Bypass Adtran Router password, reset password and reconfigure.

Problem:  Acquired a used Adtran 3450 router and needed to configure it for a location that needed a router.   Problem was that I didn’t know the password for the web user, enable and the console user.   I needed to find a way to reset this router or change the password.

Solution:  To get into the router and bypass the passwords, you need to console into the router using a DB9 serial cable and a VT100 emulator like Putty or HyperTerminal.  When connected, pres ESC within the first 5 seconds of the unit powering on to get into bootstrap mode.  Once in bootstrap mode, type bypass passwords and press enter.  Then type boot and the unit will reboot, bypassing the need for passwords.

Reset Password:

  1. At the # prompt type config terminal and press Enter.
  2. At the (config)# prompt, type enable password password Where password is your new password.
  3. At the (config)# prompt, type username youruser password yourpassword and click enter.  Of course yourmuser and Your password are the user and password that you choose.  This will create a new administrator user where you can login without going into bootstrap mode.
  4. Type exit and the write mem to save the config.

Set the IP address to Eth1:

  1. At the # prompt, type config terminal and press enter
  2. At the (config)# prompt, type interface eth 0/1
  3. Enter ip address 10.0.0.1 255.255.255.0 (Put your desired IP address instead of the 10.0.0.1 supplied above.)
  4. Type exit and the write mem to save the config.

Make sure HTTP access is turned on:

  1. At the # prompt, type config terminal and press enter
  2. at the (config)# prompt type ip http server and press enter
  3. Type exit and the write mem to save the config

After you turn on HTTPS access, you can do all the other configuration via the web browser which is much easier.
