28 Ports Industrial L2 Managed Ethernet Switch 24×10/100/1000M Copper Ports +4x1000M SFP Slots

The SH-GM04024 industrial-grade L2 managed Ethernet switch is equipped with 24×10/100/1000Base-T copper ports and 4x1000M SFP slots. The 24 copper ports deliver high-density local connectivity, easily linking a large number of on-site industrial devices—such as control modules, high-definition IP cameras, and smart sensors—making it ideal for scenarios where multiple terminals need centralized access (e.g., large workshop control systems or building automation hubs). Meanwhile, the 4 SFP slots support long-distance, anti-interference fiber transmission; by inserting compatible 1000M SFP modules, these slots extend network coverage to remote areas, balancing local access and cross-site connectivity needs.

A key strength of this switch is its reliable ring network support. It enables ERPS (Ethernet Ring Protection Switching) ring networks and offers a one-click ring network function, simplifying deployment for on-site teams even with limited technical experience. It also strictly complies with the G.8032 ERPS Ethernet ring network protection switching protocol, with a self-healing time of within 50 milliseconds. When network failures occur—like fiber breaks, copper cable disruptions, or port malfunctions—it can rapidly restore connections, ensuring uninterrupted communication for critical industrial applications such as real-time production monitoring or safety control systems.

Built to withstand harsh industrial environments, the switch operates stably across a wide temperature range of -40°C to +85°C. It maintains consistent performance in extreme scenarios: for example, it works reliably in freezing outdoor electrical cabinets (such as road traffic control units in cold northern regions) and holds up in high-heat, dusty industrial sites (like oilfield production workshops or mine control rooms). It also resists humidity and sudden temperature fluctuations, reducing the risk of downtime caused by environmental stress.

In addition to its rugged hardware, the switch supports comprehensive layer-2 network management functions. Users can manage and configure the device through four intuitive interfaces: Web, Telnet, Console (CLI), and SNMP. This flexibility adapts to different operational habits—some teams may prefer visual Web-based settings for quick parameter adjustments, while advanced technicians can use CLI for efficient command-line operations—simplifying daily tasks like device status checks, traffic optimization, and fault troubleshooting.

Thanks to its 24-port high-density design, flexible fiber expansion, fast fault recovery, and environmental resilience, the SH-GM04024 is widely applied in diverse industrial scenarios. These include industrial control automation, road traffic control automation, building automation control systems, mine automation control systems, oilfield control automation, hydropower station control automation, power system control automation, and computer room monitoring systems. In all these fields, it provides stable, efficient network support for core industrial operations.
