Abstract: Within an electronic shelf, physically separating or isolating in a front to rear direction keying elements from connector alignment elements to provide a separation distance, minimizes the undesirable interaction that may occur between keying elements and connector alignment elements due to tolerance effects. Worst case manufacturing tolerances with respect to keying elements, for example, no longer influence in any significant way, the co-action of the connector alignment elements. Insertion of circuit packs into respective receiving stations is achieved with less effort since effort is not required to overcome extra frictional forces resulting from the keying elements interacting with the connector alignment elements.
