• D-Link DGS-1520-28MP Layer 3 Stackable Smart Managed Switches
  

  Smart Managed Switches, Redefined
  High-performance stackable switches with 10 Gigabit connectivity allow businesses to maximise productivity and uptime with a highly expandable and resilient network.

  Connect up to eight switches to create a redundant stack with up to 384 Gigabit ports

  High capacity data transfer between connected devices with up to 188 Gbps

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

  High Availability
  Boost your network performance and reliability while simplifying management and cabling. Physically stack up to 8 switches with a total of 80G stacking bandwidth.

  Stacking Bandwidth
  2 x 10GBase-T + 2 x SFP+ ports for stacking and connection to the network core
  Physically stack up to 8 switches with a total of 80G stacking bandwidth.

  Designed for Wi-Fi 6
  Multi-Gigabit 2.5G ports on the DGS-1520 Series PoE switches eliminate potential bottlenecks when connecting to Wi-Fi 6 access points capable of Gigabit+ wireless speeds.

  Zero-Touch Provisioning
  For multi-site network expansion, the latest firmware and network configurations can be downloaded onto the DGS-1520 Series switches without the need for on-site IT personnel, for rapid and effortless deployment.

  Advanced L2 and L3 Functionalities
  Advanced software features such as selective Q-in-Q, VRRP, RIP and OSPF allows businesses to adapt to changes in their network. For those with expanding network requirements and bandwidth demands, the DGS-1520 Series is a highly cost-effective upgrade option to add 10 Gigabit connectivity to the network infrastructure.

  Guarantee Uptime with Power Redundancy
  For a truly resilient network, connect up to four DGS-1520 switches* to the optional redundant power supply (DPS-520). Should the internal power supply unexpectedly fail on any of the connected switches, your network will be unaffected, allowing the business to continue as usual.

  Flexible Hybrid Stacking
  Stack up to eight DGS-1520 switches using both copper 10GBASE-T and/or fibre SFP+ ports. The hybrid stacking support adds flexibility as well as lowering the cost of cabling by using copper instead of all fibre.

  Application Scenario
  See how DGS-1520 Series switches can help businesses create a reliable and high-performance network.

  Simplified Management
  Managed multiple large wired/wireless device networks with D-View 7 for centralised management to reduce costs and maintenance. D-Link Network Assistant (DNA) is also available to easily set up and manage smaller networks.
