Abstract
One or more keys () can be integrally formed of a card cage and positioned to extend into the card-receiving openings of the card slots that comprise the card cage. The cards can then have key-receiving openings () that accommodate such keys. By matching the keys to particular physical and electrical functionality and compatibility attributes of a given card slot, such key-receiving openings can be similarly shaped and sized to assure that such cards cannot be inadvertently (or purposely) placed in an inappropriate card slot. In varying embodiments, such keys can be formed of a cable trough, a front panel, and a card guide seating surface.
