Non-maskable interrupt switch
Crash dump analysis is an essential part of eliminating reliability problems such as hangs or crashes in operating
systems, device drivers, and applications. Crashes can freeze a system, requiring you to do a hard reset. Resetting
the system erases any information that supports root cause analysis.
Systems running supported Microsoft operating systems experience a blue screen trap when the operating system
crashes. When this happens, Microsoft recommends that system administrators perform a non-maskable interrupt
(NMI) event by pressing a dump switch. The NMI event allows a hung system to become responsive.
The server is equipped with an NMI switch that, when pushed, performs a memory dump before performing a hard
reset.
