Troubleshoot PICs

To troubleshoot PICs, follow these guidelines:

• 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 M20 and M40 Internet Routers PIC Guide.
• To check the status of a PIC, issue the following CLI command. The following example specifies an FPC slot number (3), which is optional. The PIC slots in the FPC are numbered from 0 (zero) through 3, top to bottom:
