Computer room finishing

Organizing the circuit is also an important part of organizing the computer room. Why should the circuit be organized? Because it corresponds to the port during later maintenance, this is the ultimate goal of the neat circuit. The comprehensive wiring level of the network engineer is also mainly due to his labeling. A reasonable and effective cable layout plays an important role in saving electricity, saving energy, reducing space, and improving air convection in the finishing of the computer room.
Generally, the general wiring system requires the distance as short and tidy as possible and arranged in an orderly manner. The specific methods are "field" and "well". Among them: "field" is more suitable for the layout of the circular machine room, and "well" is more suitable. It is arranged in the vertical and horizontal computer room. Its location can be arranged under the floor and the ceiling, each with its own characteristics, which are explained below:
1. Floor wiring: This is the most common wiring method. It makes full use of the space under the floor, but pay attention to water leakage, rodent damage and heat dissipation under the floor, and also ensure that the corresponding threading holes are cut under each machine room cabinet. (Including floor and trunking).
2. Ceiling wiring: This wiring method is particularly suitable for computer rooms that often need wiring. It is also very popular at present. In this method, the ceiling contains various wiring power sources and weak current wiring. The corresponding threading holes (including the floor) are cut above each cabinet. And wire trunking), of course, you must also pay attention to water leakage, rodent damage, and heat dissipation.The specific wiring content includes: strong current wiring, weak current wiring, and ground wiring.The strong current wiring and weak current wiring are all placed in the metal wiring groove.The specific metal The size of the wiring trough can be based on the amount of wire and consider leaving a certain margin (generally 100 × 50 or 50 × 50). The distance between the strong wire trough and the weak wire trough should be kept at least 5cm or more. Cross to prevent mutual electromagnetic interference. The following will be explained one by one:
Strong current wiring
  • 1.Strong-power wiring: When carrying out strong-current wiring in the decoration of the new computer room, it should be arranged according to the layout of the entire computer room and the capacity of the UPS. Near each cabinet and equipment in the plan, arrange corresponding power outlets. The capacity of the outlets should be It is determined according to the power of the connected equipment, and there is some redundancy, usually 10A or 16A. The cable diameter of the power supply should be based on the capacity of the power outlet and leave a certain margin.
  • Weak current wiring
  • 2. Weak current wiring: The weak current wiring mainly includes coaxial thin cables, super five category network cables and telephone lines. When wiring, pay attention to the corresponding cables behind each cabinet and equipment, and consider future development needs. Various cables should be tied with cable ties.
  • Ground wiring
  • 3. Ground wiring: Since the new computer room is full of high-performance computers and network communication equipment, there are strict requirements for grounding. Grounding also eliminates public impedance, prevents capacitive coupling interference, protects the safety of equipment and personnel, and ensures the stability of the computer system Important measures for reliable operation. Copper bars for signal grounding should be arranged under the floor of the equipment room for various grounding needs in the equipment room. The copper bars are then connected to the weak electrical signal grounding system there by special lines. When wiring for weak electricity, In order to ensure the transmission rate and the stability of the network, the following points should also be noted:
  • 1.If there are extra cables between the two endpoints, they should be cut off according to the required length, and should not be rolled up and bundled (the longer the twisted pair, the worse the transmission quality, and the longer it is. (Cable will cause some difficulties for finishing).
    2.The distance of the unwound wire segments at the connector of the cable should not exceed 2cm, and too long will cause large near-end crosstalk (the twisting requirements of twisted pair wires are very strict, and the winding density will greatly affect the Transmission quality).
    3. At the connector, the outer protective layer of the cable needs to be pressed inside the connector and not outside the connector. Although the entire cable will be stressed when the cable is subjected to external tension, if the outer protection is laminated outside the connector, then The force will be mainly the metal part of the cable and connector.
    4.In the construction of cable wiring, there is a certain limit on the tensile force of the cable, usually about 9kg. Excessive tensile force will destroy the uniformity of the twisted pair of cables.
    5.Because the type 6 cable is thicker than the general type 5 cable, in order to avoid the entanglement of the cable (especially at the elbow), pay attention to the filling degree of the pipe diameter when designing the pipeline. It is advisable to put 2 types of line
