  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).
