Abstract
An input/output cable port assembly and electromagnetic interference (EMI) attenuation method are provided. The port assembly includes a cable port structure for an electronics rack with an opening for input/output cables to pass therethrough, and a first and a second partition. The first and second partitions couple to the cable port structure and reside within the opening. The first partition includes at least one ferrite inductor portion and the second partition includes at least one second ferrite inductor portion. The partitions are configured to be disposed adjacent to each other as adjoining partitions within the cable port structure, and when disposed as adjoining partitions, the first and second ferrite inductor portions mate and define a ferrite inductor with a central opening for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state currents on the cable(s) passing therethrough.
