An elevator provides for lifting and disconnecting an electronic device from a chassis circuit board and the subsequent removal of the device from a chassis slot. A sliding element between the device and the slot includes tracks within which travel followers associated with the electronic device. Motion in a first direction the tracks causes the tracks to move with respect to the followers, raising the device away from the circuit board. In a fully raised position, the device is disconnected and may be removed from the slot. Motion in the opposite direction causes the relative motion between the track and follower to lower the device toward the circuit board. In a fully seated position, the device is connected to the circuit board.
