Before distributing the firmware update to other servers, ensure that your server can restart successfully
without encountering hardware problems.
Starting the backup server firmware
The system 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, place the JP6 jumper in the
backup position (pins 2 and 3).
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, move the JP6 jumper back to the primary position (pins 1 and 2).

If the UEFI firmware has become damaged, such as from a power failure during an update, you can recover
the UEFI firmware using the boot block jumper and a UEFI recovery diskette.
