Troubleshooting the T1600 FPCs

Problem

The following LEDs indicate a problem with an FPC:

• The red FAIL LED above the FPC is on.

During normal operation:

• The green STATUS LED above the FPC on the craft interface lights steadily when the FPC is online and functioning normally.
• The green STATUS LED blinks during startup.

Solution

To troubleshoot an FPC:

1. Look at the display on the craft interface to check the status of the FPC and the PICs that are plugged into it.
2. Verify that the FPC is properly seated in the midplane. Check that each ejector handle has been turned clockwise and is tight. Use a screwdriver to check that the screws inside the ejector handles are tight.
3. Check the status of an FPC using the following CLI command:
   
   

   user@host> show chassis fpc
4. Use the following option to display more detailed information:
