xStack L2+ Managed Stackable Gigabit Switch
The DGS-3420 Series xStack L2+ Managed Stackable Gigabit Switches are next generation switches that deliver 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.
– 48x 10/100/1000BASE-T PoE ports
– 4x SFP+ ports
– 130.95 Mpps Packet Forwarding Rate
– 176 Gbps Switch Fabric
– 802.3af and 802.3at Power Over Ethernet support
Support for Duplex Chain/Ring topology for up to 12 physically stacked units as well as virtual stacking managed via a single IP provides flexibility and convenience.
Innovative Safeguard Engine, ACL, and ARP Spoofing Prevention protect your network from malicious attacks and unauthorized access.
A suite of D-Link Green Technology features help save energy automatically and reduce costs, without sacrificing performance.
Easily deployed and simple to manage, the DGS-3420 Series switches 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. The virtual stack can include units located anywhere on the same network domain, and uses optional 10-Gigabit uplinks to move intra- stack traffic at 20 Gbps full duplex speeds.
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. The power-saving feature automatically powers down ports that have no link or link partner. The Smart Fan design allows the built-in fans to automatically turn on only at a certain temperature, providing continuous, reliable, and eco-friendly operation.
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. 12 units or 576 Gigabit ports can be configured for a stack using directly attached cables to provide high bandwidth on the DGS-3420 Series with cost efficiency. Support for virtual stacking provides further convenience by allowing centralized management of ports across different locations for simplifying large-scale deployments.
The DGS-3420 Series also features comprehensive IPv6 support, including IPv6 Tunnel, ICMPv6, DHCPv6, RIPng, IPv4/IPv6 dual stack, and more. With 10-Gigabit connectivity and IPv6 support, the series enables you to futureproof your network for cost efficiency and longevity while meeting the requirements of IPv6-capable network devices.
Security, Performance & 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. A robust set of L2/L3/L4 QoS/CoS solutions help ensure that critical network services such as VoIP, ERP, Intranet, and video conferencing are served with proper priority. The series also provides D-Link’s Safeguard Engine to increase reliability, serviceability, and availability by preventing malicious flooding of traffic caused by worms or virus infections.
