For more information about the IMM2, see the Integrated Management Module II
User's Guide at http://www-947.ibm.com/support/entry/portal/
docdisplay?brand=5000008&lndocid=MIGR-5086346.
The IMM2 supports the following basic systems-management features:
v Environmental monitor with fan speed control for temperature, voltages, fan
failure, and power supply failure.
v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)
disables a failing DIMM that is detected during POST, and the IMM2 lights the
associated system error LED and the failing DIMM error LED.
v System-event log (SEL).
v ROM-based IMM2 firmware flash updates.
v Auto Boot Failure Recovery (ABR).
v Nonmaskable interrupt (NMI) detection and reporting.
v Automatic Server Restart (ASR) when POST is not complete or the operating
system hangs and the operating system watchdog timer times-out. The IMM2
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 IMM2
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.
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
Intelligent Platform Management Bus (IPMB) support.
v Invalid system configuration (CNFG) LED support.
v Serial over LAN (SOL).
v PECI 2 support.
v Power/reset control (power-on, hard and soft shutdown, hard and soft reset,
schedule power control).
v Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
v Operating-system failure blue screen capture.
v Configuration save and restore.
v PCI configuration data.
v Boot sequence manipulation.
The IMM2 also provides the following remote server management capabilities
through the OSA SMBridge management utility program:
v 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.
v 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.
