The DGS-3000 Series Managed Gigabit Switches from D-Link are designed for Metro Ethernet and campus networks, offering a range of ports, including 10/100/1000BASE-T, 1G SFP, and 10G SFP+ for high bandwidth. Key features include surge protection, Power over Ethernet (PoE) support (on select models), and Ethernet Ring Protection Switching (ERPS) for fast failover and minimal downtime. The switches also support Link Aggregation for redundancy and load balancing. With multilayer QoS/CoS for prioritizing critical traffic like VoIP and video, advanced security with 802.1X authentication, and flexible network policies, the DGS-3000 Series ensures efficient, secure, and resilient networking. Easy to manage with Single IP Management (SIM), web-based interfaces, and industry-standard protocols like SNMP and SSL, it’s a reliable solution for scalable enterprise networks.
