ABSTRACT:
A method and apparatus for supplying cooling air to electronic equipment from ones of at least two sources. A detector detects whether the quality, such as the temperature of the cooling air from a source, is satisfactory and if not shuts the damper to that source and opens the damper to another source. A main controller provides additional control signals for controlling the dampers to protect the electronic equipment, or for shutting down the electronic equipment.
