52 Ports Industrial L2 Managed Ethernet Switch 48×10/100/1000M RJ45 Ports + 4x10000M SFP Slots

The SH-GM400048 industrial-grade L2 managed ethernet switch is equipped with 48×10/100/1000M copper ports and 4x10G SFP slots. The 48 copper ports deliver ultra-high-density local connectivity, easily linking large batches 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 massive terminals (e.g., large-scale factory workshops or multi-floor building automation systems). Meanwhile, the 4x10G SFPs focus on high-bandwidth backbone transmission; they enable ultra-fast data transfer between network segments, perfectly suiting needs like cross-site high-speed communication or large-volume real-time data transmission in industrial parks.

A core strength of this switch lies in its reliable ring network performance. It supports ERPS ring networks and offers one-click ring network setup, which simplifies deployment for on-site teams even with limited technical expertise. It also adheres strictly to the G.8032 ERPS Ethernet ring network protection switching protocol, with a self-healing time of up to 20 ms. 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 control and safety monitoring systems.

Built to withstand harsh industrial environments, the switch operates stably across a wide temperature range of -40°C to +85°C. It maintains reliable performance in extreme scenarios: for example, it works steadily 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.

Moreover, 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 48-port ultra-high-density design, 10G high-bandwidth SFPs, fast fault recovery, and environmental resilience, the SH-GM400048 is widely used 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.
