Step 5: Perform an FPC Swap Test

CAUTION: Before performing a swap test, always check for bent pins in the midplane and check the FPC for stuck pins in the connector. Pins stuck in the component connector can damage other good slots during a swap test.

Action

To perform a swap test on an FPC, follow these steps:

1. Remove the FPC that you suspect has failed from the router chassis.
2. Inspect the router midplane for bent pins. Inspect the FPC connector for pins that are stuck. If you find a bent or stuck pin, see Return the Failed Component.
3. If there are no bent or stuck pins and there is a spare FPC slot in the router, insert the FPC that failed into a spare slot. If the FPC still fails, see Return the Failed Component. If there is no spare FPC slot, insert an FPC that you know works into the slot where the FPC failed. If the FPC works, the replaced FPC failed. If the FPC does not work, the FPC slot has failed.
