How To Improve The Reliability Of The Industrial POE Switch?

With the progress of science and technology and the development of information, all industries are gradually inseparable from the existence of electricity, because every kind of electrical appliance needs electricity to operate. But once our phones, network videos and wireless routers are cut off for no reason, where should we find the right power supply system at once? So people also have a vision. In view of this situation, we have already invented the poe switch, a typical Ethernet power supply system, to better meet the requirements of the video monitoring field for network video transmission.

POE (Power Over Ethernet) refers to the existing Ethernet Cat 5 Without any change to the cabling infrastructure, the technology that can provide DC power for such devices while transmitting data signals for some IP based terminals (such as IP phones, wireless LAN access points AP, webcams, etc.). POE switch is a switch that supports Ethernet power supply.

Technically, POE has been developed for many years, so it is in a relatively stable stage. The power supply of standard POE is sufficient and stable. However, at present, due to low market cost, poor quality of PoE switches or wires, or unreasonable scheme design, the maintenance workload of PoE powered projects will be particularly heavy, while network monitoring projects are different from ordinary network generic cabling, with large data transmission volume, high power, and the requirement of all-weather uninterrupted work, which leads to the view that PoE power supply is unstable. Keep in mind that this is not the reason for POE power supply, it is a human factor.

The industrial POE switch has a full range of functions, providing you with great convenience and speed. In order to make the industrial POE switch more reliable, you have taken great pains. So, what can you do to improve the reliability of the industrial POE switch?

1. Transmission distance: Although PoE power supply is convenient and convenient, the distance between parallel lines of power supply cannot exceed 100 meters. There are not only power signals but also data signals in the network cable. The power signal has no distance limit and can reach 200 meters or 500 meters, but the data transmission is not good. It has consumption. The longer the distance is, the greater the consumption. In order to better ensure the best actual effect of the video interface, according to the data transmission specification, the PoE power supply distance cannot exceed 100 meters.

2. Improper selection of industrial PoE switches: that is, the quality of the selected industrial PoE switches is unqualified, or the model and specification are incorrect. In a  large or medium-sized monitoring system project or a site with very high regulatory requirements, selecting an industrial PoE switch from an unknown small manufacturer is likely to cause problems, because the product quality and characteristics cannot be guaranteed!

In addition, although a better industrial PoE switch is selected, it is also bad if the model is not selected correctly. For example, a region that should use a full gigabit PoE switch, but uses a 100M  or a mixture of 100M and gigabit PoE switches, will cause data transmission delays, jams, and losses. This is the network bandwidth problem of PoE switches.

3. Finally, the industrial PoE switch is just a power supply machine, which will undoubtedly involve power supply. If the power supply power is too small, the output power of high-power front-end equipment such as ball machine cannot meet the requirements.

Summary: How to improve the reliability of industrial PoE switch applications? In fact, it is not difficult: high-quality network cable+PoE switch with excellent performance+suitable power supply distance+suitable power supply model+reasonable project scheme.
