Hardware Installation and Reference Guide
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 often bend or suffer removal/insertion should be over seven times
greater than their respective diameters.
After cabling is fixed, the bend radius of a common coaxial cable should be over
○
seven times greater than its diameter. The bend radius of this type of cables that
often bend or suffer removal/insertion should be over 10 times greater than its
diameter.
The bend radius of a high-speed cable (such as SFP+ cable) should be over five
○
times greater than its diameter. The bend radius of this type of cables that often
bend or suffer removal/insertion should be over 10 times greater than its diameter.
Precautions for Cable Bundling

Before cables are bundled, correctly 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 7-4.

Cables of different types (such as power cables, signal cables, and ground cables)
○
should be separated in cabling and bundling. Mixed bundling is disallowed. When
they are close to each other, it is recommended to adopt crossover cabling. In the
case of parallel cabling, maintain a minimum distance of 30 mm between power
cables and signal cables.
