Restoring Factory Defaults on an Adtran TA900

RESTORING FACTORY DEFAULTS
On units that have a console port, you cannot restore the factory defaults, but must rather erase the device’s
configuration and then reconfigure the unit to operate correctly for your network. To erase the unit’s current
configuration, follow these steps:
  1. Access the unit’s CLI and enter enable at the >prompt.
  2. Enter erase startup-config at the # prompt. The device will have a blank configuration upon reboot.
  3. Enter reload at the # prompt to begin restarting the device. When prompted to save configuration, enter no . When prompted to reboot, enter yes .
  4. Upon reboot, you will have to reconfigure the unit using the CONSOLE port. Follow the steps outline here or in the technical note, Accessing the Web Interface in AOS, available online at http://kb.adtran.com.
