Abstract

A modular serviceability sled includes a frame, subassembly, interconnection, gasket, and shielding component. The interconnection is operatively connected to the subassembly and includes an electrical, pneumatic, and/or hydraulic connection. The gasket can engage the frame and a base assembly of an apparatus. The shielding component can contact the frame and the base assembly and includes an electromagnetic interference and/or radio frequency shielding component. The sled is movable between an engaged state and a disengaged state. In the engaged state, the sled is at least partially within a receiving space of the apparatus, the gasket engages the frame and the base assembly, the shielding component contacts the frame and the base assembly, and the interconnection is operatively connected to a machine interconnection of the apparatus. In the disengaged state, the interconnection is disconnected from the machine interconnection and the sled is configured to freely move with respect to the base assembly.
