Ports & Connectivity
8 × Gigabit RJ45 (10/100/1000 Mbps) — for connecting computers, APs, printers, and other Ethernet devices.
2 × Gigabit SFP uplink ports — for fiber connectivity or long‑distance backbone links to other switches or routers.
Non‑PoE design: No built‑in power delivery on RJ45 ports — ideal when powering devices separately or when PoE isn’t required.
⚙️ Performance & Hardware
Switching capacity: 20 Gbps — helps ensure all ports can handle full wire‑speed traffic without bottlenecks.
Forwarding rate: ~14.88 Mpps — good performance for typical small‑to‑medium business traffic loads.
Jumbo frame support: Up to 9216 bytes (MTU) for improved large‑packet performance.
Surge protection: Up to ±6 kV on service ports and additional protection on power connectors for electrical resilience.
Operating temperature: 0 °C to +50 °C — suitable for standard indoor environments.
MTBF: ~400,000 hours of operational reliability.
Warranty: 5 years backing from manufacturer.
☁️ Cloud & Management
Ruijie Cloud management: Lifetime support via Ruijie Cloud and the Reyee mobile app for remote monitoring, configuration, and troubleshooting from anywhere.
Zero‑touch provisioning (SON): Automatically configures the switch when added to a cloud project — simplifies deployment and cuts onsite setup time.
Local management: eWeb GUI plus SNMP support for integration with existing network tools or local control.
🔐 Layer 2 Features & Security
The switch provides a set of enterprise‑class Layer 2 and security features including:
VLAN support: Segment traffic for departments or services (up to many VLANs).
Link Aggregation (LAG): Combine multiple ports to increase throughput and redundancy.
IGMP Snooping: Optimizes multicast traffic (useful for CCTV or IPTV).
Port isolation & broadcast storm control: Helps maintain network stability and security.
IP camera recognition: Detects and classifies IP camera traffic to prioritize or optimize video streams.
🏢 Use Cases & Scenarios
This switch is a good fit for:
✅ Small & medium business LANs needing reliable, managed Gigabit connectivity.
✅ Office and retail environments where PoE isn’t required or is supplied separately.
✅ Connections to fiber backbones via the SFP uplinks.
✅ IP CCTV networks where video streams need prioritization and stable throughput.
✅ Campus or branch deployments managed centrally through the cloud.
