Non-Maskable Interrupt Switch; System Configuration Settings - HP ML570 - ProLiant - G2 Setup And Installation Manual

Non-Maskable Interrupt Switch

Crash dump analysis is an essential part of determining the cause of problems such as
hangs or crashes in operating systems, device drivers, and applications. Many crashes
freeze a system requiring you to do a hard reset. Resetting the system erases any
information that supports root cause analysis.
When an operating system crashes, system administrators can perform a
non-maskable interrupt (NMI) event by pressing a dump switch. The NMI event
enables a hung system to once again become responsive enough to provide debug
information.
The NMI switch is used ONLY in the event of a service emergency that requires a
complete data dump in preparation for recovering the system from a catastrophic
event.

System Configuration Settings

It may be necessary at some time to clear and reset system configuration settings.
When the system maintenance switch position 6 is set to the on position, the system
is prepared to erase all system configuration settings from both CMOS and NVRAM.
For additional information about locating the switch and switch settings, refer to
"System Maintenance Switch" in this appendix. The default setting for all positions is
off.
IMPORTANT: Clearing CMOS and/or (NVRAM) deletes your configuration information. Refer
to Chapter 8, "Server Configuration and Utilities," for complete instructions on configuring the
server.
