NMI button (SW4)
If the system crashes or stops operating properly, you can use the NMI button (SW4) to mechanically
force the server to issue a non-maskable interrupt. This will perform a memory dump—writing the
contents of the server's CPU registers and RAM 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
enabled.

NOTE: Use of the NMI button is not supported in all NOS. As of the present, NMI implementation is
not available for systems running on Solaris and Linux operating systems.
