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.

1. In an array of independent discs, an electrical connection system comprising:a cabinet including at least one docking unit;a module that may be docked to said docking unit;a first surface of said docking unit that does not have a magnet attached thereto;a first magnet affixed to a second surface of said module;a first switch positioned on said first surface of said docking unit;a first circuit that receives a first switch signal from said first switch and transfers a voltage from said docking unit to said module through a connector when said first switch signal is active and that inhibits transfer of said voltage from said docking unit to said module when said first switch signal is not active;a first surface of said module that does not have a magnet attached thereto;a second magnet affixed to a second surface of said docking unit;a second switch positioned on said first surface of said module; anda second circuit that receives a second switch signal from said second switch and that enables said module to drive data signals to said docking unit when said second switch signal is active.2. The system of claim 1 further comprising:an indicator signal derived from said first switch signal that indicates the presence of said module.3. The system of claim 1 wherein said first circuit ramps said voltage supplied to said module.4. The system of claim 1 wherein said module supplies a second voltage to said docking unit.5. The system of claim 1 wherein said module is a storage controller module.6. The system of claim 1 wherein said module is a disk drive module.7. The system of claim 1 wherein said first circuit enables said docking unit to drive data signals to said module.
