Step 1. Turn off the server.
Step 2. Make sure that the server is cabled correctly.
Step 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 (such as printer, mouse, and non-Lenovo devices.
• Surge-suppressor device (on the server).
• Each adapter.
• Hard disk drives.
Note: The minimum configuration required for the server to start is one microprocessor and one 4
GB DIMM.
Step 4. Turn on the server. If the problem remains, suspect the following components in the following order:
1. Power supply
2. Memory
3. Microprocessor
4. 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 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.
