Switch managed Ruijie Networks RG-NIS3100-4GT2SFP-HP L2 Gigabit Ethernet PoE

The Ruijie Networks RG-NIS3100-4GT2SFP-HP L2 Gigabit Ethernet PoE is a managed switch designed for small to medium network deployments requiring Power over Ethernet and flexible power input. The device provides four Gigabit RJ-45 ports with PoE capability and two SFP slots for fiber uplinks or media conversion. With a switching capacity of 12 Gbit/s and a MAC address table of 8000 entries, this switch supports efficient frame forwarding and simplified layer 2 network management. The unit accepts a DC input voltage range of 12–56 V, allowing use with a variety of power supplies and environments where flexible DC sourcing is needed.

Advantages

The switch offers managed L2 features in a compact, grey enclosure with four Gigabit Ethernet ports and PoE support, enabling centralized control and power delivery to endpoints over existing copper links. Its two SFP slots permit fiber connectivity or extended-distance uplinks while the 12 Gbit/s switching capacity and 8000-entry MAC table provide adequate performance for typical access-layer roles. The wide DC input range increases deployment options in sites with different DC power sources.

Suitable for

• Small office and branch access layer with connected IP phones and wireless access points
• Network edge installations requiring fiber uplinks or media conversion
• Power over Ethernet deployments for cameras, APs, and VoIP devices

Key specifications

• Switch type: Managed L2
• RJ-45 ports: 4 × Gigabit Ethernet (10/100/1000)
• SFP slots: 2 × SFP for fiber uplink (media dependent)
• Switching capacity: 12 Gbit/s
• MAC address table size: 8000 entries
• Power input: DC 12–56 V
• Colour: Grey

How to use

Install the RG-NIS3100-4GT2SFP-HP in a suitable rack or on a flat surface with adequate ventilation. Connect copper devices to the four Gigabit RJ-45 ports; attach SFP transceivers to the SFP slots if fiber uplinks are required. Provide compatible DC power within the 12–56 V range to the power input. Access the management interface via the console, web GUI or supported management protocols to configure VLANs, PoE settings, link aggregation and other layer 2 features appropriate to your network design. Monitor the MAC address table and link status to ensure expected connectivity.

Recommendations

Use PoE budget planning to ensure connected devices do not exceed the switch's available power; separate critical uplinks onto SFP fiber where longer distance or electrical isolation is required. Keep firmware updated and configure management access controls to secure the switch in managed deployments.
