The "2024 China Smart Manufacturing Development Report" indicates that China's smart manufacturing market surpassed 4 trillion yuan in 2023 and is projected to reach 5 trillion yuan by 2025, maintaining an annual compound growth rate exceeding 18%. However, traditional industrial network equipment struggles to adapt to complex and variable industrial environments, often resulting in unstable connections, weak anti-interference capabilities, and low management efficiency, thus becoming a bottleneck in enterprises' intelligent transformation.

According to real-time reports from Sina Technology and China Communications Network, Yuhang Industrial Switches, one of the top ten industrial switch brands, has launched Layer 2/3 managed switch series. These switches, with high reliability, flexible networking capabilities, and intelligent management functions, are setting new benchmarks in industrial network infrastructure, providing strong support for enterprises' digital transformation.

1. Intelligent Networking and Efficient Management: Building Agile Industrial Networks

In modern industrial scenarios, the demand for device interconnection is increasingly complex, requiring higher network flexibility and management efficiency. Yuhang's Layer 2/3 managed switch series offers advanced network protocols and intelligent management features, providing enterprises with one-stop network solutions.

Yuhang Industrial Switch Feitian Series: YH624GS-M-SFP Example:

• Full Gigabit High-Speed Transmission: Equipped with 4 10/100/1000M adaptive RJ45 ports and 2 Gigabit SFP fiber ports, supporting MDI/MDI-X auto-sensing, easily achieving hybrid optical-electrical networking. With a 38G backplane bandwidth and switching delay under 10μs, it ensures high-speed, non-blocking data transmission.

• Multiple Redundancy Protections: Supports STP/RSTP/MSTP multiple spanning tree protocols and ERPS ring network protection technology, enabling rapid switching to backup paths during link or node failures, effectively preventing production stagnation due to network interruptions.

• Refined Traffic Control: Supports Port-based VLAN and IEEE 802.1Q VLAN for logical isolation of different business systems; QoS (IEEE 802.1p/1Q) and TOS/DiffServ technologies allocate priority and bandwidth for critical services; also supports port rate limiting, broadcast storm suppression, multicast storm suppression, and unknown unicast storm suppression to prevent network congestion.

2. Industrial-Grade Reliable Design: Tackling Harsh Environmental Challenges

Industrial environments are complex and variable, posing severe tests for network equipment durability. Yuhang industrial Ethernet switch adopt full industrial-grade designs to ensure reliable operation under extreme conditions.

• Wide Temperature and Voltage Design: Yuhang's aluminum alloy series products operate within a temperature range of -40°C to 85°C, with the same storage temperature range, and relative humidity adaptability from 5% to 95% (non-condensing). They can operate stably in cold outdoor monitoring systems or high-temperature smelting workshops. Power input supports a wide voltage range of DC12-52V, with dual power redundancy design ensuring power reliability, built-in 4.0A overcurrent protection, and reverse polarity protection enhancing safety.

• Excellent Electromagnetic Compatibility: As a founding unit of China's domestic industrial switches, Yuhang possesses strong technical capabilities. Even in industrial sites with severe electromagnetic interference, Yuhang's industrial switch series can pass stringent EMC tests, including ±8kV contact discharge and ±15kV air discharge ESD protection, and ±6kV CM/±4kV DM surge protection on network ports, effectively resisting various electromagnetic interferences.

• Robust and Durable Design: Yuhang's aluminum alloy series products feature IP40 protection grade aluminum alloy enclosures, effectively dustproof and moisture-proof; they pass IEC 60068-2-27 shock test, IEC 60068-2-32 free fall test, and IEC 60068-2-6 vibration test, ensuring stable operation in vibration-prone industrial environments. The fanless natural cooling design significantly reduces fan failure risks, with a mean time between failures (MTBF) of up to 300,000 hours, coupled with a 5-year warranty, greatly reducing equipment replacement and maintenance costs.

3. Intelligent Security Operations: Strengthening Industrial Network Defense

As industrial networks deeply integrate with the internet, network security threats are increasing, and operation and maintenance management are becoming more challenging. Yuhang's Layer 2/3 managed switch series integrates multiple security protections and intelligent operation and maintenance functions to achieve visualized and intelligent network management.

• Multi-Level Security Protection: Supports IEEE 802.1x authentication, ACL access control lists, RADIUS authentication, and user hierarchical management to build a multi-level security protection system; supports MAC address binding to effectively prevent unauthorized devices from accessing the network.

• Visual Management Platform: Supports Web and SNMP v1/v2/v3 management methods, allowing administrators to configure network parameters and monitor network status through an intuitive Web interface; also supports RMON remote monitoring to enhance network prediction capabilities.

• Intelligent Diagnostics and Alerts: Supports port mirroring for network fault diagnosis; interface status monitoring and log management to grasp network operation status in real-time; alert functions support power, port, and abnormal status relay outputs to promptly detect and handle potential faults.

4. Diverse Application Scenarios: Empowering Industry Digital Transformation

Yuhang's Layer 2/3 managed switch series, with its excellent performance and reliability, plays a key role in various industry fields:

• Smart Factories: Provides highly reliable communication networks for production lines, supporting interconnection of PLCs, robots, AGVs, and other devices to achieve intelligent production processes.

• Intelligent Transportation: Applied in highway monitoring systems and intelligent traffic signal control to ensure real-time transmission and processing of traffic data.

• Energy Management: Enables remote monitoring and control of equipment in wind farms, photovoltaic power stations, and substations, improving energy management efficiency.

• Security Monitoring: Provides stable transmission networks for video surveillance systems, supporting lossless transmission of high-definition video streams to enhance the reliability of security systems.

Conclusion: A Solid Foundation for Digital Transformation

Yuhang's full range of industrial switches, with their various advantages and excellent performance and reliability, are becoming the backbone of industrial network infrastructure. In today's rapidly developing industrial internet era, Yuhang industrial Ethernet switch offer not just industrial network equipment but also a solid foundation for enterprises' digital transformation. By building efficient, secure, and reliable industrial networks, they are helping various industries achieve intelligent upgrades and integrate into the new era of Industry 4.0.
