Built for High-Density and Aggregation 

• 24 10GbE Multi-Gig PoE++ on Every Port: All 24 ports support 1G/2.5G/5G/10GbE* for modern Wi-Fi access points, PTZ cameras, kiosks, and signage
• Integrated 4x25GbE SFP28 Uplinks: Offers the required bandwidth
  to connect stacks without congestion, avoid uplink bottlenecks in high-density deployments, and facilitate a seamless transition into aggregation or core networks with no expensive add-on modules.
• Scalable: PoE++ (up to 60 W*), high PoE budget Standard power output is 790 W*, but it can be increased to 1440 W* with a hot-swappable redundant PSU (available separately).
• Campus/Aggregation Layer-3 Routing: Static, RIP/RIPng, and OSPFv2/v3 with VRRP and ECMP enhance default-gateway resilience and effectively direct traffic.
• High-Availability Recovery: Link Aggregation, STP/RSTP/MSTP, and ERPS (~50 ms) speed up failover and support uptime across links and rings.
• Enterprise-enhanced features include a hot-swappable PSU option (DXS-PWR1200AC), perpetual/fast PoE, and 6 kV surge protection. Ensures service continuity and protected power.
• Multicast and QoS at Scale: PIM-SM with eight queues per port and IGMP/MLD help stabilize voice and video streams.
• Access Control & Policy Enforcement: IP-MAC-Port Binding, MAC/Web authentication, ACLs, DHCP Snooping, and 802.1X all help prevent spoofing and keep unauthorized devices off the network.
• Stackable Growth: For multi-closet deployments, up to nine units with a 200 Gbps* stack bandwidth can be managed as a single unit.
• Web-based GUI, CLI, SNMP/sFlow, dual image/config, DHCP auto-config, and optional Nuclias Hyper (license included, no subscription fee) or Nuclias Controller (separately sold) for centralized control of switches and access points are examples of versatile management options.
• Energy-Efficient Design: Smart variable-speed fans, cable length optimization, IEEE 802.3az (EEE), auto power-down on idle links, and optional PoE scheduling all contribute to reducing power consumption after hours.
• Smart 5-Speed Fan Cooling: During normal operation, variable fan speeds help maintain safe operating temperatures while reducing noise.
• NDAA/TAA: Adheres to NDAA/TAA sourcing guidelines for enterprise and public sector projects.
• Reputable Business-Class Dependability: Supported by more than 39 years of networking experience and D-Link's Limited Lifetime Warranty (North America).
