cords are routed beside the rack, and top cabling or bottom cabling is adopted according to the locations of the
DC power distribution box, AC power socket, or surge protection box in the equipment room.

Requirements for the Minimum Bend Radius of Ethernet Cables
○
The bend radius of a fixed power cord, Ethernet 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.

Requirements for the Minimum Bend Radius of Optical Cables
○ The diameter of a fiber splice tray to hold fibers should be over 25 times greater than the diameter of the
fiber.
○
When an optical cable is moved, the bend radius of the optical cable should be over 20 times greater
than the diameter of the optical cable.
○ During cabling, the bend radius of the optical cable should be over 10 times greater than the diameter of
the optical cable.

Precautions for Bundling up Cables
○
Before cables are bundled, mark labels and paste the labels to cables.
○
Cables should be neatly and properly bundled in the rack without twisting or bending.
Figure 7-9 Bundling Up Cables (1)

Cables of different types (such as power cords, signal cables, and grounding wires) should be separated in
cabling and bundling. Mixed bundling is not allowed. When they are close to each other, you are advised to
adopt crossover cabling. In the case of parallel cabling, maintain a minimum distance of 30 mm (1.18 in.)
between power cords and signal cables.

The cable management brackets and chute inside and outside the rack should be smooth without sharp
