Description

The SH-GM402400 industrial-grade L2 managed ethernet switch is equipped with 24x1000M and 4x10G SFP slots, balancing Gigabit connectivity and high-bandwidth transmission. The 24x1000M SFP slots support long-distance, anti-interference Gigabit fiber access, making them ideal for linking remote industrial devices like outdoor sensors or distributed control modules. The 4x10G SFP slots, by contrast, focus on high-speed backbone needs—they enable ultra-fast data transfer between network segments, perfectly suiting scenarios like cross-site communication in large industrial parks or real-time transmission of massive production data.

A core advantage of this switch lies in its reliable ring network performance. It supports ERPS 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, port malfunctions, or cable damage—it can rapidly restore connectivity, ensuring uninterrupted communication for critical industrial applications like real-time production control or 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 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 balanced port design (24x1000M + 4x10G SFP), fast fault recovery, and environmental resilience, the SH-GM402400 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.
