Automated Boot Recovery (Abr); Three Boot Failure; Using The Integrated Management Module - Lenovo TD200 - ThinkServer - 3809 Hardware Maintenance Manual

1. Boot the server to an operating system that is supported by the firmware update package that you
downloaded.
2. Perform the firmware update by following the instructions that are in the firmware update package
readme file.
3. Restart the server.
4. At the firmware splash screen, press F3 when prompted to restore to the primary bank. The server
boots from the primary bank.
Out-of-band method: See the IMM documentation.

Automated boot recovery (ABR)

If the server is booting up and the IMM detects problems with the server firmware in the primary bank, it will
automatically switch to the backup firmware bank and give you the opportunity to recover the primary bank.
To recover to the server firmware primary bank, complete the following steps:
Step 1. Restart the server.
When the prompt press F3 to restore to primary is displayed, press F3 to recover the primary bank.
Step 2.
Pressing F3 will restart the server.

Three boot failure

Configuration changes, such as added devices or adapter firmware updates can cause the server to fail
POST (power-on self-test). If this occurs on three consecutive boot attempts, the server will temporarily uses
the default configuration values and automatically goes to F1 Setup. To solve the problem, complete the
following steps:
Step 1. Undo any configuration changes that you made recently and restart the server.
Step 2. Remove any devices that you added recently and restart the server.
Step 3. If the problem remains, go to the Setup utility and select Load Default Settings, and then click
Save to restore the server factory settings.

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 an optional virtual media key is installed) remote presence function in a single chip.
The IMM supports the following basic systems-management features:
• Environmental monitor with fan speed control for temperature, voltages, fan failure, and power supply
failure.
• EasyLED diagnostics LEDs indicators to report errors that occur with fans, power supplies,
microprocessor, hard disk drives, and system errors.
• 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.
• System event log (SEL).
• ROM-based IMM firmware flash updates.
• Auto Boot Failure Recovery (ABR).
