See Chapter 4, "Parts listing, " to determine which components are customer
replaceable units (CRU) and which components are field replaceable units
(FRU).
If an action step is preceded by "(Trained service technician only)," that step
must be performed only by a trained service technician.
Action
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 grill. If
there is no airflow, the fan is not working. This can cause the
server to overheat and shut down.
2. Check the event logs (see "Event logs").
3. See "Solving undetermined problems".
