Starting The Backup Server Firmware; Using The Integrated Management Module - Lenovo System x3650 M5 Installation And Service Manual

Starting the backup server firmware

The system board contains a backup copy area for the server firmware. This is a secondary copy of the
server firmware that you update only during the process of updating the 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 backup
jumper (J15) in the backup position (pins 2 and 3). See "System-board switches, jumpers, and buttons" on
page 34 for the location of the UEFI boot backup jumper (J15).
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 backup jumper (J15) 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 remote presence function in a single chip.
The IMM supports the following basic systems-management features:
• Alerts (in-band and out-of-band alerting, PET traps - IPMI style, SNMP, e-mail).
• Auto Boot Failure Recovery (ABR).
• Automatic microprocessor disable on failure and restart in a two-microprocessor configuration when one
microprocessor signals an internal error. When one of the microprocessors fail, the server will disable the
failing microprocessor and restart with the other microprocessor.
• Automatic Server Restart (ASR) when POST is not complete or the operating system hangs and the
operating system watchdog timer times-out. The IMM might be configured to watch for the operating
system watchdog timer and reboot the system after a timeout, if the ASR feature is enabled. Otherwise,
the IMM allows the administrator to generate a nonmaskable interrupt (NMI) by pressing an NMI button on
the LCD system information display panel (if available) for an operating-system memory dump. ASR is
supported by IPMI.
• A virtual media key, which enables remote presence support (remote video, remote keyboard/mouse, and
remote storage).
• Boot sequence manipulation.
• Command-line interface.
• Configuration save and restore.
• DIMM error assistance. The Unified Extensible Firmware Interface (UEFI) disables a failing DIMM that is
detected during POST, and the IMM lights the associated system error LED and the failing DIMM error
LED.
• Environmental monitor with fan speed control for temperature, voltages, fan failure, power supply failure,
and power backplane failure.
• Intelligent Platform Management Interface (IPMI) Specification V2.0 and Intelligent Platform Management
Bus (IPMB) support.
• Invalid system configuration (CONFIG) LED support.
• LCD system information display panel (if available) reports errors that occur with fans, power supplies,
microprocessor, hard disk drives, and system errors.
• Local firmware code flash update
• Nonmaskable interrupt (NMI) detection and reporting.
• Operating-system failure blue screen capture.
