Rack-mountable assembly with electromagnetic shielding structure(s)

Rack-mountable assemblies are provided which include a cover configured to fixedly mount to a frame of an electronics rack, and a drawer configured to slidably mount to the frame adjacent to the cover to slide relative to the cover. When operatively mounted to the frame, the cover and drawer together define an enclosure for one or more electronic components. The assembly further includes an electromagnetic shielding structure to provide, at least in part, electromagnetic shielding at a gap between the cover and drawer when operatively positioned within the electronics rack. The electromagnetic shielding structure includes an electromagnetic shielding plate which overlies, at least in part, the gap between the cover and the drawer, and which self-adjusts with sliding of the drawer into the electronics rack to facilitate providing the electromagnetic shielding at the gap between the cover and the drawer.
