28 Ports Industrial L2 Managed Ethernet Switch 16x1000M +4x10G SFP Slots + 8 Combo Ports

The SH-GM481600 industrial-grade L2 managed Ethernet switch is equipped with three flexible port types: 16x1000M SFP slots, 4x10G SFP slots, and 8 groups of Combo ports. The 16x1000M SFP slots support long-distance Gigabit fiber transmission, ideal for connecting remote industrial devices (e.g., sensors in outdoor workshops). The 4x10G SFP slots focus on high-bandwidth backbones, enabling ultra-fast data transfer for cross-site communication or large-volume real-time data needs (such as factory-wide production monitoring). Meanwhile, the 8 Combo ports add versatility—each group allows switching between copper or optical connectivity, adapting to mixed wiring environments (e.g., using existing copper cables for nearby devices and fiber for distant ones).

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 multi-type port design (16x1000M SFP + 4x10G SFP + 8 Combo), fast fault recovery, and environmental resilience, the SH-GM481600 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, flexible network support for core industrial operations.
