Maintaining Host Subsystem in EX9208 Switches

Purpose

For optimum performance of an EX9208 switch, verify the condition of the host subsystem. The host subsystem comprises a Switch Fabric and a Routing Engine. Routing Engine (RE) module is installed directly into a Switch Fabric (SF) module.

Action

• Check the LEDs on the craft interface to view information about the status of the Routing Engines.
• Check the LEDs on the SF module faceplate.
• Check the LEDs on the RE module faceplate.
• To check the status of the Routing Engines, issue the show chassis routing-engine command. The output is similar to the following:
  user@switch> show chassis routing-engine
