ZyXEL Dimension ES-3124PWR is an intelligent L2+ managed Power over Ethernet (PoE) switch designed for enterprises and campuses need to deploy powered networking devices on remote locations. The ES-3124PWR conforms to IEEE 802.3af standard supporting all the different kinds of PoE network infrastructures in the corporate. The PoE technology adopted by ES-3124PWR allows enterprises to transmit both data and electrical power to remote powered devices, such as IP camera, IP phone, and wireless AP or routers through existing CAT-5 UTP cabling. This provides several advantages like single cabling, centralized remote power monitoring, as well as plug-and-play convenience and flexibility. These advantages will result in to lower deployment cost, higher management efficiency, and future reconfiguration flexibility. With twenty-four 10/100Mbps RJ-45 ports, two GbE copper ports and two dual-personality SFP / copper GbE interface, ZyXEL ES-3124PWR boasts a high performance switch architecture that is capable of providing non-blocking switch fabric and wire-speed throughput as high as 12.8Gbps. Its four built-in GbE uplink ports offer incredible extensibility, flexibility, and connectivity to the Core switch or Servers. ZyXEL ES-3124PWR adds a built-in DC power receptacle on its rear panel for external Backup Power System connection for even higher reliability; and the system can switch to the alternative power source automatically in response to different situations. ZyXEL ES-3124PWR is loaded with powerful traffic management and QoS features. For instance, the ES-3124PWR provides 8 priority queues per port for different types of traffics, allowing administrators to set policies for class based filtering and rule-based rate limitation. The ES-3124PWR prioritizes applications with WFQ (Weighted Fair Queuing) scheduling algorithm allocating appropriate bandwidth to important voice and video applications and empowering the enterprise to take full advantage of the limited ne
