System administration
When the device reboots, it will attempt to use the current firmware version. If the current firmware
version fails to load after three consecutive attempts, it is marked as invalid and the device will use
the previous firmware version stored in the alternate memory bank.
If the device consistently looses power during the boot process, this may result in the current
firmware being marked as invalid and the device downgrading to a previous version of the firmware.
As a result of this behavior, you can use the following procedure to guarantee that the same firmware
is stored in both memory banks:
WebUI

Command line
1. Log into the Connect EZ command line as a user with Admin access.
