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 control for temperature, voltages, fanfailure, and power supply failure.v Intelligent Platform Management Interface (IPMI) Specification V2.0 andIntelligent Platform Management Bus (IPMB) support.v Invalid system configuration (CNFG) LED support.v Light path diagnostics LEDs to report errors that occur with fans, powersupplies, microprocessor, hard disk drives, and system errors.v Nonmaskable interrupt (NMI) detection and reporting.v Operating-system failure blue screen capture.v PCI configuration data.v PECI 2 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 System-event log.When one of the two microprocessors reports an internal error, the IMM disablesthe defective microprocessor and restarts the server with the one goodmicroprocessor.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 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 standardTelnet client application can access the SOL connection.Obtaining the IP address for the IMM web interface accessTo access the IMM web interface, you need the IP address of the IMM, which youcan obtain through the Setup utility. To obtain the IP address, complete thefollowing steps:1. Turn on the server.2. When the prompt Setup is displayed, press F1. If you have set both apower-on password and an administrator password, you must type theadministrator password to access the full Setup utility menu.Chapter 3. Configuring the server 105
