2.5G Speed, Ready for Wi-Fi 6 and More
The DMS-1250 Series switches can enhance your network by connecting a Wi-Fi 6 Access Point to any of the 2.5 Gbps ports, effectively maximizing throughput and speed. Multi-Gigabit Ethernet eliminates potential bottlenecks with Wi-Fi 6 Access Points, enabling your network to fully leverage the efficiency and high speeds offered by Wi-Fi 6.

Cutting-Edge PoE Features Ensuring Reliable Power Delivery
PoE+ ports provide a high power budget to fulfill the most business needs. ​
The innovative PoE functions can ensure uninterrupted power delivery to the power devices.

Intelligent Fan Control with Quiet Operation
The DMS-1250 PoE models with built-in internal fans which can automatically work between 5 levels of cooling to prevent the device from overheating or manually set to OFF or Quiet mode according to environment or operation temperature.

6 kV Surge Protection for All Ethernet Ports
The DMS-1250 Series switches offer enhanced 6kV surge protection on all 2.5-Gigabit Ethernet access ports, ensuring that your network remains resilient and that your devices stay safe from electrical surges. ​​

Easy Management by DNC & D-View 8
The DMS-1250 Series switches​ offers a range of management tools to cater to users' diverse needs. D-Link Nuclias Controller (DNC) and D-Link Nuclias Hub (DNH) enable the discovery and management of multiple D-Link devices, providing access to configure settings efficiently. Furthermore, the DMS-1250 Series can be seamlessly managed through D-View 8, a comprehensive central network management system. SNMP functionality allows for centralized network asset management, remote configuration, and logging functions.

Best Choice for SOHO, SMB and MDU
The DMS-1250 Series switches​ are versatile, suitable for SOHO, SMB, and MDU environments. They provide high-speed data transmission with 2.5GE and a crucial 10G speed uplink for external connectivity. This high-speed uplink ensures that the entire MDU can access external services without encountering data bottlenecks. Furthermore, they effectively implement IEEE 802.3at or IEEE 802.3bt in DMS-1250-10SP, 10SPL, and 12TP to enable devices to connect and receive power supply. ​
