Abstract
A fan speed control system (200) for an electronic equipment enclosure comprises means for determining temperature (201, 202, 203, 210, 211) at a plurality of locations within the enclosure, means for determining operating parameters (201, 202, 203, 212) for the fan control system, means for setting operating speed (201) of at least one cooling fan, and means for exchanging information signals (205, 217, 218) relating to fan speed control system operation with an external controller. A method is also provided for controlling fan speed for an electronic equipment enclosure comprising the steps of determining temperature at a plurality of locations within the enclosure, determining operating parameters for the fan control system, setting operating speed of at least one cooling fan, and exchanging information signals relating to fan speed control system operation with an external controller.
