D-LINK DGS-1250-52X 48-PORT GB, 4X 10G SFP +

D-LINK DGS-1250-52X 48-PORT GB, 4X 10G SFP +

The DGS ‑ 1250 is an affordable switch that can be deployed as master switches in midsize companies and as access switches in large corporations. Their advantages include high port density, ports with high capacity, which avoid the so-called bottlenecks, large PoE budget, useful for larger deployments, redundancy to reduce downtime, easy-to-use graphical user interface, dedicated console and full control via CLI.
