Troubleshooting M120 PICs

 

Problem:

Description: The PICs are not functioning normally.

Solution

To troubleshoot the PICs:

  • Check the status of each port on a PIC by looking at the LED located on the PIC faceplate. For information about the meaning of LED states on different PICs, see the M120 Multiservice Edge Router Interface Module Reference.

  • To check the status of a PIC, issue the following CLI command. The PIC slots in the FPC are numbered from 0 through 3, top to bottom:

    user@host> show chassis fpc pic-status
    Note

    If a PIC does not come online as expected, check the assigned FEB, as described in Troubleshooting M120 FEBs.

    For further description of the output from the command, see the CLI Explorer.
