Troubleshooting the TX Matrix Plus Routing Engines

Problem

During normal operation, the ONLINE LED on each Routing Engine is lit green, indicating that the Routing Engine is functional.

The following indicate a problem with the Routing Engine:

• The ONLINE LED on the Routing Engine faceplate is lit steadily red.
• An alarm indicates that a host subsystem has been removed or failed.

Solution

1. Check the ONLINE LED on the Routing Engine faceplate. If the ONLINE LED is red, issue the chassis routing-engine sfc 0 command to check the status of the Routing Engine.
   
   

   user@host> show chassis routing-engine sfc 0
