Symptom FRU/action
System stops responding during

1. Remove the hard disk drive being tested when the server stopped
responding and try the diagnostic test again.
2. If the hard disk drive diagnostic test runs successfully, replace the drive you

Intermittent error symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.
Symptom FRU/action
A problem occurs only
occasionally and is difficult to
detect.
1. Verify that:
v
All cables and cords are connected securely to the rear of the server and
attached options.
v
When the server is turned on, air is flowing from the rear of the server at the
fan grill. If there is no airflow, the fan is not working. This causes the server
to overheat and shut down.
v
Ensure that the SCSI bus and devices are configured correctly and that the
last external device in each SCSI chain is terminated correctly.
2. Check the system error log.
3. See “Undetermined problems” on page 119.
Keyboard, mouse, or pointing device error symptoms
Note: See “System replaceable units” on page 122 to determine which components should be replaced by a field
service technician.

keyboard do not work.
1. See http://www.ibm.com/servers/eserver/serverproven/compat/us/ for keyboard

The keyboard cable is securely connected to the system, and the keyboard
and mouse cables are not reversed.
