• If the factory default switch is pressed and held for 70 seconds, a default configuration will
overwrite your existing configuration and reboot the unit. When the default configuration is
being applied, the STAT, WAN, DBU, and VPN LEDs will cycle. At this point, the default
switch can be released.
For more information on restoring factory defaults, refer to the guide
Factory Default available online at https://supportforums.adtran.com.
To factory default the unit, the default switch must be pressed WHILE the
STAT light on the front of the unit is solid green. Do not press the default
switch BEFORE the STAT light is solid green, as this will cause boot to be
missed.
