Using The Integrated Management Module - Lenovo ThinkServer TS200 6522 Hardware Maintenance 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 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 IMM lights the associated system error LED and the failing DIMM
error LED.
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, remote keyboard/mouse,
and remote storage).
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 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.
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 port redirection over Telnet or SSH.
v Serial over LAN (SOL).
v Query power supply input power.
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 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:
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.
