Switch 2 Default Off 5 Off 6 Off 3, 4, 7, 8, 9, - 10, 11, 12 Function Off = System configuration can be changed On = System configuration is locked Off = Power-on password is enabled On = Power-on password is disabled Off = No function On = ROM reads configuration as invalid 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 header The NMI header enables administrators to perform a memory dump before performing a hard reset. Crash dump analysis is an essential part of eliminating potential reliability issues, such as hangs or crashes in operating systems, device drivers, and applications. Many crashes can freeze a system, requiring you to perform a hard reset. Resetting the system erases any information that supports root cause analysis. Systems running Microsoft® Windows® experience a blue-screen trap when the OS crashes. When this happens, Microsoft® recommends that system administrators perform an NMI event by temporarily shorting the NMI header with a jumper. The NMI event enables a hung system to become responsive again. For additional information, see the HP website (http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00797875/c00797875.pdf).

NMI header
The NMI header enables administrators to perform a memory dump before performing a hard reset. Crash
dump analysis is an essential part of eliminating potential reliability issues, such as hangs or crashes in
operating systems, device drivers, and applications. Many crashes can freeze a system, requiring you to
perform a hard reset. Resetting the system erases any information that supports root cause analysis.
Systems running Microsoft® Windows® experience a blue-screen trap when the OS crashes. When this
happens, Microsoft® recommends that system administrators perform an NMI event by temporarily shorting
