D-Link DGS-1530-28S/E - Smart Managed Fiber Switch, Black

The D-Link DGS-1530-28S/E is a Layer 2, non-PoE network switch designed for fiber-based enterprise access and edge deployments. It features 28 SFP slots, configured as 24 Gigabit downlinks and four 10G SFP+ uplink ports. This configuration provides a total switching capacity of 128 Gbit/s, enabling high-traffic throughput across connected nodes. By using fiber connections instead of standard RJ-45 copper ports, the unit facilitates long-distance data transmission across large campus or office environments.

The rack-mountable chassis fits standard server racks and offers multiple management and security features. Administrators can configure network settings via a web interface or the RJ-45 console port for command-line access. Network traffic and security are managed through integrated Layer 2 functions, including Access Control Lists (ACLs), ARP inspection, and MAC address filtering. Quality of Service (QoS) protocols prioritize essential data streams over standard network traffic. A USB 2.0 port is included for local configuration backups and firmware updates.
