Abstract
An input/output cable port assembly and electromagnetic interference attenuation method are provided. The cable port assembly includes a cable port structure mounted to an electronics rack with an opening for input/output cables to pass therethrough, and multiple bottom ferrite inductor portions and multiple top ferrite inductor portions. The bottom and top ferrite inductor portions include first and second surfaces, respectively. The inductor portions are configured to be stacked within the cable port structure with their first and second surfaces in opposing relation to define at least one ferrite inductor with a central opening defined by the first and second surfaces for input/output cable(s) of the electronics rack to pass. The ferrite inductor attenuates electromagnetic interference resulting from transient or steady state current on the cable(s) passing therethrough.
