[24-Port Gigabit PoE Switch with 156W Power]This unmanaged PoE switch features 24 PoE+ 10/100/1000 Mbps RJ45 ports and 2 SFP uplink ports, delivering up to 30W per port with a total PoE power budget of 156W. [Plug-and-Play Ethernet Power]Compliant with IEEE 802.3af/at PoE standards, this switch automatically detects and powers PoE devices. Non-PoE devices require separate power sources. [Intelligent Protection]Equipped with professional PoE chips, the switch intelligently detects data exchange between PoE ports and devices, automatically restarting when anomalies are detected without affecting other ports. [4KV Lightning Protection]Features professional 4KV lightning surge protection to safeguard the switch and connected devices from sudden surges and lightning strikes. [Extended Transmission Range]Automatically detects and adjusts transmission rates, extending PoE range up to 250 meters (820 feet) at 10 Mbps. For optimal long-distance performance, use Cat5e or higher cables. [Energy-Efficient Design]Supports IEEE 802.3X flow control and IEEE802.3az energy-efficient Ethernet for stable, reliable, and efficient data transmission. [Versatile Application]Features a durable metal casing and fanless design for quiet operation. Ideal for PoE IP cameras, wireless access points, IP phones, and computer networking equipment.
