Component identification 95
Position Default Function
S5 Off Off = Power-on password is enabled.
On = Power-on password is disabled.
S6 Off Off = Normal
On = ROM treats system configuration as invalid.
S7 Off Reserved
S8 Off Reserved
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 functionality
An NMI crash dump enables administrators to create crash dump files when a system is hung and not
responding to traditional debug mechanisms.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as hangs in
operating systems, device drivers, and applications. Many crashes freeze a system, and the only
available action for administrators is to cycle the system power. Resetting the system erases any
information that could support problem analysis, but the NMI feature preserves that information by
performing a memory dump before a hard reset.
To force the OS to invoke the NMI handler and generate a crash dump log, the administrator can do any
of the following:
• Short the NMI jumper pins
• Press the NMI switch
• Use the iLO Virtual NMI feature
