Zero height power unit shelf system

An electronics equipment chassis, comprising:

• a frame;
• and
• an electronics module receptacle coupleable to said frame, said receptacle including:
• a torsion bar;
• a first planar sidewall having a boss located on an inside planar surface thereof, said boss configured to cooperatively engage a notch formed on a side wall of said electronics module and further having a semicircular locking slot formed in a front edge of said first planar sidewall configured to receive a locking cam associated with said electronics module, said semicircular locking slot cooperating with said locking cam and said boss to create a longitudinal compressive force along said first planar sidewall, said first planar sidewall coupled to said torsion bar;
• and
• a second planar sidewall coupled to said torsion bar and opposing said first planar sidewall.

A method of manufacturing a receptacle configured to receive an electronics module for use with an electronics equipment chassis, comprising:

• forming a torsion bar;
• forming a first planar sidewall having a boss located on an inside planar surface thereof, said boss configured to cooperatively engage a notch formed on a side wall of said electronics module and further having a semicircular locking slot formed in a front edge of said first planar sidewall configured to receive a locking cam associated with said electronics module, said semicircular locking slot cooperating with said locking cam and said boss to create a longitudinal compressive force along said first planar sidewall, said first planar sidewall coupled to said torsion bar;
• and
• forming a second planar sidewall coupled to said torsion bar and opposing said first planar sidewall.
