in the middle of setting up power went out and i cant get back in to the adtran at all
The only way to do that is to use the console cable and bypass the password requirement. Here's a link to the Adtran video and document to do that:
[video] - Password Recovery in AOS
i can get on boot strap but how can i reset back to factory settings so i can start over.
You can either erase the startup-config or download the factory configuration and copy that to overwrite the current configuration.
You can look at this guide: Restoring an AOS Device to Factory Default
Hope this helps,
