Abstract: A system for installation and removal of an expansion card is disclosed. An expansion card is mounted to a cassette having a front plate and a back plate. The cassette is sized to fit within a chassis. The chassis is provided with a connector that is configured to receive a connection portion of an expansion card. The front plate inserts into the chassis and remains substantially vertically fixed after insertion. The back plate is pivotable with respect to the chassis when inserted. Once inserted, the back plate is pivoted downward to engage the contact portion of the expansion card with the connector. The back plate may be removable from the front plate to fasten expansion cards thereto. Fasteners securing the expansion card to the back plate may be adjustable.

Abstract: A control panel assembly includes a modular control panel box that is mounted to a door. The door is used to cover an opening that affords access to an internal component bay that resides within an electrical system housing. A tongue and groove joint provides a mechanism for selective positioning of the modular control panel box on the door such that the modular control panel box may be moved to a position that does not interfere with opening motion of the door that, otherwise, would occur when the modular control panel box moves rearwardly of the opening to contact an adjacent chassis.
