An apparatus is provided in one example embodiment and includes a plate having a plurality of perforations configured in a pattern. The pattern includes the plurality of perforations arranged in concentric circles centered at a point. Each of the perforations is a closed shape comprising four edges, with rounded corners between adjacent edges, with two opposite edges of each of the perforations including non-parallel straight lines and two other opposite edges comprise concentric, offset curved lines. The non-parallel straight lines may form an angle with a vertex at the point, and the concentric curved lines may be centered at the point. The perforations in each concentric circle may be angularly spaced around the point. The apparatus may further include a substantially circular fan.

A high insertion force ejector is provided. The high insertion force ejector includes an ejector mounting base, a pressure bar-ejector tooth, a first cam, and a second cam. The pressure bar-ejector tooth is connected to the ejector mounting base. A lever handle is operatively connected to the pressure bar-ejector and the ejector mounting base. The first cam and the second cam are operatively connected to the pressure bar-ejector tooth and the lever handle.

An enclosure has a perforated front door with a replaceable filter, and a perforated rear side allowing air to flow through the enclosure. The enclosure also has mounting brackets for heat generating elements, such as line cards or other rack mounted electronics. A fan draws air through the perforated front door, though the filter, and across the heat generating elements. Side brushes are disposed on a side wall near the front of the enclosure, which allow any cables attached to the heat generating elements to exit the enclosure. The front door is removable, opening up one side of the side brushes and allowing the cables to slide in the side brushes while still connected to the heat generating elements.

A dual-cam ejector assembly for a card, such as a line card, is provided. The ejector assembly comprises an elongated ejector arm having its distal end coupled to the line card so as to provide a first axis of rotation for the ejector arm. The ejector assembly further comprises an ejector cam coupled to the line card so as to provide a second axis of rotation for the ejector cam. The ejector assembly also comprises a cam pin extending from the ejector cam that couples the ejector cam to the ejector arm such that pivoting of the ejector arm around the first axis of rotation causes the ejector cam to pivot around the second axis of rotation.
