ABSTRACT:
A method and system for controlling electronic component configuration. The system includes a guard including an aperture and a plate including an aperture are adjustably connected. The guard and the plate each include a pin connected thereto. The system is capable of adjusting configurations to obtain an open configuration where at least a portion of the guard and plate apertures align and a blocked configuration where the plate and the guard apertures fail to permit access. Depending on an introduced component characteristic the component's physical keying structure may be received or prevented depending on the implementation. Additionally the present invention permits retrofitting a component with a correct characteristic but lacking a keying structure by disposing plate/guard pins outside the footprint of an introduced electronic component.
