If you define multiple Metasys servers (ADS/ADX devices) and you delete the ADS/ADX that is defined as the Site Director, the top Metasys server shown in the all items navigation tree of the SCT archive database automatically becomes the Site Director.
Note: The ADS-Lite cannot be the Site Director for
any other ADS or ADX server.
If necessary, change the Site Director in the site object. See Configuring an ADS/ADX as Site Director.
