Abstract
A system and method are provided for monitoring the connection of electronic equipment, such as remote computer workstations, to a network via a communication link and detecting the disconnection of such equipment from the network. The system includes current loops internally coupled to protected pieces of equipment so that each piece of associated equipment has an associated current loop. A low current power signal is provided to each of the current loops. A sensor monitors the current flow through each current loop to detect removal of the equipment from the network. Removal of a piece of hardware breaks the current flow through the associated current loop which in turn may activate an alarm. This invention is particularly adapted to be used with an existing 10BaseT communication link or equivalent thereof, employing existing wiring to form the current loops.
