Abstract

An electronic equipment cabinet having a duct positioned in a side portion of the cabinet. The duct has a first opening formed in a bottom wall of the duct and a second opening formed in an inside wall of the duct. The first opening is configured to generally align with a cool air source and receive cool air from the cool air source with the first duct installed in the cabinet. The second opening is in fluid communication with a front internal portion of the cabinet and is configured to direct cool air from the duct to the front internal portion of the cabinet with the duct installed in the cabinet.
