Abstract: Embodiments disclosed herein relate to an optical disc drive test. In one embodiment, an optical disc drive of a host electronic device performs a test on itself. The host electronic device requests information about the test from the optical disc drive. The optical disc drive reports information about the test in response to the request.

Abstract: A drawer, of the type constructed to carry electronic apparatus, and to be inserted into a cabinet, includes at least two separate connector parts adapted to mate with corresponding connector parts mounted on a backwall or backplane of the cabinet. An alignment mechanism, comprising a pair of alignment pins extending from the cabinet backplane, and multiple pairs of apertures associated with the drawer, each pair corresponding to one connector, function to align the separate connector parts on the drawer to those mounted on the backplane of the cabinet.

Abstract: An electronic assembly includes an electronic module mountable to a backplane having a ground plane for grounding and EMI shielding. The electronic module includes a conductive chassis having a floating chassis board. Interface connectors are mounted to the chassis board and to the backplane and mate with one another when the electronic module engages the backplane. A grounding clip is mounted to the chassis board and is used to engage an alignment pin extending from the backplane. The grounding clip includes a laterally extending resilient arm which grounds the clip to the chassis. The alignment pin is electrically connected to the backplane ground plane and the grounding clip is electrically connected to the chassis board ground plane so that both ground planes are grounded to the chassis through the grounding clip. The backplane includes a ground pad which circumscribes the interface connectors and is connected to the ground plane.

Abstract: The invention is directed to a combined guide and barrier for the edge mounting of ciruit boards within a housing. The barrier guides are designed to be used in multiples in high density packing applications. The barrier guide includes a top, a bottom and a barrier extending between the top and bottom. The top and bottom have opposed grooves facing one another. The grooves guide and position the printed circuit within the housing. The barrier, positioned near and parallel to the grooves and extending along the length of the top and bottom, helps prevent the user from inadvertently coming into contact with exposed edge connectors or adjacent circuit boards after a circuit board is removed from the housing. The barrier also guides cooling air through the housing.
