The DMS-1250-28P is a 28-port Layer 2 Smart PoE switch designed for growing businesses that need high-speed connectivity, robust PoE power, and centralized management. Built by D-LINK SYSTEMS, it combines enterprise-grade reliability with streamlined control for scalable networks.
-
24 x 2.5G PoE Ports: Downlink PoE connectivity for cameras, phones, and access points directly from the switch.
-
4 x 10G SFP+ Uplinks: High-speed fiber uplinks for fast aggregation to core switches or data centers.
-
475W Total PoE Budget: Ample power to support a diverse mix of PoE devices without external injectors.
-
6kV Surge Protection: Built-in protection on all 2.5G ports to safeguard connected hardware.
-
LACP 802.3ad: Link Aggregation for increased throughput and redundancy across connections.
-
Static Routing: Efficient inter-VLAN routing to optimize East-West traffic without extra routing hardware.
-
Loopback Detection: Proactively prevents network loops and minimizes downtime.
-
STP/RSTP/MSTP: Advanced spanning tree protocols for scalable, loop-free network topologies.
-
AAA Support (RADIUS/TACACS+): Centralized authentication to strengthen access control and security policies.
-
D-Link Safeguard Engine: Integrated security features to mitigate malware and network threats at the edge.
-
Nuclias Network Controller Compatibility: Centralized, efficient management and provisioning across multiple sites.
-
Enterprise-Grade Management: Robust, scalable administration designed for growing networks and IT teams.
The DMS-1250-28P is engineered to simplify growth without compromising security or performance. Power-hungry devices such as IP cameras and VoIP phones can be deployed more freely thanks to the broad PoE budget, while 2.5G performance keeps bandwidth-intensive applications responsive. With LACP, STP variants, and loop-detection, networks stay resilient under load or during topology changes. Centralized security and management—via RADIUS/TACACS+ and Nuclias—mean IT teams can enforce policy consistently and scale operations as the network expands.
