28 Ports Industrial L2 Managed Ethernet Switch 16×10/100/1000M RJ45 + 4x10G Fiber + 8xCombo Ports

The SH-GM480016 industrial-grade L2 managed switch comes with three types of ports for versatile connectivity: 16×10/100/1000M RJ45 copper ports, 8 groups of Gigabit optical-electrical multiplexing ports, and 4x10G SFPs. The 16 copper ports handle high-density local terminal access, easily linking devices like industrial controllers and IP cameras. The 8 optical-electrical multiplexing groups add flexibility—users can choose either Gigabit copper or optical transmission for each group, adapting to mixed wiring environments (e.g., combining existing copper cables and new fiber links). Meanwhile, the 4x10G SFPs focus on high-bandwidth backbones, enabling ultra-fast data transfer for cross-site communication or large-volume real-time data needs.

A core advantage of this switch is its reliable ring network support. It enables ERPS ring networks and offers a one-click ring network function, simplifying deployment even for teams with limited on-site technical experience. 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 rapidly restores connectivity, ensuring uninterrupted communication for critical industrial applications like real-time production control or safety monitoring systems.

Built to withstand harsh industrial conditions, 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, reducing 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 versatile port design (16 copper + 8 multiplexing + 4 10G SFPs), fast fault recovery, and environmental resilience, the SH-GM480016 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, flexible network support for core industrial operations.
