D-Link Ethernet Switch Gigabit

The DMS-3130 series offers two 10GBASE-T ports, four SFP28 ports with 10/25 Gbit/s, and a switching capacity of up to 400 Gbit/s. With physical stacking of up to 9 switches and comprehensive Layer 2 and Layer 3 features, it is ideal for metro Ethernet installations. Advanced L2 and L3 features such as port security, storm control, link aggregation, and spanning tree protocols are also included. Management options such as 802.3ah OAM, 802.1ag CFM, and industry-standard CLI, as well as support for multiple images and configurations, are provided. There are 4 SFP28 uplink ports with 25 Gbit/s, physical stacking for redundancy, and integrated G.8032 Ethernet Ring Protection Switching (ERPS), which minimizes recovery time to 50 ms. A USB 2.0 interface allows for the storage of configuration files, boot images, and system logs. Additionally, all models support an external redundant power supply to ensure maximum availability. The DMS-3130-30PS supports PoE PD on the MGMT port and can be powered by a PoE switch.
