during environmental monitoring

  • The module has failed to download code and configuration information successfully during the initial reset. The module is not online.

Red

Indicates one of the following:

  • The module has detected a slot ID parity error and will not power on or boot up.

  • The module is not fully inserted, and it is not making a reliable connection with the supervisor.

Off

The module is not receiving power.

Link (for each port)

Green

The port is active (the link is connected and active).

Amber

The module or port is disabled by using a CLI command or the module is initializing.
