A brief discussion on the precautions for comprehensive cabling of communication networks
Integrated wiring is a modular, highly flexible information transmission channel within a building or between building groups.
Integrated wiring that can connect voice equipment, data equipment, switching equipment and various control equipment to the information management system, and also connect these equipment to the external communication network.
It also includes all cables and related connection parts between the connection points of the building's external network or telecommunications lines and the application system equipment.
Integrated wiring consists of components of different series and specifications, 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 various subsystems, each of which has its own specific purpose. It is not only easy to implement, but also can be upgraded smoothly as needs change.
Next, let’s take a look at the relevant matters that need to be paid attention to in the three major aspects of drawing integrated wiring design drawings, conducting integrated wiring construction, and later maintenance and management of integrated wiring to ensure the smooth flow of the network.
1. Clarify user needs
In the process of designing the comprehensive wiring diagram We first need customers to clarify their needs, make a prediction of future needs, and then design a structural diagram.
We must take all factors into consideration when designing, and we must also understand the building and communication environment to determine the design. A suitable communication network topology diagram and the media used should be compatible with most manufacturers and devices
2. The hardware must be compatible
When selecting integrated wiring equipment, try to use products from the same manufacturer. This can minimize incompatibility problems between high-end and low-end equipment or even different equipment of the same level.
In addition, it is recommended not to do it for convenience. Or it is cheaper to choose other basic network materials or equipment.
For example, jumpers, panels, network cables, etc.
These things will be placed in the ceiling or wall during wiring. It is difficult to solve the problem afterward.
At the same time, it is recommended to use professional tools to check the quality before installation.

Anti-magnetic
< p style="padding: 0px 0px 15px; margin-top: 0px; margin-bottom: 0px; border: 0px; line-height: 24px; font-size: 14px; font-family: simsun, Arial; white-space: normal;">Why can electromagnetic equipment interfere with network transmission speed? Because in integrated wiring, network cables carry electrical signals, and magnetic fields are generated near high-power electrical appliances. This magnetic field will act on nearby network cables, generating new The electric field will naturally cause signal weakening or loss. In addition, it is important to note that to prevent interference, in addition to avoiding interference sources, the network The connection method of the cable connector is also crucial. Whether you use the 568A or 568B standard to make the network cable, you must ensure that 1 and 2, 3 and 6 are two pairs of core wires, so as to have strong anti-interference ability.During structured cabling, the network cable route must be designed in advance to keep it away from large radiation devices and large interference sources.

4. Connections must be appropriate
After we complete the structured integrated cabling work, we should take away the excess wires and equipment to prevent other users from using these equipment indiscriminately.
In addition, users may use one-to-two-part cables privately Equipment can also cause broadcast storms in the network, so follow the general wiring instructions It is necessary to follow a strict management system.
Do not leave any components behind after integrated wiring, because users are generally not familiar with the network. When problems arise, they are likely to rush to the doctor and see redundant equipment. Will use it casually, making the problem worse
5. Connect the cables according to specifications
As we all know, there are many kinds of network cables, such as crossover cables, straight-through cables, etc. Different cables have different situations under different circumstances. Different uses.
If the types are mixed and used casually, network failure will occur.
Therefore, special attention must be paid to distinguishing the types of cables when using structured integrated cabling.

If the cables do not meet the requirements, there will be problems with the network.
Comprehensive wiring experience: Although many network devices currently support the DIP jumper function, that is to say, no matter what you connect. Whether it is a front line or a reverse line, it can be used normally.
But sometimes the equipment does not have the DIP function. Only if you pay special attention to the wiring type when connecting can you avoid unnecessary failures.

6. Heat dissipation
In high-temperature environments, equipment always fails frequently.
Why does this happen? When the CPU fan does not dissipate heat well. Computer systems often crash or automatically restart, especially network equipment in integrated wiring. High-speed CPUs and core components need to operate in a suitable working environment. Too high temperatures will damage them.
Equipment cooling must be done, especially for core equipment and servers, which need to be placed in a dedicated computer room for management and equipped with air conditioning and other cooling equipment.

7. Leave enough network Access point
Many times during the comprehensive wiring process Future upgradeability is not considered, and the number of network interfaces is very limited, which is just enough for current employees. If new employees come or the company structure changes in the future, the above problems will occur.
Therefore, in the structure. When wiring, you need to reserve twice as many network access points in advance.
The network is developing very rapidly. A few years ago, we were still working hard to bring 10Mbps to the desktop. Now it is 100Mbps, or even 1000Mbps on the desktop.
We need to pay attention to the scalability of the network. No one wants to renovate and expand the wiring system after only 2 to 3 years, so leave some time. Spare access points are very important to meet the needs of future upgrades
8. Summary
Integrated wiring systems are also forward-looking, so comprehensive considerations must be taken when carrying out project projects.
In addition, most integrated wiring projects are manually operated by construction personnel and cannot be used in many cases. Machine means
No matter how careful you are, some faults are inevitable, so laying lines in integrated wiring still requires technical control, and careful application of precautions to actual construction to ensure that the integrated wiring project proceeds in an orderly manner.
