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 creates a crash dump log before resetting a system which is not responding.
Crash dump log analysis is an essential part of diagnosing reliability problems, such as failures of operating

systems, device drivers, and applications. Many crashes freeze a system, and the only available action for
administrators is to restart the system. Resetting the system erases any information which could support
problem analysis, but the NMI feature preserves that information by performing a memory dump before a

system reset.
To force the system to invoke the NMI handler and generate a crash dump log, do one of the following:

Use the iLO Virtual NMI feature.

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 ("

) 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.
