If the NMI indicator is lit, and the system has recovered from the hardware error based on the system log, clear alarms by using the following methods:
Remove AC PSUs from the server, shut down the system, and wait for 15 minutes. Then restart the server.
Reinstall devices (including PCIe devices and the memory) that are inclined to cause the hardware error.
Delete alarm logs that cause NMI alarms from the system log.
If the NMI alarm indicator is lit, and the MIM or PCI alarm indicator is also lit, resolve the problem based on the prompt information on the MEM or PCI indicator.
