Intermittent problems
v
Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v
See Chapter 3, “Parts listing,” on page 59 to determine which components are customer replaceable units
(CRU) and which components are field replaceable units (FRU).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
A problem occurs only
occasionally and is difficult to
diagnose.
1. Make sure that:
v
All cables are connected securely to the front of the system-board tray and
the power cord is connected securely to the rear of the chassis.
v
When the system-board tray is turned on, air is flowing from the rear of the
chassis. If there is no airflow, the fan assembly is not working. This causes
the system-board tray to overheat and shut down.
2. Check the BMC system event log (see “Error logs” on page 18).
3. See “Solving undetermined problems” on page 57.
