Memory error symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.
Symptom FRU/action
The amount of system memory
displayed is less than the
amount of physical memory
installed.
1. Verify that:
v The memory modules are seated properly.
v
You have installed the correct type of memory.
v
If you changed the memory, you updated the memory configuration with the
Configuration/Setup Utility program.
v
All banks of memory on the DIMMs are enabled. The server might have
automatically disabled a DIMM bank when it detected a problem or a DIMM
bank could have been manually disabled.
2. Check POST error log for error message 289:
v
If the DIMM was disabled by a system-management interrupt (SMI), replace
the DIMM.
v If the DIMM was disabled by the user or by POST:
a. Start the Configuration/Setup Utility program.
b. Enable the DIMM.
c. Save the configuration and restart the server.
3. DIMM.
4. System board.
Microprocessor error symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.
Symptom FRU/action
The server emits a continuous
tone during POST. (The startup
(boot) microprocessor is not
working properly.)
1. Verify that the startup microprocessor is seated properly.
2. (Trained service technician only) Remove microprocessor 2 and restart the
server.
v
If no beep code occurs, microprocessor 2 might have failed; replace the
microprocessor.
v If the beep code remains, remove microprocessor 1 and install
microprocessor 2 in the connector for microprocessor 1; then, restart the
server. If no beep code occurs, microprocessor 1 might have failed; replace
the microprocessor.
3. Startup microprocessor.
Monitor error symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.
Symptom FRU/action
Monitor problems (general). Some IBM monitors have their own self-tests. If you suspect a problem with the
monitor, refer to the information that comes with the monitor for adjusting and
testing instructions.
1. Monitor.
2. Run video diagnostics. If diagnostics pass, the problem may be a video driver.
3. Display adapter / system board.
