Abstract
A system for connecting printed circuit boards to card cages. In addition to a conventional pin-and-socket connector arrangement for making signal and main power connections, the printed circuit board has a conducting pad coupled to the power traces of the board. A clip mounted in the card cage and connected to a first power source isolated from the main power source engages the pad before the conventional connectors make contact. Thus, the board is powered up first. As the board is fully seated and the conventional power and signal connections made, the power clip slides off the pad to break contact, leaving the main power source supplying power to the board.
