DGS-3420-52P D-Link 81W 48-Port 176Gbps 10/100/1000Base-T Managed Stackable Gigabit Ethernet Switch with 4 10-Gigabit SFP+ Ports Rack Mountable Network Switch

D-Link 81W DGS-3420-52P

Built for enterprise access layers, branch offices and wiring closets that connect hundreds of users and devices, the D-Link 81W (DGS-3420-52P) is a 48-port managed Gigabit Ethernet switch from D-Link, part of the D-Link managed series.

It offers 48 ports of Gigabit Ethernet, enough to connect workstations, servers, phones, access points and other network devices. 10 Gigabit Ethernet capability provides high-bandwidth links to servers, storage or the network core, which helps prevent bottlenecks. Modular optical slots give you flexible fiber uplinks for longer distances and electrical isolation. Bringing many connections onto one high-density switch simplifies patching, labeling and troubleshooting in the wiring closet. A wired connection delivers steadier speeds and lower latency than Wi-Fi for fixed devices. High port density reduces the number of switches you need in each rack, which saves space, power and management effort.

Full management capabilities let your IT team tune performance, enforce policies and monitor every port. Stacking support lets you manage multiple units as one logical switch as your port count grows. QoS policies keep calls and video meetings clear, even during heavy file transfers. Switches like this form the backbone of everyday network communication, linking users to applications, storage and the internet. Aggregated links provide extra uplink capacity and keep traffic flowing if one cable fails. SNMP monitoring and port statistics help IT teams spot problems before users notice them.

Physically, it uses a rack-mountable format for a clean, organized installation. The DGS-3420-52P creates a tidy, central hub for all wired devices in the area it serves. Match the part number DGS-3420-52P against your existing equipment for a seamless replacement or expansion. Choose the D-Link DGS-3420-52P when you need D-Link managed Gigabit Ethernet switching you can rely on.
