EMI shielding for components
 This disclosure pertains to an apparatus and method of providing EMI shielding for an electrical component. The apparatus includes an elastomeric gasket, which is coated with a conductive jacket, and which is mounted on the backplane of a cabinet, the backplane providing EMI shielding. The cabinet is adapted for the insertion of a plurality of electrical components, such as disk drives, tape drives, and power supplies, which themselves are mounted in a rigid frame member. The frame member includes EMI shielding for the components on five of their six sides. The sixth side is unshielded, due to the fact that it contains the electrical connector used to connect the component to the backplane of the cabinet, when the frame member is inserted in the cabinet. With the frame member providing shielding on five sides, and the backplane providing shielding for the sixth side, the gasket serves the purpose of establishing an electrical seal between the frame member and the backplane of the cabinet.
