Abstract

According to one embodiment of the invention, an integrated jack unit is provided. The integrated jack unit includes a housing. The integrated jack unit also includes a jack positioned at least in part in the housing. The integrated jack unit also includes a power controller positioned in the housing and coupled to the jack by a line. The line is designated for coupling with a transformer. The integrated jack unit also includes a pin protruding outwardly from the housing. The pin is electrically coupled to the jack through the power controller and the line. The pin is positioned to receive power for the jack from a printed circuit board.
