Troubleshoot 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 that it houses. 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 FPCs, follow these guidelines:

• If the red FPC LED labeled FAIL lights steadily, make sure the FPC is properly seated in the backplane—use a Phillips screwdriver to check that the screws at the top and bottom of the card carrier are tight.
• Issue the CLI show chassis fpc command to check the status of installed FPCs. 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

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