Universal/portable cable support and EMI reduction bar

An electronics system comprising:

• an electronics rack, the electronics rack comprising:
• a rack frame;
• at least one electronics subsystem disposed within the electronics rack and supported by the rack frame;
• and
• a cable support and electromagnetic interference (EMI) reduction device attached to the electronics rack, the device comprising:
• a cable support bar having at least one opening for at least one cable of the electronics rack to pass therethrough, the cable support bar having a first end and a second end and formed by joining a top section half and a bottom section half, the rack having a first side wall and a second side wall;
• the top section half of the bar having at least one top channel and the bottom section half of the bar having at least one bottom channel, wherein ferrite inductor portions are dispersed within and around the at least one top channel and the at least one bottom channel;
• a first attachment mechanism to attach and ground the first end of the bar to the first side of the rack;
• and
• a second attachment mechanism to attach and ground the second end of the bar to the second side of the rack;
• wherein:
• the top and bottom section halves of the bar are so disposed so that when the top section is attached to the bottom section the top section and bottom section thereby form an attached structure;
• the channels align to create the opening through which the at least one cable may pass;
• the attached structure applies force to the ferrite inductor portions to ensure that the top ferrite inductor portion and the bottom ferrite inductor portion make physical contact thereby forming an electromagnetic inductor around a cable passing through the opening;
• and
• at least one attachment mechanism is spring loaded in order to apply pressure to a side wall.

A method of supporting and attenuating electromagnetic interference on at least one input/output cable exiting an electronics rack, the method comprising:

• providing a cable support and electromagnetic interference (EMI) reduction bar for the electronics rack, the bar having at least one opening for at least one cable of the electronics rack to pass therethrough;
• the cable support bar having a first end and a second end and formed by joining a top section half and a bottom section half, the rack having a first side wall and a second side wall;
• the top section half of the bar having at least one top channel and the bottom section half of the bar having at least one bottom channel;
• and
• providing ferrite inductor portions around the at least one top channel and the at least one bottom channel;
• wherein:
• the top and bottom section halves of the bar are so disposed so that when the top section is attached to the bottom section, the top section and bottom section thereby form an attached structure;
• the channels align to create the opening through which the at least one cable may pass;
• the attached structure applies force to the ferrite inductor portions to ensure that the top ferrite inductor portion and the bottom ferrite inductor portion make physical contact thereby forming an electromagnetic inductor around a cable passing through the opening;
• and
• at least one attachment mechanism is spring loaded in order to apply pressure to a side wall.
