Starting The Backup Server Firmware - IBM System x3850 X6 Installation And Service Manual

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.
About this task
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" on page 39 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).
