Maintaining the Routing Engine on the SRX3400 Services Gateway

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

• Check the LEDs on the SFB faceplate.
• Check the LEDs on the Routing Engine faceplate.
• To check the status of the Routing Engine, issue the show chassis routing-engine command. The output is similar to the following:
  user@host> show chassis routing-engine

• To check the status of the SFB, issue the show chassis environment cb command. The output is similar to the following:
  user@host> show chassis environment cb
