Intermittent problems Symptom FRU/action A problem occurs only occasionally and is difficult to diagnose. 1. Verify that: v All cables and cords are connected securely to the rear of the server and attached devices. v When the server is turned on, air is flowing from the rear of the server at the fan grill. If there is no airflow, the fan is not working.
