This D-link DGS-1210-28P is part of D-Link\'s 3rd generation of Web Smart Switches that integrates advanced management and security functions for performance and scalability. With D-link Green technology now in its second generation, this D-Link DGS-1210-28P provides a complete, affordable and eco-friendly solution for small and medium businesses (SMB). **Power over Ethernet (PoE) support** This D-Link DGS-1210-28P features 24 PoE ports. They provide either up to 30W on 4 ports, 15.4W on 12 ports or 7.5W on 24 ports. This gives administrators the flexibility to connect 802.3af compliant devices such as network cameras and IP phones, as well as 802.3at pre-standard equipment such as 802.11n Access Points. Uniquely, the PoE function is programmable, so power can be cut at certain times to save energy. **Seamless Integration** This D-Link DGS-1210-28P includes 24 10/100/1000 Mbps ports capable of connecting to existing Cat.5 twisted-pair cables and the last four ports of this D-Link DGS-1210-28P combine SFP and copper connectivity into one port to provide a flexible solution for server connections via fiber interface. Using the default presets, the administrator can quickly set up the switch without worrying about reconfiguring any settings and providing easy access for the user. **Extensive Layer 2 Features** Equipped with a complete lineup of L2 features, these switches include IGMP Snooping, Port Mirroring, Spanning Tree and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to this D-Link DGS-1210-28P switch for fast, reliable data transfer. At 2000 Mbps Full Duplex, the Gigabit ports provide high-speed data pipes to servers with minimum data transfer loss. Network maintenance features include Loopback Detection and Cable Diagnostics. Loopback Detection is used to detect loops created by a specific port and automatically shut down the affected port. Cable Diagnostics is desig
