Step 4: Display the SIB Environmental Status

Action

To display the SIB environmental information, use the following CLI command:

user@host> show chassis environment

What it Means

The command output displays each component installed in the router, including the operating status and temperature.

Alternative Action

If there is a problem with the SIB status, you can display more detailed environmental information with the following CLI command:

user@host> show chassis environment sib

The command output displays the SIB slot, status, and temperature of the air flowing past the SPP card and the power supply voltages.

You can display the environmental status of a particular SIB with the following CLI command:

user@host> show chassis environment sib slot
