Unparalleled Flexibility Easily deployed & simple to manage, the DGS-3420 can be virtually stacked with any switch that supports D-Link′s Single IP Management (SIM) to form a multi-level network structured with backbone & centralised high-speed servers. The virtual stack can include units located anywhere on the same network domain, eliminating cable distance barriers, limitations of physical stacking, & the need for stack cabling. 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 1. Switches in the stack are hot-swappable to minimise network downtime in case a replacement is required, eliminating single points of failure. Up to 12 units or 576 Gigabit ports can be configured for a stack using direct attached cables** allowing high bandwidth & high port densities on the already cost efficient DGS-3420 Series. Security, Performance & Availability The DGS-3420 Series provides a complete set of security features including L2/L3/L4 multi-layer Access Control Lists & 802.1x user authentication via TACACS+ & RADIUS servers. The DGS-3420 Series offers extensive VLAN support including GVRP & 802.1Q VLAN to enhance security & performance. A robust set of L2/L3/L4 Qo S/ Co S solutions help ensure that critical network services such as Vo IP, ERP, Intranet, & video conferencing are served with proper priority. The DGS-3420 Series provides D-Link′s Safeguard Engine to increase the switch′s reliability, serviceability, & availability to prevent malicious flooding traffic caused by worms or virus infections. Bandwidth Control can be flexibly set for each port using pre-defined thresholds to assure a committed level of service for end users. For advanced applications, flow-based bandwidth control allows easy fine tuning of service types based on specific IP addresses or protocols. IPv 6 Technology The DGS-3420 Series also features comprehensive IPv 6 support, including IPv 6 Tunnelling, ICMPv 6, DHCPv 6, RIPng, etc. With 10-Gigabit connectivity & IPv 6 support, the DGS-3420 Series enables you to future-proof your network for cost efficiency & longevity while meeting the requirements for IPv 6 capable network devices in the coming years. D-Link Green Technology D-Link is striving to take the lead in developing innovative & power-saving technology that does not sacrifice operational performance or functionality. The DGS-3420 Series implements the D-Link Green Technology, which
Includes:: a power saving mode, smart fan, reduced heat dissipation, & cable length detection. The power saving feature automatically powers down ports that have no active link. The Smart Fan feature allows for the built-in fans to automatically turn on at a certain temperature, providing continuous, reliable & eco-friendly operation of the switch. The Time Based Po E feature allows to create a schedule when the Po E delivery can be disabled & save more energy. Features
