Troubleshooting the MX2020 MICs

 

Problem

Description: A MIC LED lit red indicates a problem with the MIC.

Solution

To troubleshoot a MIC:

  1. Check the status of each port on a MIC by looking at the LED located on the MIC faceplate. For information about the meaning of LED states on different MICs. For more information, see the MX Series Interface Module Reference
  2. Check the status of a MIC by issuing the show chassis fpc pic-status CLI command. The MIC slots in the MPC are labeled PIC 0/1 and PIC 2/3, top to bottom:
    user@host> show chassis fpc pic-status

    For further description of the output from the command, see the Junos OS System Basics and Services Command Reference  .
