Detailed explanation of the installation process of communication equipment, indoor installation

The installation process of communication equipment includes indoor and outdoor. The indoor includes five aspects: cabinet, signal line, terminal, power line and grounding line, and equipment installation process environment; outdoor is composed of four parts: iron tower, antenna, feeder, and lightning protection grounding. Composition. The following is a detailed explanation of each point of indoor installation.

1. Cabinet installation: The surface of the entire row of cabinets should be on the same plane, and the arrangement should be neat and close. The frame part should not be deformed. Otherwise, it will affect the appearance of the equipment. The rack fixing should be reliable and meet the seismic requirements on the engineering design documents. All expansion screws used for fixing should be installed and tightened, the installation sequence of insulating gaskets, large flat washers, and nuts (bolts) should be correct, and the mounting holes of brackets or feet should be well-matched with expansion screws. The insulating gasket should be installed between the bracket and the ground and should meet the insulation requirements. When using the customer-made base for installation, it should meet the customer's requirements. All inlets and outlets should be closed. The row and column labels of the cabinet should be affixed firmly, neatly, and cleanly. If the cabinet is designed with a label, the label should be affixed to the virtual frame. The ESD wrist strap should be inserted into the ESD mounting hole in the cabinet. The board should be inserted and removed smoothly, the board screws should be properly tightened, and the screws should be intact. False handlebars and panels should be installed as required. There should be no extra wire clips, screws, and other debris on the inside, bottom, and top of the cabinet. There should be no extra wire clips, screws, and other debris on the inside, bottom, and top of the cabinet.

2. Installation of signal wires: The signal wires should be free from damage, breakage, and intermediate joints. The signal line connector should be clean and undamaged. The connector made on-site should be standardized, and the connection should be reliable. Each customer line and trunk line must pass the continuity test. Signal cables cannot be routed on the cooling holes of the cabinet. Cable bindings should be evenly spaced, moderately tight, and neatly tied. After tying, the excess part of the wire buckle should be cut off without burrs. The cable label should be filled in correctly, pasted reliably, and the label position should be neat and straight. It is recommended to stick the label 2cm away from the plug. Labels can also be made uniformly according to customer requirements. When using a cable ladder, the cables should be fixed on the beam and bound into a rectangle (single-core cables can be bound into a circle). If the distance between the cable ladder and the top of the cabinet is greater than 0.8m, a cable-running ladder should be installed on the top of the cabinet. When the cables are laid in multiple rows under the floor, the height cannot exceed 3/4 of the clearance under the anti-static floor. The corners of the signal cables should be smooth, and necessary protection measures should be taken when fixing angular structures. The loose wires near the user cable plug at the device end should be tied smoothly and neatly. The user's cable should be smooth and leave a margin. After the MDF end clip is peeled, it should be wrapped with tape or covered with a heat-shrinkable tube. Cables should be laid out neatly without any crossover, leaving a margin. The cable label should be pasted neatly and should be pasted 2CM away from the plug. HW cables and NOD cables must be neatly bundled so as not to affect the storage of other cables and future expansion. The turning radius of the coaxial cable should not be less than 4cm. When laying pigtails, the bends should not be too tight or intertwined. Pairs of pigtails should be tied neatly and with appropriate strength.

Pigtails can be freely twitched in the wire buckle and cannot be turned at right angles. There should be no other cables or objects on it after placement.

When the pigtails are laid out of the cabinet, protective measures, such as adding protective sleeves or grooves, are required. The protective sleeve should enter the inside of the cabinet, the length should not exceed 10cm, and the sleeve should be tied and fixed. The incision of the pigtail protective sleeve should be smooth. Otherwise, it should be cut-resistant with insulating tape. The pigtail connection points should be clean and free of dust. The unused fiber heads and single-board optical ports should be protected with protective caps (plugs). If cleaning, follow the company's requirements.

3. Terminal installation: The network management system should be installed correctly and work normally. Labels should be affixed to terminals and alarm boxes in accordance with specifications and should be easy to maintain. The supporting cables of the terminal, the operation console, and the alarm box should be rationally bundled. Excess cable ties should be cut off at the root without any spikes.

4. Power wire and ground wire: The power wire and ground wire should be connected correctly and reliably. All metal enclosures and racks in the server cabinet should be properly and reliably grounded to the protective ground. The ground wire of the cabinet door should be connected correctly and reliably. The equipotential cables of the parallel cabinet and the same module cabinet should be connected correctly and reliably. The PGNDs between the server cabinet and the communication equipment host should be connected to each other by short wires.

The protective ground wires of MDF and DDF should be firmly connected, and the protective ground wires between adjacent racks should be connected to each other and connected to the protective ground bar of the client nearby. The power and ground wires must use full-ended copper core cables without any connectors in between. The wire diameter of the equipment power cable, ground wire, and equipotential wire between cabinets should meet the equipment power distribution requirements. Power cables, ground cables, and signal cables should be laid out separately. The distance between the power cable, ground cable, and signal cable outside the cabinet should meet the design requirements. Generally, it is recommended that the distance should be greater than 3cm. Power cables or ground cables should be neatly arranged and bound. Power cables and ground cables should be tied smoothly at the corners. The turning position of the power cable and the ground cable should be smooth, and protective measures should be taken when the signal cable is fixed on the angular structure. The copper noses for the power and ground wires should be soldered or crimped securely. The wire lugs and bare wires of the power and ground wires should be wrapped with sleeves or insulating tape, and there should be no exposed copper at the wire lugs or terminals. The flat pads and spring pads should be installed correctly.

5. Equipment installation environment: The computer room should be far away from areas with strong electricity and strong magnetic waves and strong heat sources and should meet the electromagnetic requirements of the computer room. The cleaning of the computer room should meet the requirements of long-term safe operation. The temperature and humidity in the equipment room should meet the requirements for the long-term safe operation of the equipment.

Fire prevention measures should be taken in the equipment room. The DC voltage and capacity of the equipment room must meet the requirements of long-term safe operation.

The above is the detailed content of the installation process of communication equipment for indoor installation.
