Replacing a Control Board

The Control Board can fail and not start, or it can cause a connectivity problem between the Routing Engine and the Packet Forwarding Engine components. You can perform a swap test on the Control Board to try to pinpoint the problem.

Action

To replace a Control Board, see Component Fuses in the M320 Router Midplane.

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