Patent ID: 8243469

Claim:
An input/output cable port assembly for an electronics rack comprising: a cable port structure defined in the electronics rack with an opening for input/output cables to pass therethrough; a first partition configured to couple to the cable port structure and reside within the opening of the cable port structure, the first partition comprising at least one first ferrite inductor portion; a second partition configured to couple to the cable port structure and reside within the opening of the cable port, structure, the second partition comprising at least one second ferrite inductor portion; wherein the first partition and the second partition are configured to be disposed adjacent to each other as adjoining partitions within the opening in the cable port structure, and when disposed as adjoining partitions within the cable port structure, the at least one first ferrite inductor portion and the at least one second ferrite inductor portion mate and define a ferrite inductor with a central opening for at least one input/output cable of the electronics rack to pass therethrough, wherein the ferrite inductor attenuates electromagnetic interference resulting from transient or steady state current on the at least one input/output cable passing therethrough; and wherein at least one of the first partition or second partition comprises a compressible elastomer layer, and wherein with the first partition and the second partition disposed as adjoining partitions within the cable port structure, the at least one first ferrite inductor portion, the at least one second ferrite inductor portion and the compressible elastomer layer are sized and disposed so that the compressible elastomer layer applies force to at least one of the at least one first ferrite inductor portion or the at least one second ferrite inductor portion to ensure that the at least one first ferrite inductor portion and the at least one second ferrite inductor portion physically contact without an air gap therebetween and define the ferrite inductor with the central opening through which the at least one input/output cable passes.
