Recommendations on Wiring During Installation

7.3
When the device is installed, the connected cables are bundled on the cable binding frame of the cabinet
through the cable management bracket. Choose upper or lower wiring according to the actual situation
of the equipment room. Arrange and place all cable connectors at the bottom of the cabinet (not outside
the cabinet where it is easy to be touched). The power cables are routed from the side of the cabinet.
Choose upper or lower wiring according to the actual situation of the equipment room (locations of DC
power distribution box, AC socket, and lightning resistant box.
Requirements for minimum bending radius of cables

After power cords, communication cables, and flat cables are laid and fixed, their bending radius
○
should be more than 5 times the outer diameter of the cables. For the cables that are often bent
and plugged, their bending radius should be more than 7 times the outer diameter of the cables.
After common coaxial cables are laid and fixed, their bending radius should be more than 7 times
○
the outer diameter of the cables. For the cables that are often bent and plugged, their bending
radius should be more than 10 times the outer diameter of the cables.
The bending radius of high-speed cables (such as SFP+ cables) should be more than 5 times the
○
outer diameter of the cables. For the cables that are often bent and plugged, their bending radius
should be more than 10 times the outer diameter of the cables.
Precautions for Cable Bundling

Before bundling the cables, the labels need to be filled in correctly and affixed to the appropriate
○
positions of the cables.
After the cables are bundled in the cabinet, they should be straight and neatly bundled without
○
twisting or bending, as shown in
Cable bundling diagram (1)
Figure 7-4
Twisted
Different types of cables (power cables, signal cables, such as ground cables) should be routed
○
and bound separately in the cabinet. Do not mix them. When the distance is short, cross wiring
