Abstract

A novel system and method for simplifying the management of electronic equipment such as computers, networks, and equipment and communications systems. The system tracks equipment that has been registered in an inventory database without any user involvement. Once registered and connected into the system'"'"'s power source device, the equipment'"'"'s location will be easily tracked without human intervention. This information may be used to locate systems in need of up grade, repair or relocation, and further can verify that the correct equipment was moved and that it was moved to the correct location.
