Abstract
A multi-device chassis air filter characterization system includes a multi-device chassis, an air filter that is included on the multi-device chassis, and a plurality of computing devices that are housed in the multi-device chassis. Each of the computing devices determines that a current time corresponds to a predetermined air filter characterization time period and, in response, operates a cooling system in that computing device at a predetermined cooling system operating level for the predetermined air filter characterization time period. A first computing device that is included in the plurality of computing devices measures an air filtering characteristic provided by the air filter during the predetermined air filter characterization time period and, based on the air filtering characteristic, determines whether to generate an air filter replacement alert.
