Usage Tips: 1. Complies with IEEE 802.3af Power over Ethernet (1000M supported) and extends the range of PoE by an additional 100 meters. 2. Automatically detects and protects PoE equipment from damage due to incorrect installation. 3. Plug-and-play; no configuration required. 4. 4-Port PoE extender can forward both Ethernet data and PoE power to one terminal device via Cat5, Cat5e, Cat6, or UTP cables. 5. The 4-Port PoE Extender features 3 x 10/100M LAN ports, with one port for power input and three ports for power output. Complies with 10/100BASE-TX and IEEE 802.3af PoE standards. Ideal for use with access points, IP cameras, IP phones, and other network devices in locations lacking power outlets or located far from power sources. Suitable for installation in hotels, schools, buildings, and villages.
