摘要：A system or method ensures proper insertion of a circuit board (“card”)assembly into a card support assembly. A card assembly includes a first keying featureother than on a faceplate connected to the card assembly. The keying feature may be a
notch, tab or slot, and the keying feature may be integral with the card assembly. Thecard support assembly includes a second keying feature that corresponds to the firstkeying feature. The second keying feature is positioned so as to allow cards with thecorrect keying feature to connect with the support assembly and to prevent cards thatlack the keying feature, or are misaligned, from contacting the connectors of the supportassembly. As a result, an effective keying solution is provided for the card assembly, anddamage to circuit boards and connectors caused by improper connections is preventedwithout costly manufacturing processes.
