The ash 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 rmware 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.
