See Appendix D, “Getting help and technical assistance,” on page 747 forinformation about calling IBM for service.Recovering the server firmwareUse this information to recover the server firmware.About this taskImportant: Some cluster solutions require specific code levels or coordinated codeupdates. If the device is part of a cluster solution, verify that the latest level ofcode is 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 either 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, go tohttp://www-947.ibm.com/support/entry/portal/overview.The flash memory of the server consists of a primary bank and a backup bank. Youmust maintain a bootable IBM System x Server Firmware (server firmware) imagein 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 inthe case of image corruption, this will occur automatically with the AutomatedBoot Recovery function.In-band manual recovery methodTo recover the server firmware and restore the server operation to the primarybank, complete the following steps:Procedure1. Turn off the server, and disconnect all power cords and external cables.2. Remove the server cover. See “Removing the server top cover” on page 258for more information.3. Locate the UEFI boot recovery jumper (J2) on the system board.150 System x3650 M4 BD Type 5466: Installation and Service Guide
