Abstract

Commonly, a data processor is supported by a raised floor that provides a space below the processor for cables that connect the processor to a source of electrical power and carry signals between the processor and other components. The cables enter the processor through corresponding holes in the raised floor and the bottom of the processor enclosure. The processor enclosure and the raised floor are electrically conductive and thereby provide electromagnetic shielding for the cables. It has also been proposed to shield the cables in the space between the bottom of the processor enclosure and the raised floor. Shielding for the cables is advantageously implemented by a bellows structure. In cross section the bellows is circular or non- circular to correspond to the shape of the holes in the enclosure and the raised floor.
