Procedure
1. Turn off the server.
2. Make sure that the server is cabled correctly.
3. Remove or disconnect the following devices, one at a time, until you find the
failure. Turn on the server and reconfigure it each time.
v Any external devices.
v Surge-suppressor device (on the server).
v Printer, mouse, and non-IBM devices.
v Each adapter.
v Hard disk drives.
v Memory modules. The minimum configuration requirement is 2 GB DIMM
in slot 1.
4. Turn on the server.
Results
If the problem is solved when you remove an adapter from the server but the
problem recurs when you reinstall the same adapter, suspect the adapter; if the
problem recurs when you replace the adapter with a different one, suspect the riser
card.
If you suspect a networking problem and the server passes all the system tests,
suspect a network cabling problem that is external to the server.
Problem determination tips
Because of the variety of hardware and software combinations that can encounter,
use the following information to assist you in problem determination. If possible,
have this information available when requesting assistance from IBM.
The model name and serial number are located on the ID label on the front of the
server as shown in the following illustration.
Note: The illustrations in this document might differ slightly from your hardware.
v Machine type and model
v Microprocessor or hard disk drive upgrades
v Failure symptom
– Does the server fail the diagnostic tests?
– What occurs? When? Where?
– Does the failure occur on a single server or on multiple servers?
