If authentication is enabled in the merging unit and the administrator password is lost, it is no longer possible to change passwords or operate the merging unit with full access rights.

The administrator password can be restored to the default value using a one-time password. The OTP functionality is only available via the merging unit's front port.

Contact ABB technical customer support to retrieve the administrator level access to the merging unit.

  1. Using the front RJ-45 port, connect a PC to the merging unit.
  2. Open the Web browser and go to https://192.168.0.254/otp.html.
  3. Forward the displayed OTP related information to ABB technical customer support to receive a one-time password.
  4. Reset the administrator password.
    1. Type the ADMINISTRATOR username with capital letters.
    2. Type the one-time password.
    3. Click Reset.
  • If the password is successfully reset, restart the browser and log in as administrator using the default password.
  • If the password reset fails, try again or contact ABB technical customer support again.
