Electronic equipment module mounting apparatus and method

A module retention device, comprising:

• a cam lever extending along a first axis attached to a pivot extending along a second axis;
• an engagement lug attached to the cam lever;
• and
• a rotating fastener attached to the cam lever and capable of rotation about a third axis, wherein the first, second, and third axes are non-parallel, wherein the pivot and the engagement lug are not located coaxially, and wherein the pivot and the engagement lug are offset by a selected distance.

An electronic equipment module, comprising:

• a chassis unit having an exterior surface including a pivot and a rear face including a first electric connector mounted thereon, the exterior surface of the chassis unit capable of slidable engagement with an interior surface of a unit rack including a second electric connector mounted to the interior surface;
• a cam lever attached to the pivot, wherein the cam lever includes an engagement lug capable of slidable engagement with a slot located on the interior surface of the unit rack, wherein the first connector is capable of electrically coupling to the second connector when the cam lever is in an engaged position, and wherein the first connector is not electrically coupled with the second connector when the cam lever is in a non-engaged position;
• and
• a rotating fastener attached to the cam lever and capable of rotatable engagement with the chassis unit so as to secure the cam lever in the engaged position, wherein the rotating fastener is a quarter-turn locking fastener.
