Abstract
A server blade system includes a plurality of slots for receiving server blades. The system includes an air moving device to move air through each of the server blades installed in the system. When one of the server blades is removed, a bypass damper rotates into the empty slot to obstruct the flow of air through the slot. The bypass damper is pivotally mounted within each slot and includes a torsion spring to move the damper into the obstruction position. Two hinge pin mounts, which are “U” shaped in cross section, provide a snap fit for two hinge pins positioned at one end of the bypass damper. A spring mounting pin is positioned between the two hinge pins and a torsion spring is mounted over the spring mounting pin.
