Intermittent problems
Action
A problem occurs only
occasionally and is difficult to
detect.
Verify that:
1. All cables and cords are securely connected to the rear of
the system and to attached options.
2. The last external device in each SCSI chain is terminated
correctly. (Refer to the
User's Reference
on the
IBM xSeries
Documentation
CD more information on SCSI termination.)
If the items above are correct, have the system serviced.
Keyboard, mouse,
or pointing-
device problems
Action
All or some keys on the
keyboard do not work.
Do the following:
1. Verify that the keyboard cable is properly connected to the
system and that the system and the monitor are turned on.
2. Attach another keyboard to the keyboard connector.
If the problem persists, have the system serviced.
The mouse or pointing device
does not work.
Do the following:
1. Verify that the mouse or pointing-device cable is securely
connected.
2. Verify that the device drivers are installed correctly.
3. Attach another mouse or pointing device to the
pointing-device port.
Note:
The pointing-device port is also known as the
auxiliary-device port or mouse port.
If the problem recurs, have the system and the device serviced.
Memory problems
Action
The amount of memory
displayed is less than the
amount of memory installed.
Verify that:
1. The memory modules and memory boards are seated
properly.
2. You have installed the correct type of memory (see
“Installing DIMMs and memory boards” on page 19).
3. If you changed the memory, you must update the
configuration by running the Configuration/Setup Utility
program.
If the above items are correct, run the memory diagnostic
program. The system might have detected a defective
memory module and automatically reallocated memory to
enable you to continue to operate. If the memory tests fail,
have the system serviced or replace the failing DIMM.
