Abstract
A sensing apparatus for detecting a disconnection in a connector for interfacing a component module in a computer system. A first portion of the connector is coupled to the computer system and a second portion of the connector is coupled to a component module in the computer system. The connector portions include electrically conductive portions that mate to enable communication and/or transmission of power signals between the component module and the computer system. One or more sense signals are applied to a predetermined number of electrically conductive portions on the first portion of the connector. A set of corresponding electrically conductive portions on the second portion of the connector are connected to ground. When the connector portions properly mated, the sense signals applied to the first portion of the connector are pulled to ground. A logic circuit provides an output signal indicative of whether the sense signals are pulled to ground on the corresponding set of electrically conductive portions on the first portion of the connector. If the sense signals are pulled to ground, then the logic circuit allows power to be supplied to the component module. When the sense s…
