IBM X3850 X6, Installation And Service Manual, Page: 156 / 1730

Note: When one microprocessor fails in a four-microprocessor configuration,
two microprocessors will be disabled.
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 rear of the server for an operating-system
memory dump. ASR is supported by IPMI.
v Remote presence support (remote video, remote keyboard/mouse, and remote
storage).
v
Boot sequence manipulation.
v
Command-line interface.
v
Configuration save and restore.
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
Environmental monitor with fan speed, temperature, voltages, fan failure, power
supply failure, and power backplane failure.
v
First Failure Data Capture (FFDC) support.
v Intelligent Platform Management Interface (IPMI) Specification V2.0 and
Intelligent Platform Management Bus (IPMB) support.
v
Invalid system configuration (CONFIG) LED support.
v
Light path diagnostics LEDs indicators to report errors that occur with fans,
power supplies, microprocessor, hard disk drives, and system errors.
v
Local firmware code flash update
v
Nonmaskable interrupt (NMI) detection, generation, and reporting.
v
Operating-system failure blue screen capture.
v
PCI configuration data.
v PECI 3 support.
v
Power/reset control (power-on, hard and soft shutdown, hard and soft reset,
schedule power control).
v
Query power-supply input power.
v
ROM-based IMM firmware flash updates.
v
Serial over LAN (SOL).
v
Serial port redirection over telnet or ssh.
v
SMI handling
v
System-event log (SEL) - user readable event log.
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
