Abstract
A device that enables a card to be hot-plugged into a socket on a processor-base machine includes a signal bus arbitrator, a signal bus switch, a power bus switch, a cover plate switch, status signals and a controller. The controller monitors the status signals and other signals from the cover plate switch and the signal bus arbitrator to generate control signals that activate the power bus switch and the signal bus switch to control power and signal transmitting facilities at the socket.
