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.
