Upgrade the rack's cooling capacity Back-to-Back racking requires that the cooling capacity of the rack be upgraded. The cooling upgrade requires installation of a new Exhaust Fan Assembly (product E7687A). This assembly contains three fans, an LED fault indication circuit and a 1- EIA unit air scoop. This is required to promote maximum airflow through the center of the rack. Also, to promote additional air flow, the rear cabinet door will be removed and set aside. To maintain cooling efficiency, filler panels should be installed in any unfilled spaces in the front and back of the rack (see Table 19). Racking 239
