Abstract
An apparatus comprising a chassis providing a plurality of module bays, one or more modules received in the module bays, wherein each module has at least one damper actuator extending from a distal end of the module. A fan assembly and a plurality of air flow dampers are secured in a distal end of the chassis, wherein each damper is aligned with one module bay to control air flow through the aligned module bay. Each damper is biased to close in the absence of contact with a damper actuator and opens in response to contact with a damper actuator. Each damper opens to a variable extent determined by the profile of the contacting damper actuator. The damper actuator of a particular module has a profile corresponding to the thermal load of that module, such that installing a module into the chassis automatically opens the aligned damper to the desired extent.
