Integrated wiring is a modular, highly flexible information transmission path within buildings or between buildings. Through it can voice equipment, data equipment, switching equipment and various control devices and information management systems connected, but also to make these devices and external communication network connected to the integrated wiring. It also includes all cables and associated connections between the point of connection of the building's external network or telecommunications line and the application system equipment. The integrated wiring consists of different series and specifications of components, including: transmission media, related connection hardware (such as patch panels, connectors, sockets, plugs, adapters) and electrical protection equipment. These components can be used to build a variety of subsystems, each with its own specific purpose, not only easy to implement, but also smoothly upgrades as the needs change.
Let's look at the relevant items that need to be noticed in the three aspects of comprehensive wiring design drawing, integrated wiring construction and the comprehensive wiring maintenance and management in order to ensure the smooth flow of the network.
1, clear user needs. In the process of designing the integrated wiring diagram, we first need to clarify the needs of customers, make a prediction on the future needs, and then design the structure chart. All factors must be factored into the design, as well as the building and communications environment, the proper topology of the communications network, and the media used to be compatible with most manufacturers and equipment.
2, the hardware should be compatible. Cabling equipment choice, try to use the same manufacturer's products, so as to minimize the high-end and low-end or even the same level of incompatibility between different devices. In addition, it is recommended not to excuse the convenience or cheap to choose some other network infrastructure materials or equipment. Such as jumpers, panels, cable and so on. These things in the wiring will be placed in the ceiling or wall, the problem is difficult to solve. At the same time, even branded products are recommended to test the quality with professional tools before installation.
3, anti-magnetic. Why electromagnetic equipment can interfere with the network transmission speed? Because in the integrated wiring network cable is the electrical signal, and high-power electrical appliances will produce a magnetic field near the magnetic field will play a role in the vicinity of the network cable to generate a new electric field, naturally There will be signal weakened or lost, in addition, the need to be aware of is to prevent interference In addition to avoiding interference sources, the network cable connector is also crucial to the way, whether it is 568A or 568B standards to make the network cable must be Assurance 1 and 2, 3 and 6 are two pairs of cores, so as to have a strong anti-interference ability. Structured wiring must be designed in advance the line route, away from the large radiation equipment and a large source of interference.
4, the line should be properly. When we finished structured cabling work should be the excess wire and equipment away, to prevent other users use these devices casually. In addition, the user to use a towed wire thread such devices can also cause a broadcast storm in the network, so integrated wiring to follow a strict management system is necessary. After cabling do not leave any parts, because users are generally not familiar with the network, when there is a problem is very likely to be ill and medicine, see the extra equipment will be casually used to make the problem worse.
5, according to the specifications of the cable connection. It is well known that there are many kinds of network cables, such as crossover cables, straight cables, etc. Different cables have different uses in different situations. If you confuse the type of random use will appear network barrier situation. Therefore, structured cabling must pay special attention to distinguish the type of cable. Cable does not meet the requirements of the network will lead to the problem.
Integrated cabling experience: Although many network devices support DIP jumper function, which means that no matter you are connected to the line or the line, it can be used normally. But sometimes the device does not have the DIP function, only you pay special attention to the wiring connection type, in order to avoid unnecessary failure.
6, cooling. High-temperature environment, the device is always frequently failure. Why does this happen? When the CPU fan cooling poor computer systems often crashes or automatically restart, integrated wiring in the network equipment is even more so, high-speed operation of the CPU and core components need to work in a suitable environment, temperature too High will damage them. Equipment cooling work must be done, especially for the core equipment and servers, they need to be placed in a dedicated room for management, and also need to be equipped with cooling devices such as air conditioners.
7, leave enough network access points. Many times in the integrated wiring process did not consider the future upgrade, the number of network interfaces is very limited, just enough for current employees, if later new employees or company structure changes, then the above problems. Therefore, in the structured wiring need to set aside in advance double the network access point.
The development of the network is very rapid, a few years ago is still working for the desktop to 10Mbps, and now is 100Mbps, or even 1000Mbps to the desktop. The scalability of the network needs our attention, no one would like to use only 2-3 years of wiring system renovation, expansion, so it is important to set aside the surplus access point, so as to meet the needs of future upgrades.
All in all, the integrated wiring system is also forward-looking, so when carrying out the project, we must consider it comprehensively. In addition, the majority of integrated wiring project by the construction staff manual operation, often can not use the machine means. Even if carefully, some failures are still inevitable, so laying wiring in the integrated wiring is still in need of technical checks, conscientiously apply the precautions to the actual construction, to ensure that the integrated wiring works in an orderly manner.
