The next time the server starts, it returns to the startup sequence that is set in theSetup utility.Starting the backup server firmwareThe system board contains a backup copy area for the server firmware (formerlyBIOS firmware). This is a secondary copy of the server firmware that you updateonly during the process of updating the server firmware. If the primary copy of theserver firmware becomes damaged, use this backup copy.To force the server to start from the backup copy, turn off the server; then, place theJP6 jumper in the backup position (pins 2 and 3).Use the backup copy of the server firmware until the primary copy is restored. Afterthe primary copy is restored, turn off the server; then, move the JP6 jumper back tothe primary position (pins 1 and 2).Using the integrated management moduleThe integrated management module (IMM) is a second generation of the functionsthat were formerly provided by the baseboard management controller hardware. Itcombines service processor functions, video controller, and (when an optionalvirtual media key is installed) remote presence function in a single chip.The IMM supports the following basic system management features:v Environmental monitor with fan speed control for temperature, voltages, fanfailure, and power supply failure.v Light path diagnostics LEDs indicators to report errors that occur with fans,power supplies, microprocessor, hard disk drives, and system errors.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 (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 Automatic microprocessor disable on failure and restart in a two-microprocessorconfiguration when one microprocessor signals an internal error.v Nonmaskable interrupt (NMI) detection and reporting.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 and rebootthe system after a timeout, if the ASR feature is enabled. Otherwise, the IMMallows the administrator to generate a nonmaskable interrupt (NMI) by pressingan NMI button on the system board for an operating-system memory dump. ASRis supported by IPMI.v Intelligent Platform Management Interface (IPMI) Specification V2.0 andIntelligent 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 Active Energy Manager (AEM).Chapter 6.
