The embodiment of the construction technology level of the wiring in the computer room is the embodiment of the construction level of an engineer. The place where the owner usually visits is the computer room, so the wiring construction of the computer room is the top priority. How can we improve the construction level of the wiring in the computer room?
The wiring in the computer room should not be done arbitrarily. The actual wiring of the network cable should be carried out on the site. When the computer room is newly built or rectified, the network cable and optical fiber jumper are not allowed to use the same cable management or cabinet cable management slot, and should be managed separately in their own dedicated cable management device or cabinet. Wiring is carried out in the slot, and the equipment power cord, network cable and optical fiber jumper are not allowed to be intertwined with each other, and should be bundled separately from the network cable and optical fiber jumper. If the network cable is parallel to the strong current line, the network cable and the strong current line should be kept at an appropriate distance. When arranging and bundling the network cable and the optical fiber jumper, the fixed rope is strictly prohibited to be tied too tightly.
