| Marketing description |
| The DGS-1520 series, a new generation of Lite Layer 3 Stackable Smart Managed Switches, includes four 10 GB ports for uplink or stacking up to eight switches in total, with an 80-gigabit stacking throughput. Designed for seamless deployment of networks across multiple sites with Zero Touch Provisioning, the DGS-1520 series is also powerful enough for server and storage applications. |
| Product features |
-
High availability
The DGS-1520 series provides reliable yet affordable gigabit connectivity with four 10-gigabit ports (two 10G Base-T and two 10G SFP) for high-speed uplink or stacking. Boost your network performance, simplify your network infrastructure, improve throughput and reduce cabling complexity.
-
Zero Touch Provisioning
Zero-touch provisioning is ideal for expanding networks across multiple sites. Simply pre-configure your network settings in a central location, then install the DGS-1520 switches for effortless deployment.
-
Powerful stacking capability
Stack up to eight DGS-1520 switches with a total throughput of 80 GB when stacked, using hybrid mode (copper and/or optical fiber), increasing flexibility, scalability and cost-efficiency for small and medium-sized businesses.
