Non-Maskable Interrupt Switch (NMI)

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. Refer to Figure E-6 for location of the NMI switch.
