Starting the backup server firmware

The system board contains a backup copy area for the server firmware. This is a
secondary copy of server firmware that you update only during the process of
updating server firmware. If the primary copy of the server firmware becomes
damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, place the
UEFI boot recovery J29 jumper in the backup position (pins 2 and 3).
Use the backup copy of the server firmware until the primary copy is restored. After
the primary copy is restored, turn off the server; then, move the UEFI boot recovery
J29 jumper back to the primary position (pins 1 and 2).

Using the Integrated Management Module

The Integrated Management Module (IMM) is a second generation of the functions
that were formerly provided by the baseboard management controller hardware. It
combines service processor functions, video controller, and (when IMM Premium is
installed) remote presence function in a single chip.
The IMM supports the following basic system management features:
v Environmental monitor with fan speed control for temperature, voltages, fan
v LED indicators to report errors that occur with fans, power supplies,
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI) will

hangs and the OS Watchdog Timer times-out. The IMM might be configured to
watch for OS Watchdog Timer and reboot the system after timeout, if the ASR
feature is enabled. Otherwise, IMM allows the administrator to generate an NMI
by pressing an NMI button on the system board for OS memory dump. ASR is
supported by IPMI.
