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.
![Example topology for multi-site network expansion.](/en/-/media/product-pages/dgs/1520/assets/dgs1520_06_zerotouch.png?h=640&w=597&la=en&hash=28C8EFB9A078B57FE9900E7A2472022C)
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.
*DGS-1520-28 and DGS-1520-52 only

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.
