Summary of experience in installing network cabinet equipment

  
                  A wiring cabinet is mounted in the cabinet

plants, tend to have equipment cabinet (the installation of public broadcasting, security, industrial equipment, etc.), a telecommunications cabinet (installed computer network devices, optical end boxes and other equipment), server Types such as cabinets (servers for installing computers) and wiring cabinets (for patch panels and computer network equipment for integrated wiring). In the cabinet manufacturer's factory, most of the equipment cabinets and server cabinets are produced, and the wiring cabinets dedicated to the integrated wiring system are rarely produced. Therefore, many engineering companies actually use equipment cabinets or communication cabinets instead of wiring cabinets. The wiring cabinet is a specially customized cabinet for the integrated wiring system. The special point is that it adds some accessories unique to the wiring system and puts special requirements on the layout of the power supply. For example, on the left side of the rear of the cabinet, install a front fully enclosed metal power cable slot that extends from the bottom of the cabinet to the top of the cabinet. The topmost socket is dedicated to powering the fans. The purpose of installing a fully enclosed metal power cord slot vertically is to avoid power interruptions to the horizontal twisted pair. In most cabinets, a horizontally mounted power strip is used, which allows a portion of the power outlet to be less than 200 mm apart from the horizontal twisted pair, so it is not an ideal power layout.

tie plate line: right rear side of the cabinet, mounting two iron 100mm wide, 10mm board a circular opening of 5 × 100mm intervals in the vertical direction, a length from the cabinet iron The bottom plate to the top plate. Also, install the same iron plate on the left rear side (between the power cable slot and the column). The exposed surface of the wiring board is required to be flat and burr-free so as not to damage the cable. The cable tie plate is in close contact with the grounded metal power cable slot, and only the optical cable and the large logarithmic cable for voice transmission can be laid on this side; BR>
Chassis: Open a 300×200mm rectangular inlet hole at the back and wrap it with rubber to avoid damage to the cable. At a distance of 90 mm above the hole, a partition can be installed to look good in the cabinet.

ground: in the middle of the enclosure from a low vertical mounting a top grounded copper strips, 2U open an isometric M6 coarse screw hole on the copper tape at intervals so as to be close to ground shielded patch panel, wherein The bottom screw hole is used for the cabinet to draw the ground wire. Each metal component of the cabinet should be grounded to achieve the overall grounding of the cabinet. The grounding of the cabinet should be connected to the grounding copper bar of the equipment room through the grounding lead wire on the grounding copper strip.

at both sides of the cabinet should each have two attachment bolts and holes, and connected with bolt and, when the number of identical secret level wiring cabinet placed together side by side, and connected preferably used Bolts connect the cabinets together.

distribution frame with mounting screws to be filled (for 42U rack, the sleeve 84 with mounting screws needed), in order to ensure to the patch panels, network devices and all use the same empty panel mounting screws, so In order to ensure the beauty of the front of the cabinet.

removable enclosure should be configured to facilitate handling and construction. The cabinet can be disassembled into 6 pieces (front, rear, up, down, left, right) for easy packaging and transportation. After arriving at the scene, it can be reassembled into cabinets by screws. When the height of the machine room door is limited, the distribution frame in the equipment room can be used for integrated wiring, and the network cable is driven into the distribution frame by the color line, and the cable management frame The wiring in the cabinet can be more beautiful, the information socket is fixed on the wall, there is a module inside, and the network cable is also driven into the module according to the color, and then placed in the information socket. When the Internet is connected, the network cable is inserted into the computer network card at one end. Just plug it into the information outlet.

Second, the role distribution frame

communications room and equipment room is like the nerve center cabling system, to take over the work area from the horizontal cable on the patch panel here with Interconnect or cross-connect to the device port. The inter-matching or cross-connection of cables is achieved by modular cables or jumpers.

patch can be divided into its user interface modular patch (Patch Panel) and IDC patch panels, modular patch panels jumper modular (RJ-45 jumpers) For line connection, IDC type patch panels can be modular IDC jumper cables (commonly known as "duck mouth jumpers" such as BIX-BIX, BIX-RJ45 jumper cables), and jumper wires (Jumper Wire, Crossconnect Wire) Make a line connection. Modular jumpers and IDC jumpers are easy to plug and unplug, while cross-connect jumpers require a dedicated crimping tool (such as a BIX crimping knife) to push the jumper into the clip of the IDC connector.

patch installation can be divided by a wall-mounted or frame-mounted, modular patch panels are typically designed to be rack-mounted installation, the wall mount attachment and the like may also be wall mounted; Fair IDC-style patch panels are typically designed for wall mounting and can be used for rack mounting with some rack mount accessories or special designs.

Third, the cable management cabinet

cable management devices may be mounted on the wiring and provided with a front end of the frame in the horizontal direction jumper cable management. The cable management frame simplifies the planning and installation of the cross-connect system. Simply put, it is to clear the network cable and has no direct relationship with the network, which is convenient for future management.
