The xStack DGS-3420 series of next generation Layer 2+ Gigabit switches delivers performance, flexibility, security, multi-layer QoS, and accessibility, along with redundant power solutions for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP, 10-Gigabit SFP+ support, and advanced software solutions, these switches can act as either departmental access layer devices or aggregation switches to form a multilevel network structured with backbone and centralized high-speed servers.
Easily deployed and simple to manage, the DGS-3420 can be stacked with any switch that supports D-Link's single IP management to form a multi-level network structured with backbone and centralized high-speed servers.
Redundant ring stacking
Alternatively, depending on whether linear or fault tolerant ring stacking is implemented, users can use one or two 10-Gigabit SFP+ ports to create a physical stack.
Security, performance and availability
The DGS-3420 series provides a complete set of security features including L2/L3/L4 multi-layer Access Control Lists and 802.1X user authentication via TACACS+ and RADIUS servers. The DGS-3420 series offers extensive VLAN support including GVRP and 802.1Q VLAN to enhance security and performance.
The DGS-3420 series also features comprehensive IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6, RIPng, and more. With 10-Gigabit connectivity and IPv6 support, the series enables you to future-proof your network for cost efficiency and longevity while meeting the requirements that future IPv6 capable network devices require.
D-Link Green technology
D-Link is striving to take the lead in developing innovative and power-saving technology that does not sacrifice operational performance or functionality. The DGS-3420 series implements D-Link Green technology, which includes power saving through link status, smart fan design, increased heat dissipation, and cable length detection.
