How to Choose a Suitable POE Industrial Switch

Poe refers to the technology that provides DC power for such devices while transmitting data signals for some IP-based terminals without any changes to the existing Ethernet Cat.5 cabling infrastructure. This article introduces the interface of the poe industrial switch and how to choose the appropriate poe industrial switch.
 
POE Industrial Switch
 
Poe industrial switch interface introduction
 
At present, the single-port power supply of poe industrial switches has 15.4W and 30W, and the power supply voltage is generally 48V. When choosing a poe industrial switch to supply power to network equipment, the total power supply of the poe industrial switch is a very important indicator, and the power is small. The device is not working. Since poe industrial switches have both data signals and power signals in the network cable when supplying power, in order not to affect each other and to ensure a good power transmission effect, the single-port power supply of related equipment powered by poe industrial switches cannot exceed 30W.
 
How to choose the right poe industrial switch
 
1. Choose according to the power supply standard
 
Determine the power supply protocol (such as 802.3af, 802.3at or non-standard poe) supported by the power receiving terminal (AP or IPC). The poe power supply protocol supported by the industrial switch needs to be consistent with the power receiving terminal. The single-port output power of the 802.3af standard poe industrial switch is 15.4W, and the single-port input power of the 802.3at standard poe industrial switch is 30W. It is recommended to use the 802.3at standard poe industrial switch for the power receiving equipment.
 
In addition to considering the power supply protocol and single-port output power of the poe industrial switch, the overall power of the poe industrial switch needs to be considered. The greater the total power, the stronger the power supply capability.
 
2. Choose according to physical port
 
The ports of poe industrial switches are also divided into numbers, ranging from 4 to 24 ports. Please consider the number of poe power supply ports according to the number of power-receiving terminal devices.
 
3. Choose according to the transmission rate
 
The transmission rate of the poe industrial switch is divided into 100M and Gigabit. It is necessary to consider the good rate that the port needs to support according to the power receiving terminal and business requirements. Under normal circumstances, the performance of gigabit poe industrial switches is better than that of 100 megabits poe industrial switches. If you want to achieve high-definition and smooth effects, you can use gigabit poe industrial switches.
 
4. Choose according to manageability
 
Poe industrial switches are divided into network management poe industrial switches and basic poe industrial switches. Basic poe industrial switches mainly provide poe power supply ports, which do not need to be configured for direct use; network management poe industrial switches can flexibly configure port power supply time and priority while providing poe power supply, and can specify a more reasonable power supply plan.
 
Regarding the issue of poe industrial switches, this article introduces the ports of poe industrial switches and how to choose a suitable poe industrial switch. In short, the power supply of the poe industrial switch is realized through the network cable, which means that the power needs to be transmitted in the network cable. The poe technology can ensure the stability of the existing structured wiring while ensuring the normal operation of the existing network, reducing costs by a large amount.
