Troubleshooting M120 PICs

Problem

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 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 2   Online       M120 FPC Type 1 
    PIC 2  Present      1x G/E, 1000 BASE-SX- Not Supported
    PIC 3  Online       1x Tunnel
