System Switches
NMI button (SW5)
If the system crashes or stops operating, you can momentary press the NMI button (SW5) to manually
force the server to issue a Non-Maskable Interrupt (NMI). This will perform a memory dump—writing
the contents in the server's CPU registers and system memory to a network server or to diskettes. This
memory dump can later be analyzed to determine the cause of the problem. By default, the NMI
switch is always disabled.
