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.
