Abstract
An improved cooling system for electronic components wherein an air supply housing with two openings cooperates with a manifold with one opening to allow air distribution from the air supply housing through the manifold to a card cage both while the manifold is closed for normal operation and while the manifold is extended to allow maintenance of the electronic components. When the manifold is closed for normal operation, the first opening in the air supply housing is blocked by the manifold and air flows into the manifold through the second opening. When the manifold is extended for maintenance, air flows into the manifold through the first opening and the second opening is blocked by a flapper which swings down over the second air supply housing opening.
