v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
trained service technician.
Symptom Action
The mouse or pointing device
does not work.
1. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it
as a possible cause of the problem: connect the mouse or pointing-device
cable directly to the correct connector on the rear of the server.
2. Make sure that:
v The mouse or pointing-device cable is securely connected and the keyboard
and mouse cables are not reversed.
v The mouse device drivers are installed correctly.
v The mouse is enabled in the Configuration/Setup Utility program.
3.
Reseat the mouse or pointing device cable.
4. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. Mouse or pointing device
b. (Trained service technician only) System board

The amount of system memory
that is displayed is less than the
amount of installed physical
memory.
1. Make sure that:
v No error LEDs are lit on the operator information panel.
v The memory modules are seated correctly.
v You have installed the correct type of memory (see “Installing a memory
module” on page 9).
v All banks of memory are enabled. The server might have automatically
disabled a memory bank when it detected a problem.
2.
Check the POST error log for error message 289 (see “Using the
Configuration/Setup Utility program” on page 26); if a DIMM was disabled by a
system-management interrupt (SMI), replace the DIMM.
3. Run memory diagnostics (see “Running the diagnostic programs” in the
Problem Determination and Service Guide).
4. Add one pair of DIMMs at a time, making sure that the DIMMs in each pair
match.
5. Reseat the DIMMs.
6. Replace the following components one at a time, in the order shown, restarting
the server each time:
