Abstract: In accordance with the teachings of the present invention, a system and method for providing a circuitry management service is provided. In a particular embodiment, the system includes a management circuit interface configured to receive a plug associated with a management service. The system also includes a power source. In addition, the system includes a management circuit operable to facilitate the management service. The management circuit includes one or more management circuit devices coupled to ground. The management circuit is coupled to the management circuit interface such that one or more of the management circuit devices are coupled to the power source only when the management circuit interface receives the plug.

Abstract: Apparatus for redundancy circuit protection includes a controller (20), a plurality of circuits (22) coupled to the controller (20), and a redundancy switch (50) coupled between the plurality of circuits (22) and a network. The redundancy switch (50) is adapted for connecting or disconnecting selected ones of the plurality of circuits (22) to or from the network. In addition, a predetermined number of spare circuits (52) with similar functionality as the plurality of circuits (22) are coupled to the high density bank control unit (20), so that the redundancy switch (50) may connect or disconnect selected ones of the predetermined number of spare circuits (52) to the network and establish a transmission path from the controller (20) through the selected spare circuits (52) to the network.
