Memory problems
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 with the
Configuration/Setup Utility program.
4.
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.
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.
The amount of memory
displayed is less than the
amount of memory installed.
Microprocessor problems
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.
The server emits a continuous
tone during POST.
Monitor
Some IBM monitors have their own self-tests. If you suspect a problem with your
monitor, refer to the information that comes with the monitor for adjusting and
testing instructions.
If you still cannot find the problem, call for service.

The screen is blank.
Verify that:
1.
The server power cords are plugged into the server and a working electrical
outlet.
2.
The monitor cables are connected properly.
3.
The monitor is turned on and the Brightness and Contrast controls are adjusted
correctly.
If the items above are correct and the screen remains blank, call for service.

The monitor works when you
turn on the server, but goes
blank when you start some
application programs.
Verify that:
1.
The primary monitor cable is connected to the video port.
2.
You installed the necessary device drivers for the applications.
If the items above are correct and the screen remains blank, call for service.
