Abstract
Disclosed is a system and method employing a magnetic proximity switch to enable the transfer of power between a power supply unit and a docking unit or to transfer data between a docking unit and a peripheral module such as a disk drive or controller module. Power may be transferred through the switch, or a signal from the switch may be employed to enable a control circuit. The control circuit may control a plurality of voltages or currents and may ramp voltages or currents to limit surge current when a module is installed or removed. The control unit may also be employed to place data and control signals in a high impedance state when a module is not docked, limiting electromagnetic radiation.
