• Printer, mouse, and non-Lenovo devices.
• Each adapter.
• Hard disk drives.
• Memory modules. The minimum configuration requirement is 2 GB DIMM in slot 1.
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.
