Appendix D Cabling
When the RG-S5760C-X switch is installed in a standard 19-inch cabinet, secure the cables around the cable
management brackets. Top cabling or bottom cabling is adopted according to the actual situation in the equipment room.
All transferred cable connectors should be placed at the bottom of the cabinet in an orderly manner instead of outside the
cabinet that is 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 positions of the DC power distribution box, AC
socket, or lightning protection box.
Requirement for the M inimum Cable Bend Radius
The bend radius of a fixed power cord, network cable, or flat cable should be over five times greater than their
respective diameters. The bend radius of these cables that are often bent or plugged should be over seven times
greater than their respective diameters.
The bend radius of a fixed common coaxial cable should be over seven times greater than its diameter. The bend
radius of the common coaxial cable that is often bent or plugged should be over 10 times greater than its dia meter.
The bend radius of a fixed high-speed cable (such as SFP+ cable) should be over five times greater than its diameter.
The bend radius of the fixed high-speed cable that is often bent or plugged should be over 10 times greater than its
diameter.
Requirement for the M inimum Fiber Bend Radius
The diameter of a fiber tray to hold fibers should be over 25 times greater than the diameter of the fiber.
When an optical fiber is moved, the bend radius of the fiber should be over 20 times greater than the dia meter of the
fiber.
During cabling of an optical fiber, the bend radius of the fiber should be over 10 times greater than the diameter of
the fiber.
Precautions for Cable Bundling up Cables
Before bundling cables, correctly mark labels and stick the labels to cables where appropriate.
Cables should be neatly and properly bundled in the cabinet without twisting or bending, as shown in Figure D-1.
