ABSTRACT:
A system for dissipating electrostatic build-up from a circuit card to a chassis ground within an electronic system, prior to connection of the circuit card with the electronic system. A circuit card has a card connector for connecting the circuit card into a backplane receptor within the electronic system. The circuit card includes a surface upon which an electrostatic charge may collect and also includes at least one conductive pad. A card guide aligns the circuit card such that the circuit card connects with the backplane receptor when said circuit card is fully inserted into the card guide. A conductive element within the card guide couples the conductive pad to a chassis ground within the electronic system when the circuit card is partially inserted into said the card guide.
