When the system maintenance switch position 6 is set to the On position, the
system is prepared to erase all system configuration settings from both CMOS
and NVRAM.
CAUTION: Clearing CMOS and/or NVRAM deletes
configuration information. Be sure to properly configure the server or
data loss could occur.
NMI Switch
The NMI switch allows administrators to perform a memory dump before
performing a hard reset. Crash dump analysis is an essential part of eliminating
reliability problems, such as hangs or crashes in operating systems, device
drivers, and applications. Many crashes freeze a system, requiring you to do a
hard reset. Resetting the system erases any information that would support root
cause analysis.
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.
Chassis ID Switch
The chassis ID switch on the system board is reserved for use by authorized
technicians only. Do not modify the switch setting.
