Re: reset TA 904 to factory defaults

The default configuration isn't stored on the device, so it isn't trivial to get it to factory defaults. It's a three-step process. Access the unit, erase the old configuration, and upload the default file.

1. Access the unit without a password:

  • Connect a terminal emulator to the console port, set to 9600 baud, N,8,1.
  • Power-cycle the unit and hit the ESCAPE key when it starts to boot. You may have to do this a few times at about one-second intervals.  The router should come up in bootstrap mode.
  • Type bypass passwords and hit ENTER.
  • Type boot and hit ENTER.
  • Wait for the unit to boot.
  • Type enable and hit ENTER. You won't need a password. You're now logged in with the old configuration.

2. Erase the old configuration:

  • Type erase startup-config and hit ENTER.
  • Answer Y to confirm.
  • Type  reloadto restart the unit.
  • Answer N to saving the configuration.
  • The unit will reboot with no configuration.

3. Load the factory default configuration:

  • Download the default configuration from https://supportforums.adtran.com/docs/DOC-5917
  • Unzip the file and save the resulting text file to your clipboard.
  • When the unit boots, type enable and hit ENTER.
  • Type config t at the prompt.
  • Paste the default text file into the terminal window.
  • Type Ctrl-Z to exit the configuration mode.
  • Type wr mem to save it to memory.

That's it. You can reboot now, or just start entering your own configuration.

I guess some firmware works differently.  

Is there another way to delete the config on the TA908e?
