D-Link xStack 24-port 10/100/1000 Layer 2+ Stackable Managed Gigabit Switch including 4-port Combo 1000BaseT/SFP plus 4 10GE SFP+

The DGS-3420 Series of next generation Layer 2+ Gigabit switches delivers performance, flexibility, security, multi-layer QoS and access control, along with redundant power solutions for SMBs and enterprises. With high Gigabit port densities, Gigabit SFP and 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. Service providers can take advantage of the high SFP density switches to structure the aggregation of Fibre to the Building (FTTB) networks that they extend to the subscriber's sites. Easily deployed and 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 and centralized high-speed servers. The virtual stack can include units located anywhere on the same network domain, eliminating cable distance barriers, limitations of physical stacking, and the need for stack cabling. 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. Switches in the stack are hot-swappable to minimize 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 and high port densities on the already cost efficient DGS-3420 Series. 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 DGS-3420 Series provides D-Link's Safeguard Engine to increase the switch's reliability, serviceability, and 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. The DGS-3420 Series also features comprehensive IPv6 support, including IPv6 Tunneling, ICMPv6, DHCPv6, RIPng, etc. With 10-Gigabit connectivity and IPv6 support, the DGS-3420 Series enables you to future-proof your network for cost efficiency and longevity while meeting the requirements for IPv6 capable network devices in the coming years. 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 the D-Link Green Technology, which includes a power saving mode, smart fan, reduced heat dissipation, and 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 and eco-friendly operation of the switch.

The short answer is, you probably are! Our credit provider carries out credit checks and has a few requirements for offering finance but please make sure you meet these simple requirements

  • Your order is £99 or more
  • You are 18 years or older
  • You are a UK resident, and have been for more than 3 years

What if I am declined for finance?

When you're applying for finance you always need to remember that there is a possibility you will be declined. This can often be caused by one of a number of reasons, but usually it will be caused by a negative credit score or a default on an existing loan. We've done our best to make it as easy as possible for our customers that aren't successful in applying to continue their order and pay by Credit Card, Debit Card, PayPal Wallet or Bank Transfer - it really is as simple as clicking "complete my order using a different method".
