Recovering the server firmware

Use this information to recover 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 either 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

The flash memory of the server consists of a primary bank and a backup bank. You must maintain a bootable
Lenovo System x Server Firmware (server firmware) image in the backup bank. If the server firmware in 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:
Step 1. Turn off the server, and disconnect all power cords and external cables.
Step 2. Remove the server cover. See "Removing the left-side cover" on page 193 for more information.
Step 3. Locate the UEFI boot backup jumper (J2) on the system board.
