20 Ports Industrial L2 Managed Ethernet Switch 16×10/100/1000M RJ45 Ports + 4x1000M SFP Slots

The SH-GM04016 industrial-grade L2 managed ethernet switch is equipped with 16×10/100/1000M RJ45 ports and 4x1000M SFP fiber ports. The 16 RJ45 ports offer high-density connectivity for local industrial terminals—such as control panels, high-definition surveillance cameras, and smart sensors—while the 4 SFP ports enable long-distance, anti-interference fiber transmission, making it ideal for industrial networks that need both extensive terminal access and wide coverage.

In terms of network reliability, the switch supports ERPS ring networks and one-click ring network setup, and strictly complies with the G.8032 ERPS Ethernet ring network protection switching protocol. It achieves a self-healing time of within 20 milliseconds: if a network failure occurs (e.g., fiber breakage or port malfunction), it can quickly restore network links to avoid service downtime, ensuring uninterrupted communication for critical industrial applications like real-time production control or safety monitoring systems.

Built to withstand tough industrial conditions, the switch operates stably across a wide temperature range of -40°C to +85°C. Whether deployed in freezing outdoor electrical cabinets (such as road traffic control units in cold northern regions) or high-heat industrial sites (like oilfield production workshops), it maintains consistent performance without being affected by extreme temperature fluctuations or harsh environmental factors (e.g., dust, humidity).

Moreover, the switch supports layer-2 network management functions, allowing users to manage and configure it through four intuitive interfaces: Web, Telnet, Console (CLI), and SNMP. This flexibility adapts to different operation and maintenance workflows—for example, IT teams can use Web interfaces for visual configuration, while advanced users can opt for CLI for efficient command-line operations—simplifying tasks like device status monitoring, traffic management, and fault troubleshooting.

Thanks to its high-port-density design, fast fault recovery, and robust environmental resilience, the SH-GM04016 is widely applied in diverse industrial scenarios. These include industrial control automation, road traffic control automation, building automation systems, mine automation systems, oilfield control automation, hydropower station control automation, power system control automation, and computer room monitoring systems—providing reliable, efficient network support for core industrial operations.
