LED

Color

Status

Attention

Flashing Blue

The operator has activated this LED to identify this chassis.

Solid Blue

During bootup, if secure boot validation check fails on BIOS, it causes the router to halt the booting process. During run time, if secure JTAG detect tampering attempt to the CPU JTAG chain, then the router halts the CPU and sets the LED into this state.

Note

 

The router displays two LEDs. Solid Blue for Attention LED and Solid Red for Status LED.

Off

The operator has not activated this LED.

Status

Solid Amber

The module is in one of the following states:

  • Booting up

  • Shutting down

  • Power cycling

  • Installing image

Solid Green

This module is operational with no issues.

Flashing Green

Auto or Manual FPD upgrade is in-progress.

Flashing Amber

The module has an active minor alarm.

Flashing Red

The module has an active major or critical alarm.

Solid Red

The module is in one of the following states:

  • Power-up failure that prevents the CPU from booting.

  • During bootup, if secure boot validation check fails on BIOS, it causes the router to halt the booting process. During run time, if secure JTAG detect tampering attempt to the CPU JTAG chain, then the router halts the CPU and sets the LED into this state.

    Note

     

    The router displays two LEDs. Solid Blue for Attention LED and Solid Red for Status LED.

Off

The module is in one of the following states:

  • The module is in shutdown state by using either shutdown location location command in the EXEC mode or by using the hw-module shutdown location location command in the Config mode.

  • While the card is in running state, the ejector lever is opened that triggers the auto-shutdown operation for the module.

  • The module is placed in shutdown state by the software due to a hardware fault or a critical alarm condition.
