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

Slot 4 Online M120 FPC Type 3
Slot 5 Online M120 FPC Type 1
PIC 0 Online 1x G/E SFP, 1000 BASE

as described in “Troubleshooting M120 FEBs” on page 289.
