Cabling Recommendations

During installation, route cable bundles upward or downward along the sides of the rack
depending on the actual situation in the equipment room. All cable connectors should be
placed at the bottom of the cabinet rather than be exposed outside of the cabinet. Power
cords 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 power cable, communication cable, or flat cable should be
○
over five times greater than their respective diameters. The bend radius of these
cables that is often bent or plugged or unplugged 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 minimum bend radius of a high-speed cable, such as an SFP+ cable should be
○
over five times the overall diameter of the cable. If the cable is frequently bent,
plugged or unplugged, the bend radius should be over 10 times the overall
diameter.
Precautions for Cable Bundling

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 Figure 7-1.
