Component identification 80
To access the redundant ROM, set S1, S5, and S6 to on.
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 jumper
The NMI jumper 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 OSs,
device drivers, and applications. Many crashes can 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® 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.
Systems Insight Display LEDs
The Systems Insight Display LEDs represent the system board layout. The display provides status for all
internal LEDs and enables diagnosis with the access panel installed. To view the LEDs, access the
