Abstract: The present invention is directed to a network chassis having a system backplane board, a subassembly backplane board, and at least one connector disposed on each of the system backplane board and subassembly backplane board for electrically connecting the system backplane board to the subassembly backplane board. The chassis includes a mounting mechanism for rotatably coupling the system backplane board to the chassis and defining a path of rotation therefor, and an ejection mechanism mounted to the system backplane board to unseat the connector of the system backplane board from the connector of the subassembly backplane board. The ejection mechanism selectively exerts a force against the chassis that is directed linearly outwardly from and perpendicularly to the system backplane board. The ejection mechanism further comprises a fastener for releasably engaging the system backplane board to the chassis.

Abstract: A chassis for use in housing heavy electrical equipment is provided with lifting devices for attachment of the chassis to a telescoping rail assembly, such as may be found on a conventional EIA equipment rack. The chassis includes a housing with a sidewall having a recessed wall to which handles and support brackets are permanently attached. The handles are hingedly connected to the recessed wall and may be pivoted over an arc between an extended position that is suitable for lifting operations and a retracted position adjacent the recessed wall. The support brackets may be selectively rotated between an assembly position that supports the chassis atop the telescoping rail assembly and a position of normal use that does not interfere with depthwise extensile and de-extensile motion of the telescoping rail assembly and chassis.

Abstract: A cable retention device comprises a conduit that is joined to an end plate forming a continuous passage through the conduit. Cable shielding is clamped to the conduit to establish a pathway to ground. The end plate presents a shoulder face that is inserted into a guide rail clamp. The shoulder face includes a pair of arches that function as fulcrums to flex the guide rail bracket, which secures the cable retention device to a chassis under compressive force.

Abstract: A channel cover is used to protect nonfunctional buttons until such time as the nonfunctional buttons are made functional in consequence of a system upgrade. The channel cover includes a bight, a first leg and a second leg. The first leg has a lip for mating engagement with female structure on at least one of the buttons.

Abstract: A drive unit quick release apparatus is provided on one guide rail of a pair of guide rails mounted to the drive unit for engaging and releasing a drive unit from a chassis. The apparatus includes a resilient cantilevered arm mounted to the drive unit, an engaging structure positioned on the arm to selectively maintain the drive unit in the chassis, and a lever connected to the resilient arm to facilitate disengaging the engagement structure and removing the drive unit from the chassis. The lever is positioned generally perpendicular to the resilient arm and to the axis of travel of the drive unit out of a bay in the chassis. In this configuration, a force applied to the lever causes the resilient arm to flex inwardly and disengage the engaging structure from a retaining slot in the chassis. Additionally, the continued application of the force to the lever moves the attached drive unit out of the chassis.
