The biggest bright spot for POE switches is that they can supply power to front-end network devices. This can reduce the amount of network cabling work. Therefore, many project providers are quite interested in POE switches.
The POE power supply module inside the switch is self-adaptive. Only when the connected front-end equipment sends power requirements, the back-end POE switch will transmit the current. This application scenario is mostly on video surveillance cameras, if the front-end camera does not support POE. Power supply, but when the site wants POE power supply, just add a POE separator just like this, this operation will be more convenient!
For POE switches can also be understood, is a switch that supports Power over Ethernet, on the basis of the original Ethernet cabling, for some IP terminals (webcams, wireless LAN) while transmitting, but also to maintain power supply!
POE switch power supply workflow:
1. Check: Because the single-port output voltage of the POE switch is very small, it is necessary to find equipment that meets the requirements when conducting power supply port troubleshooting. There are two types of standards for the Tianbo communication POE switch, IEEE802.3af standard and IEEE802.3at. Standards can be supplied only if the accepted port meets the standard.
2. Classification: In the previous step of the search process, the power supply equipment has been identified. Now the power loss of the equipment should be classified, and the loss of each power supply port should be reasonably arranged so that the power supply of the switch can be normal.
3, switch power supply: For the switch power supply voltage, according to the needs of the site to choose, Tianbo PoE switch single-port power supply maximum 15.4W, the maximum power of 96W, adapt to a variety of environments.
4. Power-off protection: When the front-end device (network camera) is disconnected during the connection process, the POE power supply switch will quickly stop the power supply and detect the connected device.
