Bridge GUI Guide: Maintenance
195
The Bridge flash memory is partitioned into two, bootable
image areas. The software upgrade file is written to the non-
running partition—i.e., the partition that does
not
contain the
software currently running on the Bridge. The upgrade does
not therefore take effect until the Bridge is rebooted (as
described in Section 6.1.2), and the currently running software
is retained on the partition it was originally written to.
The software image on a given flash partition cannot be
downgraded, and you should not overwrite an image with an
earlier version of the software. You can, however, revert to the
earlier version of the software even after you have upgraded
and rebooted the Bridge (refer to Section 6.1.2).

from the upgraded par-

grade while the Bridge is

. Revert to the
previous software ver-
sion before retrying the
upgrade.
