D-Link DGS-1520-52MP 44-Port Smart Managed Switch

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 a total of eight switches with a total of 80 Gigabit stacking bandwidth. Designed for effortless multi-site network deployments with Zero Touch Provisioning, the DGS-1520 Series is also powerful enough for server and storage applications. For unrestricted Wi-Fi 6 edge device capabilities, PoE models offer four 2.5 GB Base-T ports for Multi-Gigabit connectivity. For SMBs with expanding networks and significant bandwidth growth, the DGS-1520 effortlessly adds highly cost-effective 10 GB connectivity to ensure seamless aggregation between access and core layers.

High Availability:
The DGS-1520 Series brings 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 bandwidth and reduce cabling complexity.

Zero Touch Provisioning:
Zero Touch provisioning is perfect for multi-site network expansions. Simply preconfigure your network settings in a centralized location, then install the DGS-1520 switches for effortless deployments.

Multi-Gigabit Support:
Multi-Gigabit ports on the DGS-1520 Series switch (PoE models only) support 100 MB / 1 GB / 2.5 GB speeds to maximize various device capabilities, such as Wi-Fi 6 (802.11ax) access points, which can often exceed single Gigabit speeds.

Powerful Stacking Capability:
Stack up to eight DGS-1520 switches with a total of 80 GB stacking bandwidth using hybrid mode (copper and/or fiber), increasing flexibility, scalability, and cost effectiveness for SMBs.

Low Network Latency, High PoE Budget:
High Gigabit-port density with up to 188 GB total switching capacity, and up to 30 W per port with 370 W total PoE budget to power your PoE-enabled devices.
