Abstract
A computer system having two ports for connecting the computer system to a computer network by means of different transmission media types. Electronic switching is implemented to select between these two ports. The electronic switching is controlled by software. Depending upon which of the two ports is being utilized to connect the computer system to the network, power is either switched on or off to a transceiver. The switching can be accomplished by a voltage regulator with an enable signal or by means of a MOSFET. The computer system can detect which of the two ports is being utilized as a connection to the network by sending a data packet through each of the ports and determining the status of the transmissions.
