• Hard disk drives.
• Memory modules. The minimum configuration requirement is 2 GB DIMM in slot 3.
The following minimum configuration is required to start the server:
• One microprocessor in socket 1.
• One 2 GB DIMM for each microprocessor installed (one 2 GB DIMM in slot 3 if only one
microprocessor installed).
• One power supply.
• Power cords.
• Five cooling fans (fan 1, 2, 3, 4, and 5).
• One PCI riser-card assembly in PCI connector 2.
• One ServeRAID SAS/SATA controller.
Step 4.
Turn on the server.
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 number 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.

• Machine type and model
• Microprocessor or hard disk drive upgrades
• 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?
– Is the failure repeatable?
– Has this configuration ever worked?
