Managed L2 Network Switch Ruijie RG-NIS3100-8GT2SFP-HP — 8× Gigabit RJ-45, 2× SFP, PoE, 12–56V DC, 20 Gbit/s, 8000 MAC, Grey

Ruijie RG-NIS3100-8GT2SFP-HP is a managed Layer‑2 network switch offering eight Gigabit RJ‑45 ports and two SFP uplinks. The unit provides PoE support and a MAC address table of 8,000 entries with a switching capacity of 20 Gbit/s. Designed for small office and branch deployments, it accepts a wide DC input range and delivers basic L2 switching, uplink flexibility and centralized management options suitable for compact network environments.

Advantages

The switch combines eight Gigabit copper ports with two SFP slots to support mixed copper and fiber connectivity, enabling flexible uplink or aggregation scenarios. PoE capability allows powered devices to be connected without separate power supplies. Managed L2 features provide control over VLANs, link aggregation and ACLs, while the 20 Gbit/s switching capacity and an 8,000‑entry MAC table support typical small office traffic patterns. Its grey metal enclosure is intended for deployment where a compact, rack or wall‑mountable switch is required.

Suitable for

• Small office networks and branch connectivity
• VoIP phones, wireless access points and IP cameras requiring PoE
• Uplink to core switches or fiber aggregation via SFP ports

How to use

Install the switch in a suitable location with adequate ventilation and mount it according to site requirements. Connect powered devices to the Gigabit RJ‑45 ports and use the SFP slots for fiber uplinks if required. Apply the appropriate DC power source within the 12–56 V range and enable PoE on ports where powered devices are attached. Configure VLANs, link aggregation and ACLs through the switch management interface or the supported cloud/local management tools to integrate the device into your existing network topology.

Recommendations

For stable operation, use a regulated DC power supply that matches the required input range and ensure proper grounding. When deploying PoE devices, calculate total PoE power consumption to avoid exceeding the switch’s PoE budget. Use SFP modules compatible with the switch and follow firmware update procedures from the manufacturer to maintain security and interoperability.
