Using the Integrated Management Module 2.1 (IMM2.1)

Integrated Management Module 2.1 (IMM2.1) 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.

IMM2.1 supports the following basic system-management features:

  • Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail)
  • Auto Boot Failure Recovery (ABR)
  • Automatic Server Restart (ASR) when POST is not completed or the operating system hangs and the operating system watchdog timer times out
  • A virtual media key, which enables remote presence support (remote video, remote keyboard/mouse, and remote storage)
  • Boot sequence manipulation
  • Command-line interface
  • Configurations save and restore
  • DIMM error assistance. The UEFI disables a failing DIMM that is detected during POST, and the IMM2.1 lights the associated system error LED
  • Environmental monitor with fan speed control for temperature, voltages, fan failure, power supply failure, and power backplane failure
  • Intelligent Platform Management Interface (IPMI) Specification V2.0 and Intelligent Platform Management Bus (IPMB) support
  • Invalid system configuration (CONFIG) LED support
  • Local firmware code flash update
  • Nonmaskable interrupt (NMI) detection and reporting
  • Operating-system failure blue screen capture
  • PCI configuration data
  • Power/reset control (power-on, hard and soft shutdown, hard and soft reset, schedule power control)
  • Query power-supply input power
  • ROM-based IMM2.1 firmware flash updates
  • Serial over LAN (SOL)
  • Serial port redirection over telnet or ssh protocols
  • SMI handling
  • System event log (SEL) - user readable event log

The IMM2.1 also provides the following remote server management capabilities through the ipmitool, a management utility program:

  • Command-line interface (IPMI Shell)

    The command-line interface provides direct access to server management functions through the IPMI 2.0 protocol. Use the command-line interface to issue commands to control the server power, view system information, and identify the server. You can also save one or more commands as a text file and run the file as a script.

  • Serial over LAN

    Establish a Serial over LAN (SOL) connection to manage servers from a remote location. You can remotely view and change the UEFI settings, restart the server, identify the server, and perform other management functions. Any standard telnet client application can access the SOL connection.
