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 operatingsystem hangs and the operating system watchdog timer times out. The IMMmight be configured to watch for the operating system watchdog timer andreboot the system after a timeout, if the ASR feature is enabled. Otherwise, theIMM allows the administrator to generate a nonmaskable interrupt (NMI) bypressing an NMI button on the rear of the server for an operating-systemmemory dump. ASR is supported by IPMI.v Remote presence support (remote video, remote keyboard/mouse, and remotestorage).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 theassociated system error LED and the failing DIMM error LED.v Environmental monitor with fan speed, temperature, voltages, fan failure, powersupply failure, and power backplane failure.v First Failure Data Capture (FFDC) support.v Intelligent Platform Management Interface (IPMI) Specification V2.0 andIntelligent 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 updatev 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 handlingv System-event log (SEL) - user readable event log.The IMM also provides the following remote server management capabilitiesthrough the OSA SMBridge management utility program:v Command-line interface (IPMI Shell)The command-line interface provides direct access to server managementfunctions through the IPMI 2.0 protocol. Use the command-line interface to issuecommands to control the server power, view system information, and identifythe server. You can also save one or more commands as a text file and run thefile as a script.v Serial over LAN138 System x3850 X6 and x3950 X6 Types 3837 and 3839: Installation and Service Guide
