Appendix D Cabling Recommendations in Installation
When RG-S8600 series switches are installed in standard 19-inch cabinets, the cables are tied in the binding rack on the
cabinet by the cable management bracket, and top cabling or bottom cabling is adopted according to the actual situation
in the equipment room. All cable connectors should be placed at the bottom of the cabinet in an orderly manner instead of
outside the cabinet easy to touch. Power cables are routed beside the cabinet, and top cabling or bottom cabling is
adopted according to the actual situation in the equipment room, such as the position of the DC power distribution box, AC
socket, or lightning protection box.
Requirement for the minimum cable bend radius

The bend radius of a power cord, communication cable, and flat cable should be greater than five times their
respective diameters. The bend radius of these cables that often bend or suffer removal/insertion should be greater
than seven times their respective diameters.

The bend radius of a common coaxial cable should be greater than seven times its diameter. The bend radius of this
type of cables that often bend or suffer removal/insertion should be greater than 10 times its diameter.

The bend radius of a high-speed cable (SFP+ cable, for example) should be greater than five times its diameter. The
bend radius of this type of cables that often bend or suffer removal/insertion should be greater than 10 times its
diameter.
Requirement for the minimum fiber bend radius

The diameter of a fiber tray to hold fibers cannot be less than 25 times the diameter of the fiber.

When moving an optical fiber, the bend radius of the fiber should be equal to or greater than 20 times the diameter of
the fiber.

During cabling of an optical fiber, the bend radius of the fiber should be equal to or greater than 10 times the
diameter of the fiber.
Precautions for Bundling up Cables

Before bundling up cables, fill in labels correctly and paste them on proper positions of cables.

Cables should be bundled up in straightness and tidiness, without wind-ups and bends. As shown in figure D-1.
Figure D-1 Bundling up cables (1)

Cables of different types (such as power cords, signal cables, and grounding cables) should be separated in cabling
and bundling. When they are close, crossover cabling can be adopted. In the case of parallel cabling, power cords
and signal cables should maintain a space equal to or greater than 30 mm.

The binding rack and cabling slot inside and outside the cabinet should be smooth, without sharp corners.

The metal hole traversed by cables should have a smooth and fully rounding surface or an insulated lining.

Proper buckles should be selected to bundle up cables. It is forbidden to connect two or more buckles to bundle up
cables.
