???4 Port Gigabit PoE Switch@65W???Unmanaged 5 port PoE switch with 4 PoE+ 10/100/1000 Mbps RJ45 port and 1 gigabit Ethernet Uplink port, 4 PoE+ ports providing up to 30W per port, total PoE power budget 65W(external power supply included) ???Power over Ethernet, Plug and Play???Compliant with IEEE 802.3af/at PoE standard, this unmanaged poe switch 4 port can automatically detect and identify PD devices and provide them with power and data. The small gigabit PoE+ switch can only transmit data and cannot power non-poe devices, so the connected non-poe device needs to be powered separately. Plug and play, easy setup with no software configuration required. ???Short-circuit Protection???Equipped with professional poe chip, the PoE network switch can intelligently detect the data exchange between the poe port and the terminal device. When an abnormality is detected, it will automatically restart and return to normal without affecting other ports, reducing maintenance costs. ???4KV Lightning Protection???PoE switch features professional 4K lightning surge protection, which helps prevent sudden surges and lightning strikes from damaging poe switch and connected equipment. ???250 Meters Extend Transmission???Automatically detect the transmission distance and adjust the transmission rate, extend up to 250m(820ft) data and power PoE transmission range (Speed will drop to 10 Mbps). For better results over long distances transmission, use cat5e cables or above. ???Energy saving design compliant with IEEE802.3az???Support IEEE 802.3X flow control, ensuring stable, reliable, and efficient data transmission. ???Fanless Design, Wide Application???Durable metal housing with low power consumption fanless design to ensure quiet operation. PoE gigabit switch is widely used in scenarios such as PoE IP cameras, wireless access points, IP phones and computer network devices, etc. ???After-sales Service???All products are rigorously tested before shipment. We provide one-year warranty for the whole product and lifetime technical support. The message will be answered within 24 hours.
