Starting The Backup Server Firmware; Using The Integrated Management Module - IBM x3250 M3 Problem Determination And Service Manual

The next time the server starts, it returns to the startup sequence that is set in the
Setup utility.

Starting the backup server firmware

The system board contains a backup copy area for the server firmware (formerly
BIOS firmware). This is a secondary copy of the server firmware that you update
only during the process of updating the 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
JP6 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 JP6 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 an optional
virtual media key 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 Light path diagnostics LEDs indicators to report errors that occur with fans,
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
v System-event log (SEL).
v ROM-based IMM firmware flash updates.
v Auto Boot Failure Recovery (ABR).
v A virtual media key, which enables remote presence support (remote video,

system hangs and the operating system watchdog timer times-out. The IMM
might be configured to watch for the operating system watchdog timer and reboot
the system after a timeout, if the ASR feature is enabled. Otherwise, the IMM
allows the administrator to generate a nonmaskable interrupt (NMI) by pressing
an NMI button on the system board for an operating-system memory dump. ASR
is supported by IPMI.
