Maintaining the Host Subsystem

The host subsystem comprises a Routing Engine installed directly into an SCB. To maintain the host subsystem components, follow these guidelines:

To check the status of a specific SCB, issue the show chassis environment cb command and include the slot number of the SCB. The output is similar to the following:


user@host> show chassis environment cb 0
CB 0 status:
  State                      Online
  Temperature Intake         66 degrees C / 150 degrees F
  Temperature Exhaust A      67 degrees C / 152 degrees F
  Temperature Exhaust B      73 degrees C / 163 degrees F
