Starting the backup server firmware
This topic provides instructions on starting the backup copy of the server firmware in the event that the primary copy of the firmware becomes damaged or corrupt.
The standard I/O book board contains a backup copy area for the server firmware. This is a secondary copy of the server firmware that you update only during the process of updating the server firmware. If the primary copy of the server firmware becomes damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, change the position of switch 7 on the SW1 switch block to ON. See Jumpers, switches, and buttons on standard I/O book board for more information about the jumpers, switches, and buttons on the server. The following illustration shows the location of the SW1 switch block.

Use the backup copy of the server firmware until the primary copy is restored. After the primary copy is restored, turn off the server; then, change the position of switch 7 back to OFF (the default).
