The D-Link DGS-1520 series is the successor to the DGS-1510 switches.
There are four models in the family: DGS-1520-28, DGS-1520-28MP, DGS-1520-52 and DGS-1520-52MP.
The numerical part of the suffix indicates the number of ports, while the MP models feature power over Ethernet with a 370W budget (expandable to 740W with the optional DPS-700 unit).
The -28 provides 24 1000Base-T, two 10GBase-T and two SFP+ ports. The -28MP features 20 PoE 1000Base-T, four PoE 2.5GBase-T, two 10GBase-T and 2 SFP+ ports.
Similarly, the -52 has 48 1000Base-T, two 10GBase-T and 2 SFP+ ports, while the -52MP provides 44 PoE 1000Base-T, four PoE 2.5GBase-T, two 10GBase-T and 2 SFP+ ports.
This makes them the first of D-Link's smart managed switches to support 10G Base-T for uplink and stacking.
The multi-Gigabit PoE ports are a convenient way to connect 802.11ac/ax access points, the company observed.
Zero-touch provisioning means there is no need for on-site IT personnel to install the switches as part of multi-site network deployments.
The range is available immediately.
