Bypass password on the Adtran Total Access 900 Series VoIP Gateway

Posted: January 21, 2012 in Adtran, VoIP Gateway

Bypassing the passwords on the AOS requires a straight through serial cable to the console port of the unit.
Configure a VT100 session (i.e. PuTTy) using the following settings: 9600 bps, 8 bits, no parity, 1 stop bit and no flow control.
Now apply power to the unit.
As the unit boots you will be given the opportunity to break into bootstrap mode by pressing the ESC key within 5 seconds.
Next type the following:
Bootstrap# bypass passwords
Bootstrap# boot

The system will now boot with the password removed.
