Maintaining Host Subsystem in EX9200 Switches
Purpose For optimum performance of an EX9200 switch, verify the condition of the host
subsystem. Thehost subsystem comprises a Switch Fabric and a RoutingEngine. Routing
Engine module (RE module) is installed directly into a Switch Fabric module (SF module).
Action On a regular basis:
• 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
