28 Ports Industrial L2 Managed Ethernet Switch 24×10/100/1000M RJ45 Ports + 4x10G SFP Slots

The SH-GM400024 industrial-grade L2 managed ethernet switch is equipped with 24×10/100/1000M copper ports and 4x10G 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 that require centralized access to multiple terminals (e.g., large workshop control systems or building automation hubs). Meanwhile, the 4 10G SFP ports focus on high-bandwidth, long-distance transmission; they enable ultra-fast data transfer for industrial network backbones, perfectly suiting needs like cross-site high-speed communication or large-volume data transmission in factories.

A core advantage of this switch lies in its reliable ring network performance. It supports ERPS (Ethernet Ring Protection Switching) ring networks and offers a one-click ring network function, which simplifies deployment for on-site teams even with limited technical expertise. It also strictly complies with the G.8032 ERPS Ethernet ring network protection switching protocol, with a self-healing time of within 20 milliseconds. When network failures occur—such as fiber breaks, copper cable damage, or port malfunctions—it can rapidly restore connectivity, ensuring uninterrupted communication for critical industrial applications like real-time production monitoring and 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 (like road traffic control units in cold northern regions) and holds up in high-heat, dusty industrial sites (such as oilfield production workshops or mine control rooms). It also resists humidity and sudden temperature fluctuations, minimizing 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, 10G high-bandwidth ports, fast fault recovery, and environmental resilience, the SH-GM400024 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, high-speed network support for core industrial operations.
