A sealed electronic equipment enclosure with a dedicated cooling system is fitted with movable louvers in the enclosure walls. During normal operation, air pressure developed by the dedicated cooling system keeps the louvers closed and maintains the enclosure sealed to the computer room environment. If the dedicated cooling system fails, the internal air pressure developed by the cooling system is reduced and air movers in the electronic equipment force the louvers open, thereby allowing the air movers to draw cooled air from the computer room into the enclosure. This cooled air prevents the equipment from overheating at least for a time period long enough to allow the dedicated cooling system to be replaced or repaired.
