How to do network wiring in Chengdu office?

1. Equipment is compatible with the cooperation between different devices, especially when high-end equipment and low-end equipment from different manufacturers are used together, incompatible faults often occur. Using a company's products for all network devices is a good way to avoid such problems, which can minimize the incompatibility between high-end and low-end devices and even different devices at the same level. In addition, if wires with poor quality are used, incompatibility will easily occur. Nanjing Weikang Communication said that you can't choose network basic materials without quality assurance or small brands, such as jumpers, panels and network cables. These things will be placed in the ceiling or wall when wiring, which is difficult to solve after problems occur. At the same time, even the products of big brands should be tested by professional tools or verified through official channels before installation. 2. Residual line management After the structured wiring work is completed, the redundant lines and equipment should be taken away. Weikang Communication believes that this is the best way to prevent ordinary users from connecting these lines indiscriminately. In addition, sometimes users' private use of second-class equipment will also cause broadcast storms in the network, so strict management rules need to be followed when wiring. Don't leave any components after wiring, because users are generally unfamiliar with the network, and when there is a problem, they are likely to go to the hospital in a hurry, and use the redundant equipment casually, making the problem more serious. 3. There are many kinds of standard network cables for wiring, such as twisted pair, crossover cable, through cable and console cable. Different cables have different uses in different occasions. If you use confused types at will, the network will be blocked. Therefore, we must pay special attention to distinguish the types of cables when structuring wiring. If the cable does not meet the requirements, the network will be blocked. Although many network devices currently support the DIP jumper function, that is to say, whether you connect the positive wire or the negative wire, it can be used normally. But sometimes the device does not have DIP function. Only by paying special attention to the wiring type can we avoid unnecessary faults. 4. Extended Interfaces If future upgrades are not considered in the process of structured cabling, the number of network interfaces is limited, just enough for current employees. If new employees come later, or the company structure changes, then there will be great problems in expansion or change. Therefore, it is necessary to set aside twice as many network access points in advance when structuring wiring. As we all know, the network is developing very rapidly. A few years ago, I was still working hard for 100Mbps to the desktop. Now it is 1000Mbps, or even1000 Mbps to the desktop. The development of network needs our attention. No one wants to rebuild and expand the wiring system in only 2 ~ 3 years, so it is very important to leave a backup access point. Theoretically, the access point should have twice the surplus to meet the needs of future upgrades. 5. Anti-high temperature When the CPU fan has poor heat dissipation, the computer system often crashes or restarts automatically. The CPU and core components of high-speed intelligent equipment and network equipment need to run in a suitable working environment, and excessive temperature will cause damage to them. Equipment summer work must be done, especially the core equipment and servers, which need to be managed in a special computer room and equipped with air conditioning and other cooling equipment. 6. Electromagnetic interference Electromagnetic equipment will interfere with the network transmission speed; Because the electric signal travels in the network cable, and a magnetic field will be generated near the high-power electrical appliances, this magnetic field will generate a new electric field when it acts on the nearby network cable, and the natural signal will be weakened or lost. It should be noted that in addition to avoiding interference sources, the connection mode of network cable connectors is also very important to prevent interference. No matter whether 568A or 568B standard is adopted as the network cable, 1 and 2, 3 and 6 are two pairs of cores, which has strong anti-interference ability. In structured wiring, we must design the routing of network cables in advance, away from large radiation equipment and large interference sources.
