the HR901-af-2421GS PoE Switch with 24 Port 10/100M PoE + 2 Port Gigabit Ethernet Uplink + 1 Port Gigabit sfp Uplink Port, it’s using high-quality high-speed network ic and the most stable poe chip, poe port meets 802.3af / 802.3at standard, this series of PoE Switch can be 10/100M Ethernet the network provides a seamless connection, and the PoE power port can automatically detect and power the powered devices that comply with the IEEE802.3af / IEEE802.3at standards. The non-poe device intelligently detects no power and only transmits data.
PoE (Power over Ethernet) refers to the technology of providing DC Power supply to some ip-based terminals (such as ip telephone, wireless access ap, network camera, etc.) while transmitting data signals. These devices receiving DC Power supply are called receiving devices.
With simple and convenient installation and maintenance methods and rich business features, it helps users to build a safe and reliable high-performance network. It is mainly located in the core or convergence layer of user networks such as industrial parks, buildings, factories and mines, government agencies, and residential broadband; it can be widely used in Ethernet access scenarios such as small and medium-sized enterprises, Internet cafes, hotels, and schools.
1. Metropolitan area fiber broadband network: telecommunications, cable tv, network system integration, etc., according to network operators;
2. Broadband private network: suitable for financial, government, oil, railway, electric power, public security, transportation, education and other industries;
3. Multimedia transmission: integrated transmission of images, voice and data, suitable for remote teaching, conference tv, videophone and other applications;
