D-Link 28-Port 10GbE Multi-Gig Layer 3 Stackable Managed Ethernet Switch (DXS-3130-28) 24-Port 10GE Ports, 4×25GbE SFP28 Uplinks, 9-Unit/200Gbps Stacking, Surge Protection, Rack-Mountable, Follows NDAA/TAA, Lifetime Warranty

All Ports. All Power. All Performance.
Built for High-Density Access and Aggregation

• 24 10GbE Multi-Gig on Every Port: * All 24 ports support 1G/2.5G/5G/10GbE for modern Wi-Fi AP backhaul, workstations, servers, and IoT aggregation.
• 4× 25GbE SFP28 Uplinks Built In: Provides the bandwidth to help prevent uplink bottlenecks in high-density deployments, connect stacks without congestion, and link smoothly into aggregation or core, no costly add-on modules.
• Stackable Growth: Up to 9 units with 200 Gbps* stack bandwidth, managed as one for simpler multi-closet builds.
• Layer-3 Routing for Campus/Aggregation: Static, RIP, and OSPF with VRRP/ECMP improve default-gateway resilience and steer traffic efficiently.
• High-Availability Recovery: ERPS (~50 ms), STP/RSTP/MSTP, and Link Aggregation help speed failover and maintain uptime
• Enterprise-Enhanced Features: 6 kV surge protection* and Optional Redundant Power Supply (RPS) support (DPS-500A) help provide protected power and service continuity
• Smart 5-Speed Fan Cooling: Variable fan speeds help keep noise low in typical use while maintaining safe operating temps
• Multicast and QoS at Scale: IGMP/MLD and PIM-SM with 8 queues per port help stabilize video streams and voice
• Versatile Management Options: Web-based GUI, CLI, SNMP/sFlow, dual image/config, DHCP auto-config; optional Nuclias Hyper (license included, no subscription fee) or Nuclias Controller (sold separately) for centralized control of access points and switches
• Access Control & Policy Enforcement: 802.1X, MAC/Web authentication, ACLs, DHCP Snooping, and IP-MAC-Port Binding help reduce spoofing and keep unauthorized devices off the network
• Energy-Efficient Design: IEEE 802.3az (EEE), auto power-down on idle links, cable-length optimization, and smart variable-speed fans help reduce consumption during low-traffic periods.
  
• NDAA/TAA: Follows NDAA/TAA sourcing standards for public sector and enterprise projects
• Trusted Business-Class Reliability: Backed by D-Link’s Lifetime Warranty (North America) and over 39 years of networking experience
