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 remote presence
function in a single chip.
The IMM supports the following basic systems-management features:
v
Active Energy Manager.
v Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
v
Auto Boot Failure Recovery (ABR).
v
Automatic microprocessor disable on failure and restart in a two-microprocessor
configuration when one microprocessor signals an internal error. When one of
the microprocessors fail, the server will disable the failing microprocessor and
restart with the other microprocessor.
v
Automatic Server Restart (ASR) when POST is not complete or the operating
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 light path diagnostics panel for an
operating-system memory dump. ASR is supported by IPMI.
v
A virtual media key, which enables remote presence support (remote video,
remote keyboard/mouse, and remote storage).
v
Boot sequence manipulation.
v
Command-line interface.
v
Configuration save and restore.
v
DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
disables a failing DIMM that is detected during POST, and the IMM lights the
associated system error LED and the failing DIMM error LED.
v
Environmental monitor with fan speed control for temperature, voltages, fan
failure, power supply failure, and power backplane failure.
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
Intelligent Platform Management Bus (IPMB) support.
v
Invalid system configuration (CONFIG) LED support.
v
Light path diagnostics LEDs indicators to report errors that occur with fans,
power supplies, microprocessor, hard disk drives, and system errors.
v
Local firmware code flash update
v
Nonmaskable interrupt (NMI) detection and reporting.
v
Operating-system failure blue screen capture.
v
PCI configuration data.
v Power/reset control (power-on, hard and soft shutdown, hard and soft reset,
schedule power control).
v
Query power-supply input power.
v
ROM-based IMM firmware flash updates.
v
Serial over LAN (SOL).
v
Serial port redirection over telnet or ssh.
v
SMI handling
v
System event log (SEL) - user readable event log.
