NMI 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 Microsoft
Windows
2000 or 2003 experience a blue screen trap when
the operating system crashes. When this happens, Microsoft recommends that system
administrators perform an NMI event by pressing a dump switch. The NMI event allows a
hung system to become responsive.
The ProLiant BL30p server blade is equipped with an NMI switch that, when pushed,
performs a memory dump before performing a hard reset. The NMI switch is for use by
trained service personnel only.
