Solving undetermined problems
If Dynamic System Analysis (DSA) cannot diagnose the failure or if the server is inoperative, use the information in this section to solve the undetermined problems.
If you suspect that a software problem is causing failures (continuous or intermittent), see Software problems.
Corrupted data in CMOS memory or corrupted UEFI firmware can cause undetermined problems. To reset the CMOS data, use the CMOS clear jumper (JP1) to clear the CMOS memory and override the power-on password; see System-board internal connectors for more information. If you suspect that the UEFI firmware is corrupted, see Recovering the server firmware (UEFI update failure).
If the power supplies are working correctly, complete the following steps:
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.
