4. The ServerGuide program prompts you to insert your operating-system CDand restart the server. At this point, the installation program for the operatingsystem takes control to complete the installation.Installing your operating system without using ServerGuideUse this information to install the operating system on the server without usingServerGuide.If you have already configured the server hardware and you are not using theServerGuide program to install your operating system, go to http://www.ibm.com/supportportal/ to download the latest operating-system installationinstructions from the IBM website.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 remote presencefunction 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 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 light path diagnostics panel for anoperating-system memory dump. ASR is 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 Managerv Query power-supply input power.v PECI 2 support.122 IBM System x3550 M3 Type 4254 and 7944: Installation and User's Guide
