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, do the following:
1. Read the safety information (see “Safety” on page vii, “Handling static-sensitive
devices” on page 39, and “Working inside the server with the power on” on
page 38).
2. Turn off the server, and disconnect all power cords and external cables.
