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
failure, power supply failure, and power backplane failure.
v
LED indicators to report errors that occur with fans, power supplies,
microprocessor, hard disk drives, and system errors (EasyLED Diagnostics)
v
DIMM error assistance. The Unified Extensible Firmware Interface (UEFI) will
disable a failing DIMM that is detected during POST IMM will light the associated
system-error LED and the failing DIMM error LED.
v
System-event log (SEL)
v
ROM-based IMM firmware flash (IMM firmware updates)
v
Auto Boot Failure Recovery (ABR)
v
A virtual media key which enables full system management support (remote
video, remote keyboard/mouse, and remote storage)
v
Automatic microprocessor disable on failure restart in a two-microprocessor
configuration when one microprocessor signals an internal error
v
NMI detection and reporting
v
SMI handling
v
Automatic Server Restart (ASR) when (1) POST is not complete or (2) the OS
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.
v
Intelligent Platform Management Interface (IPMI) Specification V 2.0 and
Intelligent Platform Management Bus (IPMB) support
v
Invalid system configuration (CNFG) LED support
v
Serial redirect
v
Serial Over LAN (SOL)
v
Query power supply input power
v
PECI 2 support
