Lenovo 3821, 3822 Starting the backup server firmware, Using the Integrated Management Module

Starting the backup server firmware

The system board contains a backup copy area for the server firmware. This is a secondary copy of server firmware that you update only during the process of updating server firmware. If the primary copy of the server firmware becomes damaged, use this backup copy.

To force the server to start from the backup copy, turn off the server; then, place the UEFI boot recovery J29 jumper in the backup position (pins 2 and 3).

Use the backup copy of the server firmware until the primary copy is restored. After the primary copy is restored, turn off the server; then, move the UEFI boot recovery J29 jumper back to the primary position (pins 1 and 2).

Using the Integrated Management Module

The Integrated Management Module (IMM) is a second generation of the functions that were formerly provided by the baseboard management controller hardware. It combines service processor functions, video controller, and (when IMM Premium is installed) remote presence function in a single chip.

The IMM supports the following basic system management features:

vEnvironmental monitor with fan speed control for temperature, voltages, fan failure, power supply failure, and power backplane failure.

vLED indicators to report errors that occur with fans, power supplies, microprocessor, hard disk drives, and system errors (EasyLED Diagnostics LEDs)

vDIMM error assistance. The Unified Extensible Firmware Interface (UEFI) will disable a failing DIMM that is detected during POST IMM will light the associated system-error LED and the failing DIMM error LED.

vSystem-event log (SEL)

vROM-based IMM firmware flash (IMM firmware updates)

vAuto Boot Failure Recovery (ABR)

vA virtual media key which enables full system management support (remote video, remote keyboard/mouse, and remote storage)

vAutomatic microprocessor disable on failure restart in a two-microprocessor configuration when one microprocessor signals an internal error

vNMI detection and reporting

vSMI handling

vAutomatic Server Restart (ASR) when (1) POST is not complete or (2) the OS hangs and the OS Watchdog Timer times-out. The IMM might be configured to watch for OS Watchdog Timer and reboot the system after timeout, if the ASR feature is enabled. Otherwise, IMM allows the administrator to generate an NMI by pressing an NMI button on the system board for OS memory dump. ASR is supported by IPMI.

vIntelligent Platform Management Interface (IPMI) Specification V 2.0 and Intelligent Platform Management Bus (IPMB) support

vInvalid system configuration (CNFG) LED support

vSerial redirect

vSerial Over LAN (SOL)

vQuery power supply input power

vPECI 2 support
