RAGERIX,
Per the Total Access 900 Series (3rd Generation) document (61213908F1-13A) the unit comes with a default IP address of 10.10.10.1.
You can factory default the unit using "erase startup-config". Per the document "The device will have a blank configuration upon reboot." Also "Upon reboot, you will have to reconfigure the unit using the port labeled CRAFT." which lead you to believe that the default IP address of 10.10.10.1 is deleted and you have to use the serial CRAFT port to access the CLI and reprogram the management IP.
Hope this helps.
Regards,
