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:

vEnvironmental monitor with fan speed control for temperature, voltages, fan failure, and power supply failure.

vEasyLED indicators to report errors that occur with fans, power supplies, microprocessor, hard disk drives, and system errors.

vDIMM 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.

vSystem-event log (SEL).

vROM-based IMM firmware flash updates.

vAuto Boot Failure Recovery (ABR).

vA virtual media key, which enables remote presence support (remote video, remote keyboard/mouse, and remote storage).

vAutomatic 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.

vNonmaskable interrupt (NMI) detection and reporting.

vAutomatic 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 system board for an operating-system memory dump. ASR is supported by IPMI.

vIntelligent Platform Management Interface (IPMI) Specification V2.0 and Intelligent Platform Management Bus (IPMB) support.

vSerial port redirection over telnet or ssh.

vSerial over LAN (SOL).

vActive Energy Manager.

vQuery power-supply input power.

vPECI 2 support.

vPower/reset control (power-on, hard and soft shutdown, hard and soft reset, schedule power control).

vAlerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).

vOperating-system failure blue screen capture.

vCommand-line interface.

vConfiguration save and restore.

vPCI configuration data.
