A shutter mechanism for rack mounted chassis systems, comprising a first apertured shutter and a second apertured shutter, the first apertured shutter having a plurality of first holes formed therein in a first pattern, the second apertured shutter having a plurality of second holes formed therein in a second pattern, the first holes and the first pattern being configured relative to the second holes and the second pattern such that the shutters are positionable in a non-aligned position blocking air flow therethrough and in an aligned position allowing air flow therethrough, the shutters being movable to the non-aligned position when exposed to a temperature above a predetermined amount and means for positioning the first apertured shutter adjacent to the second apertured shutter allowing relative slidable movement thereof.

1. A rack mounted chassis system, comprising in combination:a chassis having a top opening; a top shutter mechanism positioned over said top opening of said chassis, said shutter mechanisms having a generally planar configuration corresponding to said top opening of said chassis and including a first apertured shutter slidably connected to a second apertured shutter, said first apertured shutter having a plurality of first holes formed therein in a first pattern substantially throughout said generally planar configuration, said second apertured shutter having a plurality of second holes formed therein in a second pattern substantially throughout said generally planar configuration, said first holes and said first pattern being configured relative to said second holes and said second pattern such that said shutters are positionable in a non-aligned position blocking air flow therethrough and in an aligned position allowing air flow therethrough, said shutters being movable to the non-aligned position when exposed to a temperature above a predetermined amount.
