Using The Integrated Management Module - IBM System x iDataPlex dx360 M3 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 Diagnostic LEDs to report errors that occur with power supplies, microprocessor,
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
v System-event log.
v ROM-based IMM firmware flash updates.
v Auto Boot Failure Recovery.
v A virtual media key, which enables full systems-management support (remote
v When one of the two microprocessors reports an internal error, the server
v NMI detection and reporting.
v SMI handling.
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 redirect.
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.
The IMM also provides the following remote server management capabilities
through the OSA SMBridge management utility program:

configured to watch for the OS watchdog timer and reboot the system after a
timeout, if the ASR feature is enabled. Otherwise, the IMM allows the
administrator to generate an NMI by pressing an NMI button on the system board
for an operating-system memory dump. ASR is supported by IPMI.
