Microprocessor Problems; Monitor Or Video Problems - IBM System x3200 Problem Determination And Service 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 Chapter 3, "Parts listing, System x3200 Types 4362 and 4363," on page 67 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 or video 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.
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, System x3200 Types 4362 and 4363," on page 67 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
The screen is blank.
Action
1. Make sure that the microprocessor is supported on this server.
2. (Trained service technician only) Reseat the microprocessor.
3. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. (Trained service technician only) Microprocessor
b. (Trained service technician only) System board
Action
1. Make sure that the monitor cables are firmly connected.
2. Try using a different monitor on the server, or try using the monitor that is being
tested 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. (Trained service technician only) Replace the system board.
1. Make sure that:
v The server is turned on. If there is no power to the server, see "Power
problems" on page 38.
v The monitor cables are connected correctly.
v The monitor is turned on and the brightness and contrast controls are
adjusted correctly.
v A single beep sounds when the server is turned on, indicating the successful
completion of POST.
2. Make sure that the correct server is controlling the monitor, if applicable.
3. Make sure that damaged BIOS code is not affecting the video; see "Recovering
from a BIOS update failure" on page 53.
4. See "Solving undetermined problems" on page 64.
