Ruijie Reyee Industrial L2 Switch, 4×Gigabit PoE + 2×SFP, RG‑NIS2100‑4GT2SFP‑HP

Introduction to the Ruijie Reyee RG-NIS2100-4GT2SFP-HP and its key features

The Ruijie Reyee RG-NIS2100-4GT2SFP-HP is a compact, cloud-managed L2 industrial Ethernet switch built for demanding environments and edge PoE deployments. It combines four Gigabit RJ-45 downlinks with PoE capability and two 1 Gbps SFP uplinks in a fanless, aluminium IP40 enclosure designed for DIN-rail or wall mounting. Key selling points include wide operating temperature range (−40 °C to +75 °C), industrial surge and EMC protection, and management through Ruijie Cloud and the Reyee mobile app. With a suggested price point of 169.0 (cost price 136.8), this model targets small CCTV and industrial networking projects where rugged hardware, PoE at the edge, and remote manageability matter.

Detailed specifications and benefits

The RG-NIS2100-4GT2SFP-HP packs a surprising set of industrial features into a small footprint. Below is a concise breakdown of its specifications and the practical benefits each delivers.

• Ports:4 × 10/100/1000Base-T RJ-45 downlink ports and 2 × 1 Gbps SFP uplinks. The mixture of copper PoE downlinks and fibre-capable SFP ups makes the unit flexible for edge scenarios: local cameras or access points plugged into the RJ-45 ports, and uplinked to a central switch or NVR via SFP for longer distances or noise immunity.
• PoE:Vendor materials highlight a 90 W total PoE output, while some reseller listings report higher totals (120 W or 180 W). The advertised port layout is 1 × PoE++ plus 3 × PoE+ ports. Important: verify the exact per-port and total budget in the official datasheet or on the unit before planning powered devices. The potential to power multiple PoE cameras or APs directly from the switch simplifies installations and reduces cabling and adapter clutter.
• Performance:Reported switching capacity is approximately 12 Gbps with a forwarding rate near 8.9 Mpps, an MAC table around 8,000 entries and a packet buffer of roughly 4.1 Mbit. For small CCTV and control networks, these figures are more than adequate for aggregated Gigabit uplinks and multi-camera PoE deployments.

• Power input:Reported DC input range of 46–57 V (verify in the datasheet/installation guide). A compatible power source is required; note that a power adapter is not included by default.
• Operating temperature:−40 °C to +75 °C—this makes the unit suitable for unconditioned cabinets, cold climates, and hot industrial environments when airflow is limited.
• Surge & EMC protection:6 kV surge protection (reported) and EMC level 4 provide resilience against electrical disturbances common in industrial and outdoor-adjacent sites. Proper earthing and following installation guides are essential to maintain these protections.

• Enclosure & mounting:IP40 aluminium chassis, fanless design, supports both DIN-rail and wall mounting. The compact dimensions (approx. 155 × 130 × 50 mm) and light weight (~0.77 kg) simplify cabinet and rackless deployments.
• Management:Full L2 feature set with ERPS fast failover and remote management via Ruijie Cloud and the Reyee app. Cloud-managed visibility and configuration make it easier to deploy and maintain distributed sites without frequent on-site visits.
• Warranty & documentation:Vendor warranty listed as 5 years (some resellers list 36 months—verify regionally). Documentation such as datasheets, installation guides and implementation cookbooks are available from Ruijie Reyee for installers and integrators.

Use cases and scenarios where this switch excels

The RG-NIS2100-4GT2SFP-HP is tailored for edge and small-site industrial networking. Typical scenarios include:

• CCTV camera networks:Small to medium multi-camera installations benefit from the PoE ports and rugged operation. The mix of PoE and SFP uplinks lets you place the switch close to cameras and use fibre or long copper uplinks to central NVRs.
• Coastal or outdoor cabinets (with enclosure):With proper IP-rated enclosures, the unit’s temperature range and surge protection make it suitable for harsh coastal or exposed installations where commercial-grade switches would fail.
• Edge PoE deployments:Locations that need to power access points, IoT gateways, or field controllers without a conditioned room—such as warehouses, small substations, kiosks or parking structures—benefit from the compact, fanless design.
• Small industrial control networks:For local PLC connections, HMIs, or sensor aggregation, the switch’s L2 features and ERPS fast failover provide predictable behaviour with limited management overhead.
• Distributed sites and managed services:Integrators managing multiple remote sites can use Ruijie Cloud for centralized configuration, monitoring and firmware updates, reducing truck rolls and onsite troubleshooting time.

Comparisons with similar products in the market

When evaluating the RG-NIS2100-4GT2SFP-HP, it helps to compare it by category rather than single numbers. Here are useful comparison angles:

Compared with commercial indoor PoE switches, the RG-NIS2100 offers broader operating temperature and enhanced surge/EMC protection—features essential for non-climate-controlled or electrically noisy sites. Commercial switches may offer more ports at similar prices but lack the environmental ratings required for outdoor cabinets or industrial floors.

The device provides core L2 features (VLANs, link aggregation, ERPS fast failover) and cloud management. Higher-end industrial switches from specialist vendors may include advanced L3 routing, redundant power inputs, or certified industrial protocols (e.g., IEC 61850, PROFINET) and wider voltage input ranges; those are necessary for large process automation or mission-critical control systems but come at a significantly higher cost.

At a suggested price near 169.0, the RG-NIS2100 positions itself as a cost-effective industrial PoE switch for edge sites. Competitors with similar environmental ratings and PoE capacity can be more expensive, while cheaper alternatives often sacrifice temperature range, surge protection or managed features. For many CCTV and small control applications, this model offers a strong balance of ruggedness, PoE capability and cloud management.

Customer feedback and typical reviews

While full third-party review data is limited in this listing, common themes from reseller pages and user comments can be summarized as follows:

• Positive feedback:Installers frequently praise the compact size, rugged aluminium chassis and the wide temperature range—particularly for deployments in outdoor cabinets or non-air-conditioned rooms. Users appreciate the convenience of Ruijie Cloud management for remote monitoring and firmware updates, which reduces maintenance overhead for distributed sites.
• Constructive critiques:The most repeated point is the ambiguity around total PoE budget—some reseller descriptions list higher totals than the vendor’s highlight (90 W), so integrators advise verifying the datasheet or the sticker on the unit before sizing PoE devices. Another common note is that the power adapter is not included, so purchasers must plan for the correct DC input supply and wiring.
• Operational notes:Reports indicate reliable operation in modest CCTV and small control networks. Where users require higher port counts, full L3 routing or certified industrial protocol support, they often migrate to higher-tier industrial switches that are more expensive and larger.

Conclusion: Why this switch is a great choice

The Ruijie Reyee RG-NIS2100-4GT2SFP-HP is a compelling option for integrators and IT teams that need a compact, rugged, and remotely manageable PoE switch at the network edge. Its combination of four Gigabit PoE ports, dual SFP uplinks, wide operating temperature, and industrial surge/EMC protection makes it well-suited to CCTV, edge PoE and small industrial control deployments. The availability of Ruijie Cloud and the Reyee app simplifies deployment and ongoing management of distributed sites.

Key considerations before purchase are straightforward: confirm the exact PoE budget and per-port power allocation from the official datasheet or the physical unit; plan for the required DC power source (adapter not included); and follow installation guides for proper mounting and earthing to maintain surge protection effectiveness. For projects that fit its capabilities—edge camera clusters, small outdoor cabinets, or remote AP/IoT aggregation—the RG-NIS2100 offers a durable, cost-conscious choice with the conveniences of cloud management and industrial-grade protection.
