The industry's first! Xinhua Sanxun launches the intrinsically safe 10G industrial Ethernet switch

Recently, New H3C Group, a subsidiary of Tsinghua Unigroup, released the industry's first intrinsically safe 10 Gigabit Industrial Ethernet switch. The product integrates high-quality electrical circuit design, mature software functions and advanced network protocols, leading the mining safety core network capabilities to a new level, and building a solid digital foundation for harsh industrial scenarios such as smart mines with higher performance and higher precision network connections.

High performance + high precision + high security, building a network connection that better understands mining scenarios

Mines are typical application scenarios for industrial networks. As the process of intelligent mine construction continues to accelerate, various national ministries and commissions have successively issued policies such as "Guiding Opinions on Accelerating the Development of Intelligent Coal Mines" and "Guidelines for Intelligent Coal Mine Construction (2021 Edition)" to point the way for building a new generation of intelligent mining area networks. Among them, the hard indicators of infrastructure have also become an important scoring item for the country's requirements for backbone network specifications, and clearly require that switch products must meet intrinsic safety standards and take into account high performance, intrinsic safety explosion-proof, small size, and easy maintenance.

Due to the particularity of mining production scenarios, the design requirements for switch products in terms of voltage, current, energy storage components, circuit isolation and electrical clearance are much stricter than those for ordinary industrial switches. The intrinsically safe 10G industrial Ethernet switch H3C IE4520 launched by H3C Group integrates multiple technological innovations such as high-quality electrical circuit design, plate processing, high-precision manufacturing and advanced network protocols, fully meeting the needs of efficient, reliable, intelligent and visible mining network construction.

● Strictly follow the intrinsic safety standards: The main design of the product fully meets the requirements of the Exib standard. The whole machine design does not require a heavy special explosion-proof shell. The intrinsic safety level design fundamentally solves the risk of sparks and explosions, and the system is safer. The product weight can be controlled within 10kg, which is 90% lighter than the previous generation. It can be installed and deployed by one person and is easy to operate and maintain later.

● Leading performance and accuracy: 6 10G Ethernet optical interfaces can realize high-speed ring network backbone connection, 8 Gigabit electrical interfaces and 4 Gigabit optical interfaces can meet the access capabilities of various services such as underground video monitoring and Wi-Fi 6 access, and the RS485 communication interface can connect various environmental sensor data to meet the needs of underground environmental monitoring data collection. The product has a high-precision 1588V2 clock, and the clock synchronization accuracy deviation can be controlled within plus or minus 8ns, ensuring that the ring network self-healing time can be less than 15ms, which is much lower than the 50ms required by the national standard and is more than 70% better than the industry average.

● Software and hardware integration: The product is equipped with H3C Comware operating system, meets the full IPv6 protocol and supports SDN capabilities. It can actively report various types of refined status information of the equipment itself at intervals of seconds. Through the H3C iMC intelligent management center, it can realize the visual management of underground networks and the refined control of traffic, as well as the fault diagnosis and fault prediction functions of optical links, helping users to build an intelligent and visual high-speed mining network. Based on the open hardware architecture, more advanced network functions can be smoothly realized through software upgrades in the future.

● Comprehensive security protection mechanism: The product has four layers of security protection. At the business level, it supports URPF detection, anti-ARP attack, and DDoS attack functions; at the traffic control level, it supports sophisticated ACL/QoS scheduling functions to flexibly control the allocation of network resources; at the terminal access level, it supports EAD access policies to prevent illegal terminal access; at the device protection level, it supports CPU protection to prevent protocol packets from maliciously occupying CPU resources.

Rich industrial product layout, actively responding to the development trend of the new era network

As a leader and enabler of network evolution and transformation, H3C Group not only shines in the Ethernet switch market, but also has a rich product layout in industrial scenarios. Based on in-depth insights into customer needs, H3C has successively released more than 40 industrial switches with features such as radiation resistance, electromagnetic interference resistance, high and low temperature resistance, earthquake resistance, high security, and easy maintenance, and has achieved large-scale deployment in industries such as rail transit, electric power, and high-end manufacturing. Its customers cover more than 90% of electric power companies, and the rail transit industry ships more than 10,000 units per year, continuously contributing to the booming urban rail construction. At the same time, in the high-end manufacturing industry, H3C actively participates in the cutting-edge research of TSN (time-sensitive network). By combining TSN technology with its own hardware equipment, it has achieved many results in TSN product creation, technology integration, and ecological construction.

Looking to the future, H3C will rely on the "Cloud Native" strategy to further focus on investment in industrial scenarios, closely focus on user needs, and enable the innovative development and digital transformation of hundreds of industries with full-stack, all-round network solutions.
