PoE power supply switch refers to a switch that can provide network power supply to remote powered terminals through a network cable. It includes two functions: network switch and PoE power supply. It is a relatively common power supply device in PoE power supply systems. The port supports an output power of 15.4W, which conforms to According to the IEEE802.3af standard, the port supports an output power of 30W and conforms to the IEEE802.3at standard. It supplies power to standard POE terminal equipment through network cable power supply, eliminating the need for additional power wiring.
