The DES-3810 Series 24 and 48-port switches are the atest additions to the D-Link xStack family of nextgeneration, high-end, multi-service Layer 3 switches. The DES-3810-28 provides 24 10/100 Mbps Fast Ethernet ports and 4 combo 1000Base-T/SFP Gigabit Ethernet ports. The DES-3810-52* provides 48 10/100 Mbps Fast Ethernet ports, 2 1000Base-T and 2 combo 1000Base-T/SFP Gigabit Ethernet ports. The Fast Ethernet ports allow users to connect to other LAN access switches. The combo ports provide users with a much higher level of flexibility for dedicated trunk connections between devices or core switches.
