Abstract:
1. An input/output cable port assembly for an electronics rack comprising: a cable port structure mounted to the electronics rack, the cable port structure having an opening for input/output cables of the electronics rack to pass therethrough; multiple bottom ferrite inductor portions disposed within the opening of the cable port structure, each comprising a first surface; multiple ferrite inductor portions disposed within the opening of the cable port structure, each comprising a second surface; and wherein stacked pairs of bottom and top ferrite inductor portions with first and second surfaces in opposing relation define respective ferrite inductors, each ferrite inductor comprising a central opening defined by the opposing first and second surfaces, the central opening being sized for at least one input/output cable of the electronics rack to pass therethrough, wherein at least two ferrite inductors of the multiple ferrite inductors are constructed to attenuate electromagnetic interference of different ranges of frequency.
