Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are
replaceable by the customer and which components must be replaced by an IBM field service technician.
Symptom
The amount of system memory
displayed is less than the
amount of physical memory
installed.
Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are
replaceable by the customer and which components must be replaced by an IBM field service technician.
Symptom
The server emits a continuous
tone during POST. (The startup
(boot) microprocessor is not
working properly.)
Note: See Chapter 7, "Parts listing, Types 8861, 8862," on page 139 to determine which components are

Symptom
Testing the monitor.
Memory problems
FRU/action
1. Verify that:
v No error LEDs are lit on the operator information panel or in the memory
cassette.
v Memory mirroring does not account for the mismatch.
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 are enabled. The server might have automatically
disabled a memory bank when it detected a problem, or a memory bank
might 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 computer.
3. DIMM.
4. Memory cassette[
Microprocessor problems
FRU/action
1. Verify that the startup microprocessor is seated correctly.
2. Startup microprocessor.
3. Microprocessor VRM 3 or 4.
4. Microprocessor tray assembly.
Monitor problems
FRU/action
See the information that comes with the monitor for adjusting and testing
instructions. (Some IBM monitors have their own self-tests.)
1. Monitor.
2. Run diagnostic programs. If diagnostic programs pass, the problem may be a
video driver.
3. Remote Supervisor Adapter II.
4. I/O board.
