Microprocessor Problems; Monitor Problems - IBM x3550 - System - 7978 Installation Manual

Microprocessor 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 the parts listing in the Problem Determination and Service Guide on the IBM System x Documentation
CD 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
The server emits a continuous
beep during POST, indicating
that the startup (boot)
microprocessor is not working
correctly.

Monitor problems

Some IBM monitors have their own self-tests. If you suspect a problem with your
monitor, see the documentation that comes with the monitor for instructions for
testing and adjusting the monitor. If you cannot diagnose the problem, call for
service.

CD 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
Testing the monitor
Action
1. Correct any errors that are indicated by the light path diagnostics LEDs (see
"Light path diagnostics" on page 68).
2. Make sure that the server supports the microprocessor.
3. (Trained service technician only) Make sure that the microprocessor is seated
correctly.
4. (Trained service technician only) Replace the microprocessor.
Action
1. Make sure that the monitor cables are firmly connected.
2. Try using a different monitor on the server, or try testing the monitor on a
different server.
3. Run the diagnostic programs. If the monitor passes the diagnostic programs,
the problem might be a video device driver.
4. Reseat the Remote Supervisor Adapter II SlimLine (if one is present).
5. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. Remote Supervisor Adapter II SlimLine (if one is present).
b. (Trained service technician only) System board.
