Troubleshooting the M320 PICs

To troubleshoot the PICs:

• To check the status of each port on a PIC, look at the LED located on the PIC faceplate. For information about the meaning of LED states on different PICs, see the M320 Multiservice Edge Router PIC Guide.
• 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

  Slot 0 Online
    PIC 0    4x OC-3 SONET, MM
    PIC 1    1x CSTM1, SMIR
    PIC 3    2x OC-3 ATM, MM
  Slot 1 Online
    PIC 0    1x OC-12 SONET, MM
    PIC 1    1x OC-12 ATM, MM
    PIC 2    2x OC-3 ATM, MM
    PIC 3    2x OC-3 ATM, MM
