Managed L2 network switch RUIJIE RG-NIS2100-4GT2SFP-HP — 4× Gigabit RJ45, 2× SFP, PoE++ (180 W), rack/wall/DIN mountable

RUIJIE RG-NIS2100-4GT2SFP-HP is a managed L2 network switch with four Gigabit RJ45 ports and two SFP slots. It provides Power over Ethernet (PoE) including PoE+ and PoE++ (4PPoE) with a total PoE budget of 180 W, supports VLANs, QoS and ERPS, and is designed for rack, wall or DIN-rail installation in a metal, fanless housing. The switch includes an internal DC/PoE power supply (46–57 V) with surge protection and offers web and cloud-based management, DHCP client support and an 8000-entry MAC address table. Its compact dimensions and industrial operating ranges make it suitable for small office, surveillance and edge industrial deployments.

Advantages

The switch combines managed L2 features (VLAN, QoS, ERPS, port mirroring) with PoE++ capability and a 180 W budget, enabling deployment of high-power devices. A fanless metal housing with rack, wall and DIN-rail mounting options supports flexible installation in constrained or harsh environments. Internal DC/PoE power with surge protection and a 5-year warranty provide reliability for continuous operation. Cloud and web-based management plus system logging simplify administration.

How to use

Install the switch in a rack, on a wall or on a DIN rail according to site requirements and secure the provided rack mount kit if needed. Connect the DC/PoE power source within the 46–57 V range and verify surge protection connection. Attach network devices to the Gigabit RJ45 ports or SFP slots; connect PoE-powered devices to the PoE ports, keeping the total PoE consumption within the 180 W budget. Access the device via web interface or cloud management to configure VLANs, QoS, ERPS and other L2 features. Use DHCP client mode if required and monitor system logs to check events.

Recommendations

For reliable PoE deployments, calculate the power draw of connected devices to avoid exceeding the 180 W budget, and place the switch in an environment within the specified temperature and humidity ranges. Use surge-protected cabling and follow grounding best practices in industrial or outdoor installations.
