Recovering the server firmwareImportant: Some cluster solutions require specific code levels or coordinated codeupdates. If the device is part of a cluster solution, verify that the latest level of codeis supported for the cluster solution before you update the code.If the server firmware has become corrupted, such as from a power failure duringan update, you can recover the server firmware in one of two ways:v In-band method: Recover server firmware, using either the boot block jumper(Automated Boot Recovery) and a server Firmware Update Package ServicePack.v Out-of-band method: Use the IMM Web Interface to update the firmware, usingthe latest server firmware update package.Note: You can obtain a server update package from one of the following sources:v Download the server firmware update from the World Wide Web.v Contact your IBM service representative.To download the server firmware update package from the World Wide Web,complete the following steps.Note: Changes are made periodically to the IBM Web site. The actual proceduremight vary slightly from what is described in this document.1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Software and device drivers.4. Click System x3550 M3 to display the matrix of downloadable files for theserver.5. Download the latest server firmware update.The flash memory of the server consists of a primary bank and a backup bank. It isessential that you maintain the backup bank with a bootable firmware image. If theprimary bank becomes corrupted, you can either manually boot the backup bankwith the boot block jumper, or in the case of image corruption, this will occurautomatically with the Automated Boot Recovery function.In-band manual recovery methodTo recover the server firmware and restore the server operation to the primarybank, complete the following steps:1. Turn off the server, and disconnect all power cords and external cables.2. Remove the server cover. See “Removing the cover” on page 174 for moreinformation.3. Locate the UEFI boot recovery jumper block (J29) on the system board.152 IBM System x3550 M3 Types 4254 and 7944: Problem Determination and Service Guide
