A Universal/Portable Cable Support and EMI Reduction Bar which to attenuate electromagnetic interference on the input/output cables of the electronics rack passing therethrough before the cables exit the rack. The bar works for cables exiting any part of the rack. The design involves an introduction of a grounding bar that can serve as EMI suppression (detuning frame resonance and reducing cable emissions) as well as cable support/retention functions. The bar provides a stable Ethernet cable support and EMI (Electromagnetic Interference) suppression structure which reduces EMI emission on the cable as well as eliminates the extra connection needed when using a separate RF (Radio Frequency) choke. A device, system and method are provided.

Aspects of the present invention provide shielded cables for reducing the incidence of ground loops between connected electronic devices. According to one aspect of the present invention, a shielded cable is disclosed having two inner shield segments and an outer shield. The inner shield segments can each be grounded, but are physically separated from each other by a gap. The external shield is not grounded, and serves to contain EMI generated by signal conductors within the shielded cable and shield the signal conductors against external electrical events.

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.

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.
