Recovering The Server Firmware - Lenovo ThinkServer TS200 Hardware Maintenance Manual

Recovering the server firmware

Important: Some cluster solutions require specific code levels or coordinated code updates. If the device
is part of a cluster solution, verify that the latest level of code is supported for the cluster solution before
you update the code.
If the server firmware has become corrupted, such as from a power failure during an update, you can
recover the server firmware in one of two ways:
• In-band method: Recover server firmware, using either the boot block jumper (Automated Boot
Recovery) and a server Firmware Update Package Service Pack.
• Out-of-band method: Use the IMM Web Interface to update the firmware, using the latest server
firmware update package.
Notes: You can obtain a server update package from one of the following sources:
• Download the server firmware update from the World Wide Web.
• Contact your Lenovo service representative.
To download the server firmware update package from the World Wide Web, go to
http://www.lenovo.com/support.
The flash memory of the server consists of a primary bank and a backup bank. It is essential that you
maintain the backup bank with a bootable firmware image. If the primary bank becomes corrupted, you can
either manually boot the backup bank with the boot block jumper, or in the case of image corruption, this
will occur automatically with the Automated Boot Recovery function.
In-band manual recovery method
To recover the server firmware and restore the server operation to the primary bank, complete the following
steps:
1. Read the safety information (see "Important Safety Information" on page 1.
2. Turn off the server, and disconnect all power cords and external cables.
3. Unlock and remove the server cover (see "Removing the side cover" on page 142.
4. Locate the UEFI boot recovery jumper (JP6) on the system board (see "System-board switches and
jumpers" on page 132.)
5. Move the jumper from pins 1 and 2 to pins 2 and 3 to enable the UEFI recovery mode.
6. Reinstall the server cover (see "Reinstalling the side cover" on page 201); then, reconnect all power cords.
7. Restart the server. The power-on self-test (POST) starts.
8. Boot the server to an operating system that is supported by the firmware update package that you
downloaded.
9. Perform the firmware update by following the instructions that are in the firmware update package
readme file.
10. Copy the downloaded firmware update package into a directory.
11. From a command line, type filename-s, where filename is the name of the executable file that you
downloaded with the firmware update package.
12. Turn off the server and disconnect all power cords and external cables, and then remove the server cover.
13. Move the UEFI boot recovery jumper back to the primary position (pins 1 and 2).
