Troubleshooting the TX Matrix Host Subsystem

 

Problem:

Description:

The following indicate a problem with the host subsystem:

  • The OK LED on the Control Board is off.

  • The FAIL LED on the Control Board is lit green when the host subsystem detects a fault.

  • An alarm indicates that a host subsystem has been removed or failed.

  • The ONLINE LED on the RE-C1800 is lit red or is off.

  • The ONLINE LED on the RE-2000 is lit red or is off.

Solution

  1. Check the ONLINE LED on the Routing Engine faceplate. If the ONLINE LED is red, issue the chassis routing-engine command to check the status of the Routing Engines in the routing matrix.
    user@host> show chassis routing-engine
  2. Issue the show chassis alarms command to display Routing Engine alarms.
  3. Use the show chassis environment cb command to check the status of the Control Boards. The state should be Online.
    user@host> show chassis environment cb

The text in the column labeled ”LCD Message” appears in the display of the craft interface. The text in the column labeled “CLI Message” appears in the output from the show chassis alarms command.
