Housing equipment with side-to-side airflow creates many challenges for IT and facility managers, particularly in regards to cooling. Because most enclosures are designed for a front to back airflow pattern, it is difficult to maintain ideal operating temperatures on side-to-side airflow equipment. The Rack Side Air Distribution Unit allows for greater security and organization by allowing racks to be placed adjacent to one another without impeding airflow. The Rack Side Air Distribution Unit is a 2U rack mountable air distribution product for networking equipment or servers with side-to-side airflow. It pulls in conditioned air from the front of the rack and distributes it to the side air intake of the networking equipment. This extends equipment life by providing proper inlet temperatures. This product is recommended for one or more networking products that are stacked consecutively in a rack. Rack Side Air Distribution Units may be placed above and/or below the networking equipment. Airflow pattern is user configurable via an interchangeable air turning vane.
