PoE switch 16-port + 4 combo ports RJ45/SFP Dahua PFS3218-16ET-135 The Dahua PFS3218-16ET-135 16-port PoE Switch + 4 RJ45/SFP combo ports is a cost-effective Layer 2 PoE switch that has been developed for IP surveillance systems. The PFS3218-16ET-135 is equipped with 16 RJ45 10/100Mbps ports with PoE 802.3af/at (power over ethernet) support and 2 RJ45 Uplink 1 Gbps shared (Combo) ports with 2 SFP insert ports. The total PoE power budget for connected devices is 135W. The device supports IEEE 802.3af, IEEE 802.3at and Hi-PoE standards (first 2 ports). The Dahua PFS3218-16ET-135 PoE switch is equipped with features such as PoE Watchdog, port isolation capability, QoS for VIP ports and support for long-distance 250m mode. It uses 16 PoE ports that allow the target device to be powered with a power consumption not exceeding 30W (the exception being the first 2 ports with Hi-PoE support, which can supply up to 60W). The switch uses intelligent PoE ports, which continuously regulate power consumption in the event of an overload. If all powered devices exceed 135W, the switch will automatically disconnect the lowest priority communication port. Features PFS3218-16ET-135:
