Spesification Network Switch DMS-1250-28P
Next-Gen Multi-Gigabit PoE++ Switch for Enterprise Networks

The D-Link DMS-1250-28P is engineered to meet the demands of modern enterprise networks, offering 28 x 2.5G PoE++ access ports and 4 x 10G SFP+ uplinks for seamless connectivity. With support for IEEE 802.3af/at/bt PoE standards, it delivers up to 90W per port and a total PoE budget of 475W, making it ideal for powering Wi-Fi 6/7 access points, PTZ cameras, digital signage, and IoT devices.

Multi-Gigabit Ethernet ensures high-speed backhaul without re-cabling, while built-in 6kV surge protection safeguards against electrical spikes. Advanced Layer 3 Lite features such as VLAN segmentation, static routing, ERPS, QoS, IGMP snooping, and redundancy enhance performance and reliability across enterprise and campus environments.

Administrators benefit from centralized management via Web UI, CLI, SNMP, Nuclias Controller, and D-View 8, with real-time monitoring and visual dashboards. Smart cooling with five-speed fans optimizes airflow and noise, ensuring stable operation in busy networks. With TAA/NDAA compliance, robust security (802.1X, ACLs, DHCP snooping, IP-MAC binding, Safeguard Engine™), and a lifetime warranty, the DMS-1250-28P is a future-proof investment for schools, offices, retail, and government deployments.
