Using The Integrated Management Module - IBM System x3550 M3 Type 4254 Installation And User Manual

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 systems-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,
v Automatic microprocessor disable on failure and restart in a two-microprocessor
v Nonmaskable interrupt (NMI) detection and reporting.
v Automatic Server Restart (ASR) when POST is not complete or the operating
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
v Invalid system configuration (CNFG) LED support.
v Serial port redirection over telnet or ssh.
v Serial over LAN (SOL).
v Active Energy Manager.
v Query power-supply input power.
v PECI 2 support.
v Power/reset control (power-on, hard and soft shutdown, hard and soft reset,
v Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
v Operating-system failure blue screen capture.
v Command-line interface.
v Configuration save and restore.
v PCI configuration data.
v Boot sequence manipulation.

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.
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.
