Enterprise-Grade Power over Ethernet
The DGS-3130-30PS features 24 PoE+ ports supporting IEEE 802.3af and IEEE 802.3at standards, providing up to 30W per port. With a default power budget of 370W (expandable to 740W), you can power IP surveillance cameras, wireless access points, VoIP phones, and access control systems directly through Ethernet cables. This eliminates the need for separate power supplies, reducing installation costs and cable clutter while enabling deployment in remote locations.
High-Speed 10 Gigabit Connectivity
Six 10 Gigabit uplink ports deliver the bandwidth your growing network demands. The switch includes 2 x 10GBASE-T copper ports and 4 x 10G SFP+ fiber ports, providing flexible uplink options for long-distance fiber connections or high-speed copper links to core switches and servers. With 168 Gbps switching capacity and 125 Mpps forwarding rate, the DGS-3130-30PS handles demanding traffic loads with ease.
Flexible Stacking for Network Growth
Physical stacking allows you to connect up to 9 units using the 10G SFP+ ports, delivering 80 Gbps of stacking bandwidth per switch. This creates a single manageable unit with up to 324 ports, simplifying network management while providing the scalability your business needs. Stack different DGS-3130 models together to customize your network configuration.
Advanced Layer 3 Routing and QoS
Move beyond basic Layer 2 switching with comprehensive Layer 3 routing features including static routing, RIP/RIPng, and OSPFv2/v3 dynamic routing protocols. These features enable the switch to intelligently route traffic and optimize network efficiency. Rich QoS/CoS features prioritize critical applications like VoIP, video conferencing, IPTV, and IP surveillance, ensuring smooth performance even under heavy network load.
Maximum Network Reliability
Built for mission-critical environments, the DGS-3130-30PS includes multiple redundancy features. Dual power inputs and support for an external redundant power supply ensure continuous operation. G.8032 Ethernet Ring Protection Switching (ERPS) delivers recovery times under 50ms in ring topologies. Additional reliability features include 802.1D/w/s Spanning Tree Protocols, Loopback Detection, and Broadcast Storm Control.
Comprehensive Security Features
Protect your network with advanced security mechanisms including 802.1X port-based authentication, Web-based Access Control (WAC), and MAC-based Access Control. The switch supports multi-layer Access Control Lists (ACL), IP-MAC-Port Binding (IMPB) with DHCP Snooping, and Microsoft Network Access Protection (NAP). Built-in 6kV surge protection on all Gigabit Ethernet ports safeguards equipment from electrical surges and lightning strikes.
Intelligent Management Options
Manage your network with a multilingual web-based GUI, industry-standard CLI via Telnet, or SNMP. The built-in USB 2.0 port enables convenient storage of configuration files, firmware images, and syslog files. The Smart Fan automatically adjusts speed based on temperature to maintain optimal operating conditions while minimizing noise.
