IBM xSeries 350: Installation Guide
Power problems Suggested action
The server does not power on. Verify that:
1. The power cables are properly connected to the server.
2. The electrical outlet functions properly.
3. The type of memory that is installed is correct.
4. If you just installed an option, remove it, and restart the server. If the server
now powers on, you might have installed more options than the power supply
can support.
5. The LEDs on the power supply are on.
If the problem remains, call for service.
Microprocessor problems Suggested action
The server emits a continuous
tone during POST. The startup (boot) microprocessor is not working properly.
Verify that the startup microprocessor is seated properly. If it is, replace the startup
microprocessor.
If the problem remains, call for service.
Memory problems Suggested action
The amount of memory
displayed is less than the
amount of memory installed. Verify that:
1. The memory modules are seated properly.
2. You have installed the correct type of memory.
3. If you changed the memory, you updated the memory configuration using the
Configuration/Setup Utility program.
4. All banks of memory on the DIMMs are enabled. The server might have
detected a problem and automatically disabled a DIMM bank, or a DIMM bank
could have been manually disabled.
If the above items are correct, run the memory-diagnostic program. The system
might have detected a bad memory module and automatically reallocated memory
to enable you to continue to operate. If the memory tests fail, call for service or
replace the failing DIMM.
