Systems and methods for retention of riser assemblies

An information handling resource assembly comprising:

• a first housing for carrying a first information handling resource having a first edge connector configured to mechanically and electrically couple to a first receptacle connector formed on a circuit board;
• and
• a rotating latch rotatably coupled to the housing via an axis substantially perpendicular to a surface of the circuit board when the first edge connector is coupled to the receptacle connector, the rotating latch comprising:
• a body;
• a first engagement feature extending from the body in a direction substantially parallel to the surface of the circuit board when the first edge connector is coupled to the receptacle connector;
• and
• a second engagement feature;
• wherein the rotating latch is movable between:
• a closed position in which the first engagement feature is configured to engage with a corresponding first mechanical feature of a second information handling resource assembly having a second edge connector configured to mechanically and electrically couple to a second receptacle connector formed on the circuit board in order to mechanically maintain the second information handling resource assembly in a fixed position relative to the information handling resource assembly and further in which the second engagement feature is configured to engage with a second mechanical feature of the chassis in order to mechanically maintain the first information handling resource assembly in a fixed position relative to the chassis;
• and
• an open position in which the first engagement feature is disengaged from the first mechanical feature and the second engagement feature is disengaged from the second mechanical feature.

A method for constructing an information handling resource assembly comprising:

• rotatably coupling, via an axis, a rotating latch to a first housing for carrying a first information handling resource having a first edge connector configured to mechanically and electrically couple to a first receptacle connector formed on the circuit board, wherein the axis is substantially perpendicular to a surface of a circuit board when the first edge connector is coupled to the receptacle connector, wherein the rotating latch comprises:
• a body;
• a first engagement feature extending from the body in a direction substantially parallel to the surface of the circuit board when the first edge connector is coupled to the receptacle connector;
• and
• a second engagement feature;
• wherein the rotating latch is movable between:
