Troubleshooting FPCs

As soon as an FPC is seated on an operating router, the Routing Engine downloads the FPC software to it. The FPC then runs diagnostics and enables the PICs housed on it. During this time, the green FPC LED labeled OK on the craft interface is blinking. When the FPC is online and functioning normally, the OK LED lights steadily.

To troubleshoot the FPCs, follow these guidelines:

• If the amber FPC LED labeled FAIL on the craft interface lights steadily, make sure the FPC is properly seated in the midplane. Use a Phillips screwdriver to check that the screws at the top and bottom of the card carrier are tight.
• To check the status of an FPC, issue the CLI show chassis fpc command. As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:
  user@host> show chassis fpc

                Temp  CPU Utilization (%)   Memory    Utilization (%)
  Slot State     (C)  Total  Interrupt      DRAM (MB) Heap     Buffer
    0  Online     37      4          0        32         1         39
    1  Online     39      4          0        32         1         39
    2  Empty
    3  Online     34      4          0        32         1         39
   

  For more detailed output, add the detail option. The following example also specifies a slot number (0), which is optional:

  
  user@host> show chassis fpc detail 0

  Slot 0 information:
