If you suspect that a software problem is causing failures (continuous or intermittent), see “Software
problems” on page 65.
Damaged data in CMOS memory or damaged server firmware can cause undetermined problems. To reset
the CMOS data, use the clear CMOS jumper to clear the CMOS memory. If you suspect that the server
firmware is damaged, see “Recovering the server firmware” on page 307.
Check the LEDs on all the power supplies. If the LEDs indicate that the power supplies are working
correctly, complete the following steps:
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.
• Any external devices.
• Surge-suppressor device (on the server).
• Modem, printer, mouse, and non-Lenovo devices.
• Each adapter.
• Hard disk drives.
• Memory modules. The minimum configuration requirement is two 1 GB DIMM on the system board.
The following minimum configuration is required for the server to start:
• One microprocessor
• One 1 GB DIMM on the system board
• One power supply
• Power cord
• ServeRAID SAS/SATA adapter
• System board
4. Turn on the server. If the problem remains, suspect the following components in the following order:
a. Memory module
b. Microprocessor
c. System board
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 system board.
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 you can encounter, use the following
information to assist you in problem determination. If possible, have this information available when you
request assistance from Lenovo.
• Machine type and model
• Microprocessor and hard disk drive upgrades
• Failure symptoms
– Does the server fail the diagnostic programs? If so, what are the error codes?
– What occurs? When? Where?
– Does the failure occur on a single server or on multiple servers?
– Is the failure repeatable?
