For aggregating connections in enterprise networks, campus networks, and metropolitan area networks, the D-Link DGS-1530-28S/E managed Layer 2 switch has 24 1G SFP ports for downlink connections and 4 10G SFP+ ports for uplink connections. It supports physical stacking of up to 9 units via the 10G SFP+ ports, as well as Zero-Touch Provisioning (ZTP) for initial configuration.

Network features include VLAN, STP, LACP, IGMP/MLD snooping, QoS, and ERPS. The switch supports management via web interface, CLI, and SNMP, and has an RJ-45 console port and a USB port for firmware and backups.
