Cabling
When the RG-ES1 series switches are 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 Minimum 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 diameter.
○
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
over10 times greater than its diameter.
⚫
Requirement for the Minimum 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
diameter 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 Bundling up Cables
○
Before cables are bundled, mark labels and stick the labels to cables wherever appropriate.
○
Cables should be neatly and properly bundled in the cabinet without twisting or bending, as shown in
