System Maintenance Switch - HP ProLiant ML350 Generation 4 Maintenance And Service Manual

Systems running Microsoft® Windows® operating systems 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 enables a hung system to become responsive again.
