Table 20. Intermittent problems and actions
Symptom Action
A problem occurs only
occasionally and is difficult to
diagnose. 1. Make sure that:
• All cables and cords are connected securely to the rear of the server and
attached devices.
• When the server is turned on, air is flowing from the fan grille. If there is
no airflow, the fan is not working. This can cause the server to overheat
and shut down.
2. Check the system-error log or IMM2 event log (see “Event logs” on page 122).
