IBM Enterprise Rack (42U) Installation Options
The IBM Enterprise Rack is the premier IBM rack, offering four deep side bays that enable the greatest variety of side bay
mounting options. This flexibility is one of the major benefits of choosing this rack. Using all the available space in the side bays of
this rack enables customers to install up to 84 outlets in this rack without sacrificing any valuable “U” space. The picture below
details these side bays and provides a lettering and numbering guide to make explaining installation location easier. It is
important to note that the Enterprise Rack bays do not accommodate two Enterprise or Ultra Density Enterprise PDUs in one bay
due to lack of a clean way to route power cords from mounting location C and D.
