DGS-3420-28SC D-Link 20-Port 128Gb/s 10-Gigabit SFP+ Rack Mountable Gigabit Ethernet Network Switch

D-Link DGS-3420-28SC

Upgrade your network with the D-Link DGS-3420-28SC, a 20-port Gigabit Ethernet switch designed for enterprise edge deployments where security policies, VLAN segmentation and uptime are essential.

Its 20-port design with Gigabit Ethernet connectivity consolidates many connections onto one device. 10 Gigabit Ethernet capability provides high-bandwidth links to servers, storage or the network core, which helps prevent bottlenecks. Pluggable fiber slots let you choose the right transceiver for short- or long-distance links between buildings or racks. Gigabit connections give every user enough bandwidth for cloud applications, large files and HD video. Stable switching is the foundation for every application your users rely on. Check that your chosen SFP-type transceivers or DAC cables are compatible with the switch before ordering optics. Optical links resist electrical noise and reach far beyond copper limits, which is useful between buildings. A moderate number of ports balances capacity and cost for small teams and branch sites.

Its rack-mountable form factor fits neatly into equipment rooms, cabinets or workspaces. Typical locations include wiring closets serving offices, classrooms and clinical areas. Mount it where air can circulate freely to support long service life. Standardizing on one switching platform makes configuration templates, training and spares easier to manage. A UPS on the network rack keeps connections alive through short power outages. Match the part number DGS-3420-28SC against your existing equipment for a seamless replacement or expansion. A dedicated switch gives your network a central, organized connection point for wired devices. For anyone sourcing D-Link Gigabit Ethernet switching, the DGS-3420-28SC combines D-Link engineering with practical, everyday performance.
