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 System-event log.v ROM-based IMM firmware flash updates.v Auto Boot Failure Recovery.v A virtual media key, which enables full systems-management support (remotevideo, remote keyboard/mouse, and remote storage).v When one of the two microprocessors reports an internal error, the serverdisables the defective microprocessor and restarts with the one goodmicroprocessor.v NMI detection and reporting.v Automatic Server Restart (ASR) when POST is not complete or the operatingsystem hangs and the OS watchdog timer times out. The IMM might beconfigured to watch for the OS watchdog timer and restart the server after atimeout, if the ASR feature is enabled. Otherwise, the IMM allows theadministrator to generate an NMI by pressing an NMI button on the rear of theserver for an operating-system memory dump. ASR is supported by IPMI.v Intelligent Platform Management Interface (IPMI) Specification V2.0 andIntelligent Platform Management Bus (IPMB) support.v Serial redirect.v Serial over LAN (SOL).v Active Energy Manager.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 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 identify theserver. You can also save one or more commands as a text file and run the fileas a script.v Serial over LANEstablish a Serial over LAN (SOL) connection to manage servers from a remotelocation. You can remotely view and change the UEFI settings, restart the server,identify the server, and perform other management functions. Any standard Telnetclient application can access the SOL connection.98 System x3620 M3 Type 7376: Installation and User’s Guide
