Perfect for Modern Wi-Fi 6/6E Deployments
The DMS-1250-18P eliminates the performance bottleneck that occurs when Wi-Fi 6 or Wi-Fi 6E access points are connected to standard 1G switches. With 2.5 Gbps ports optimized for next-generation wireless, your network can fully leverage the efficiency and throughput of modern access points, ensuring seamless 4K video streaming, large file transfers, and lag-free cloud application performance across offices, schools, hotels, and retail environments.
Enterprise-Grade Power & Perpetual PoE
With support for the latest IEEE 802.3bt PoE++ standard, the DMS-1250-18P delivers up to 90 watts per port to power demanding devices such as high-power Wi-Fi 6E APs, outdoor PTZ cameras, video phones, and interactive displays. The switch also features Perpetual PoE technology, which maintains power to connected devices even during switch reboots or firmware upgrades, ensuring zero downtime for mission-critical systems like surveillance and access control.
Centralized Management & Control
Manage single or multiple DMS-1250-18P switches with ease using D-Link Nuclias Network Controller for cloud-based centralized management, or via traditional methods including Web UI, CLI, SNMP, and D-View 8. Features like real-time monitoring, device discovery, bulk configuration, and remote firmware updates simplify deployment and ongoing administration for IT teams managing distributed networks.
Robust Security & Reliability
The DMS-1250-18P includes comprehensive security features such as 802.1X authentication, RADIUS/TACACS+ AAA support, ACLs (Access Control Lists), DHCP snooping, IP-MAC binding, and D-Link Safeguard Engine for real-time protection against malicious traffic and DDoS attacks. Combined with ERPS (Ethernet Ring Protection Switching) for sub-50ms failover and dual firmware images, this switch ensures maximum uptime and network resilience.
Smart Cooling & Energy Efficiency
The DMS-1250-18P features a 5-speed intelligent fan system that automatically adjusts cooling based on operating temperature and PoE load. Administrators can manually configure fan modes via Web UI or CLI to balance performance and acoustics. The switch also supports IEEE 802.3az Energy Efficient Ethernet (EEE) to reduce power consumption during periods of low network activity, lowering operational costs without sacrificing performance.
