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.

Drive numbering
In an 8-bay drive cage, when only one SATA cable is connected, the server can only support a 4-drive
configuration. In this configuration, drive bays 1 through 4 are populated, while drive bays 5 through 8 have
drive blanks.
When the two-port SATA cable option ("
Two-port SATA cable " on page 43 ) is connected, the server supports
a 6-drive configuration. In this configuration, drive bays 1 through 6 are populated, while drive bays 7 and
8 have drive blanks.
