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 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 BL20p G2 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.
System Configuration Switch Procedures
When you perform troubleshooting steps, this guide may instruct you to perform the
following procedures:
•
