Common Mistakes In Selecting Industrial Network Switches

Industrial Switch is also called industrial Ethernet switch or industrial network switch, which is the Ethernet communication equipment applied to industrial Internet and industrial digital intelligent control field. Due to the standard TCP/IP network adopted, it has good openness, wide application, high performance and high reliability, and Ethernet communication technology has become the main communication standard in industrial control field. At present, the industrial switch is a very common kind of switch equipment. When we purchase the industrial switch, many people have made mistakes, resulting in choosing low-quality equipment, which cost a lot of money.

1、 Pursue multi ports

Many users often measure the expansion performance of the industrial switch according to the number of ports of the industrial switch; In the eyes of these people, the more ports an industrial switch has, the stronger its expansion function will be, and the overall performance of the industrial switch will be superior. The higher the grade and quality of such industrial switches will be. As a result, many people do not go out from their actual situation, and their slogan is "if you want to buy, you should buy more ports"; However, the more ports an industrial switch has, the more expensive it will be. But in fact, if the network scale is not large, and the pursuit of multi ports industrial switches blindly, not only many ports can not play a role, but also cause a great waste of funds.

2、 Pursue high speed

The speed of network transmission is often a problem that many users are very concerned about. Is it because the higher the speed of the industrial switch, the faster the data transmission speed of the network? In fact, the data transmission speed of the network is not only related to the switch, but also related to other related network equipment. This requires that when selecting an industrial switch, we should not go in for one-sided high-speed, but should pay attention to maintaining speed matching with other equipment.

3、 Pursue cheapness

As the price of industrial network switches continues to decline, their technical content is also incomplete, so the stability of industrial network switches is challenged. Therefore, if you want to build a successful LAN, you must ensure that the overall performance of the network is stable, and the stability of the industrial network switch is the most direct embodiment of the stability of the LAN.

In order to avoid selecting industrial network switches with poor stability, you must conduct some simple tests on site when selecting switches. For example, connect the industrial network switch to the network, and then transmit some programs or images with large capacity on the network to see if the data transmission process is fast or slow. If this phenomenon occurs, it is mostly due to the unstable performance of the switch. If you encounter an industrial network switch with unstable performance, even if the price is cheap, don't choose it!

4、 Ignore the heat dissipation performance of industrial network switches

The heat dissipation performance of the industrial network switch will also affect the stability of the transmission performance of the industrial network switch. As the industrial network switch operates 24 hours a day for a long time, in this case, the heat dissipation of the industrial network switch is particularly important. Once its heat dissipation performance is poor, the overall transmission performance of the network will be greatly affected.

At present, in order to attract customers with low prices, many industrial network switch manufacturers are willing to reduce costs to achieve their goals in disguised form. The most common way to reduce costs is to simplify the cooling equipment as much as possible and use cheap enclosures.

5、 Ignore the management function of industrial Ethernet switch

Considering that the industrial Ethernet switch is a kind of equipment with strong durability, and it is not easy to be damaged when you buy it, you should try to ensure that its functions will not fall behind in three to five years, even if you can not do it all at once. This requires you to consider the management and control functions of the industrial Ethernet switch when selecting the industrial Ethernet switch.

If your network has a certain scale, and you want to be able to grasp the dynamic changes in the network at any time, you can consider selecting an industrial Ethernet switch with network management function. After all, using this type of industrial Ethernet switch will help you quickly eliminate various network failures. Of course, if the price of an industrial Ethernet switch with network management is not much different from that of an ordinary switch, you can choose an industrial Ethernet switch with network management from the perspective of future upgrades.

In a word, when choosing an industrial network switch, we should first understand the basic professional knowledge of the industrial network switch. The expensive one is not necessarily a good one. On the basis of ensuring the quality of the industrial network switch, we should comprehensively consider the working environment, whether redundancy is required, network management and non network management, future maintenance and scalability and other factors, so as to choose an industrial network switch with high cost performance, Only in this way can we work better.
