Memory Problems; Microprocessor Problems - IBM System x3200 Installation Manual

Memory 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 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 amount of system memory
that is displayed is less than the
amount of installed physical
memory.

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 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.
Action
1. Make sure that:
v No error LEDs are lit on the front-panel assembly or on the system board.
v The memory modules are seated correctly.
v You have installed the correct type of memory.
v If you changed the memory, you updated the memory configuration in the
Configuration/Setup Utility program.
v All DIMMs are enabled. The server might have automatically disabled a
DIMM when it detected a problem.
2. Check the POST error log for error message 289:
v If a DIMM was disabled by a system-management interrupt (SMI), replace
the DIMM.
3. Run memory diagnostics (see "Running the diagnostic programs" in the
Problem Determination and Service Guide on the IBM System x Documentation
CD).
4. Make sure that there is no memory mismatch when the server is over the
minimum memory configuration (one 512 MB DIMM) and that you have
installed the correct number of DIMMs (see the User's Guide on the IBM
System x Documentation CD for information about installing optional memory
modules).
5. Reseat the DIMMs.
6. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. DIMMs
b. (Trained service technician only) System board
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
