An electronic equipment module includes a symmetrical casting with two chassis
units. Each unit includes a mounting recess to receive a circuit assembly, separated
by a cover applied to either unit, or both. The module is normally mounted to a
unit rack, and typically has a removably attachable, re-orientable keyed surface
which mates with another keyed surface on the rack. A mounting system includes
a unit rack coupled to at least one electronic equipment module and a mounting
frame. A method of mounting an electronic equipment module includes inserting the
module into an open end of a unit rack, electrically coupling connectors attached
to the module and the rack, securing the module to the rack, and attaching the
rack to a mounting frame. The module can be secured to the rack by engaging a cam
lever attached to the module.
