Abstract

A cable management system is disclosed including a frame that can be attached to an equipment rack. Cable guides can be mounted on the frame to align a plurality of cables adjacent to each other. A cable tray is positioned adjacent the cable guides. The combination of the frame, the cable guides, and the cable tray can be positioned alongside a component in the equipment rack to route the cables around an outer edge of the component.

Claims

1. A cable management system comprising:

a first cable guide including;

a platform;

a cable slot on the platform;

a cover closable over at least a portion of the cable slot; and

a curved guide member on the platform, wherein the curved guide member is configured to prevent a cable from being bent past an allowable bend radius, wherein the first cable guide is labeled to indicate the bend radius of the curved guide member.

2. The system of claim 1 wherein the first cable guide further includes a guidepost adjacent the cable slot.

3. The system of claim 1 further comprising cushion material in the cable slot.

4. The system of claim 1 wherein the first cable guide includes a latch to retain the cover in closed position over the cable slot.

5. The system of claim 1 wherein one portion of the cover is hinged to the first cable guide.

6. The system of claim 1 wherein the first cable guide is labeled to indicate cable routing direction.

7. The system of claim 1 further comprising a retaining tab coupled to the curved guide member, wherein the tab is configured to retain the cable in place in at least one direction.

8. The system of claim 1, wherein the curved guide member allows the cable to be routed in one of either two directions.

9. The system of claim 1, wherein the first cable guide further includes a second guide member with a curved portion on the platform, and the curved portion of the second guide member is configured to prevent a cable from bending past the allowable bend radius.

10. The system of claim 1 further comprising:

a frame including at least one mounting area for attaching the first cable guide to the frame.

11. The system of claim 10, wherein the first cable guide is configured with a tab and mounted to the frame by engaging the tab in a slot on the frame.

12. The system of claim 10, wherein the frame further comprises a cable tray adjacent the at least one mounting area.

13. The system of claim 10, wherein the frame includes at least one attachment member configured to attach the frame to an equipment rack.

14. The system of claim 10, wherein the combination of the frame with the first cable guide attached is configured to fit in a space between components in an equipment rack.

15. The system of claim 12, further comprising:

a second cable guide attached to the cable tray, wherein the second cable guide includes retaining members configured to route the cable around the outer edges of components in an equipment rack.

16. The system of claim 15, wherein the second cable guide includes a curved portion configured to prevent the cable from bending past the allowable bend radius.

17. The system of claim 15, wherein the second cable guide includes a strap to further retain the cable in place relative to the second cable guide.

18. The system of claim 15, wherein the second cable guide attaches to an end of the cable tray and is configured to allow the cables to be routed in one direction or another direction.

28. The system of claim 1, wherein the first cable guide is aligned directly with rows of connection ports of a component installed in an equipment rack to eliminate crisscrossing cables and to allow particular cables to be removed and replaced without disturbing other cables.

29. The system of claim 1, wherein the number of the first cables guides is scaled to the number of connection ports and corresponding cables required to communicate with a component.

30. The system of claim 1, wherein the first cable guide is configured for a mixture of several different types and sizes of cable, and different allowable bend radii.

31. The system of claim 1, wherein the first cable guide is configured with materials that help shield adjacent cables from interference from other cables.

19. A cable management apparatus, comprising:

a frame attachable to an equipment rack;

a plurality of first cable guides mounted on the frame, wherein the first cable guides are configured to align a plurality of cables adjacent to each other; and

a cable tray positioned adjacent the first cable guides, wherein the combination of the frame, the first cable guides, and the cable tray is positioned along one side of a component in the equipment rack, and the first cable guides and cable tray are configured to route the cables around an outer edge of the component.

20. The apparatus of claim 19, further comprising:

a cover positionable to retain the cables in the first cable guides.

21. The apparatus of claim 19, further comprising:

a second cable guide attached to a side of the cable tray, wherein second cable guide includes a curved portion with a radius greater than or equal to a minimum bend radius for the cables.

22. The apparatus of claim 19, wherein at least a portion of the first cable guides are curved to route the cables to the cable tray without violating a minimum bend radius for the cables.

23. The apparatus of claim 19, wherein the first cable guides are configured to route the cables in either of two directions.

24. The apparatus of claim 19, wherein the first cable guides include markings to indicate routing direction.

25. The apparatus of claim 19, wherein the first cable guides are configured as a plurality of cartridges that are removable from the frame.

26. The apparatus of claim 25, wherein at least one of the cartridges is removable from the frame independently of the other cartridges.

27. The apparatus of claim 25, further comprising a plurality of covers, wherein one portion of each cover is movably attached to a portion of a corresponding cartridge, and another portion of each cover includes a latch to hold the cover in a closed position to retain the cables in position.

32. The apparatus of claim 19, wherein the cable tray and the frame are configured to allow components to be removed from the equipment rack while the frame is attached to the equipment rack.

33. The apparatus of claim 19, wherein the cable tray is attachable to the frame.
