Abstract
A self-actuating damper for each slot of a multi-slot printed circuit board assembly cage allows proper air-cooling without regard to the presence or non-presence of card board assemblies in the slots. The damper of each slot is automatically held in the closed position when the respective slot is empty. An actuation hook implemented on each of the card board assemblies engages the actuator of the damper as card board assembly is aligned with the slot and automatically actuates the damper to an open position as the cell board assembly is inserted into the slot.
