Patent ID: 7492608

Claim:
A data storage system including an EMI shield, comprising: a chassis, the chassis including at least one bay for receiving a replaceable unit and a lip, the replaceable unit including a housing and a faceplate; and a gasket formed of conductive foam material operationally coupled to the replaceable unit housing and the replaceable unit faceplate for reducing electromagnetic radiation emissions from the replaceable unit and chassis interface, the gasket including four sides which are continuous and configured to provide a varying force-compression curve along the length of the gasket by varying a thickness of the four sides of the gasket; wherein upon installation of the replaceable unit the lip defined within the chassis compresses the gasket to provide a constant force per unit length and form a continuous electromagnetic interference shield with uninterrupted electrical conductivity, the gasket is continuous, and the gasket is die cut to geometrically match the replaceable unit faceplate, replaceable unit housing and chassis lip.
