x4

Four 2.5G PoE ports (PoE models), ideal for Wi-Fi 6 access points.

High availability

Simplification of management and cabling increases the efficiency and reliability of the network. Physical stacking up to 8 switches with a total bandwidth of 80G.

Designed with Wi-Fi 6 in mind

The multi-gigabit 2.5G ports on the DGS-1520 series PoE switches eliminate potential bottlenecks in connecting to WiFi 6 gigabit access points.

Touchless deployments

For multi-site network expansion, the latest firmware and network configurations for the DGS-1520 series switches can be downloaded without the need to involve on-site IT personnel, making deployments easier and faster.

Advanced L2 and L3 features

Advanced, selected software features – Q-in-Q, VRRP, RIP and OSPF enable adaptation to changes in the network. For businesses with increasing bandwidth and network expansion requirements, the DGS-1520 series switches are a cost-effective upgrade option with 10-gigabit connections for network infrastructure.

Hybrid staking

Stack up to eight DGS-1520 switches using 10GBASE-T copper and/or SFP+ fiber ports. Hybrid stacking support increases cabling capability and lower cost by using copper instead of fiber.

Simplified management

Centrally manage multiple large networks with wired or wireless devices using D-View 7 to reduce cost and maintenance. There is also a D-Link Network Assistant (DNA) available to simplify setup and management of smaller networks.
