Troubleshooting the MX480 MICs

Problem

The MICs are not functioning normally.

Solution

• 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, see the MX Series 3D Universal Edge Routers Line Card Guide .
• 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, left to right:
  user@host> show chassis fpc pic-status
