Troubleshooting charts
The following tables list problem symptoms and suggested solutions. See the
Problem Determination and Service Guide for your blade server type for more
detailed troubleshooting charts. If you cannot find the problem in these charts, run
the diagnostic programs. If you have run the diagnostic test programs, or if running
the tests does not reveal the problem, call for service.
Memory problems
Symptom Suggested action
The amount of system
memory displayed is less
than the amount of physical
memory installed.
Make sure that:
v
The DIMMs 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 banks of memory are enabled. The blade server might have automatically
disabled a memory bank when it detected a problem, or a memory bank might
have been manually disabled.
Check the 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 DIMMs are not installed in pairs, install the DIMMs starting with DIMM 1 and
DIMM 2. Make sure that there is not an unpopulated DIMM slot in the middle or
that DIMM 3 and DIMM 4 are installed before DIMM 1 and DIMM 2.
v
If the system halts, make sure that the DIMMs installed in each pair are the same
size, speed, type, technology, and physical design. Swap DIMM 3 and DIMM 4
with DIMM 1 and DIMM 2.
v
If the system error is an unsupported memory configuration, make sure that there
is more than one DIMM installed. Install DIMMs in DIMM slots 1 and 2. If this does
not fix the error, replace the DIMMs flagged in the management module log and
indicated through light path diagnostics LEDs.
v If the DIMM was disabled by the user or by POST, run the Configuration/Setup
Utility program and enable the DIMM.
v If this error remains, replace the DIMM.
If the problem remains, call for service.
Microprocessor problems
Symptom Suggested action
The blade server emits a
continuous tone during POST.
The startup (boot) microprocessor is not working correctly.
The startup microprocessor might not be seated correctly, call for service.
