Non-Maskable Interrupt (NMI) button—This section contains the Generate NMI to System
button, which enables you to stop the operating system for debugging. The Virtual Power and
Reset privilege is required to generate an NMI.
CAUTION:
Generating an NMI as a diagnostic and debugging tool is used primarily when
the operating system is no longer available. NMI is not used during normal operation of the
server. Generating an NMI does not gracefully shut down the operating system, but causes
the operating system to crash, resulting in lost service and data. Use the Generate NMI to
System button only in extreme cases in which the operating system is not functioning properly
and an experienced support organization has recommended that you proceed with an NMI.
Note the following:
◦
Use the Debug feature if a software application hangs the system. Use the Generate NMI
to System button to engage the operating system debugger.
◦
Initiate the dump of an unresponsive host if you want to capture the server context.
•
Redundant ROM Support—You can safely upgrade or configure the server ROM with redundant
ROM support.
◦
The Active ROM table shows the current version and the release date of the system ROM
on the local machine.
◦
The Backup ROM table shows the release date of the backup ROM and the release date
of the backup ROM bootblock. The backup ROM is typically the previously installed
version.
Click the Swap ROM button to swap the active ROM and backup ROM. The change will take
effect after the next system reboot.
Resetting iLO through the web interface

Using Location Discovery Services
Location Discovery Services is a component of HP Discovery Services. Location Discovery Services
automatically reports server locations to HP SIM and Insight Control, eliminating this manual task
for server administrators. Administrators can use the location information and system data with HP
Asset Manager to obtain more precise and complete asset data.
Location Discovery Services is a rack U location discovery solution for G3 and later racks. It enables
HP iLO, BL Onboard Administrator, and SL Chassis firmware to report and display the rack ID and
the server U position in the rack. Supported racks are programmed with unique U values in 7U
and/or 8U modules, and are installed with the tag version number, rack identifier, part number,
product name, rack height, and U position. Location Discovery Services supports 14U, 22U, 36U,
42U, and 47U racks.
The rack device reads the rack U location tag each time iLO receives AC power or iLO is reset.
The U position value denotes the U position read by the device. The contact position offset is a
