SH-GM020 Series managed industrial switch, supporting Layer 2 network management, and ERPS ring network, is designed for data communication in harsh environments. It features with fanless heat dissipation design, redundant circuit design, wide range of working environment temperature, high protection level, DIN-rail installation, providing excellent industrial-grade quality, which guarantee the reliability and security of industrial networks. It is widely used for network access connectivity in the industries like transportation, telecommunication, security, bank, customs, harbor, power station, oilfield.

• Suport many security control strategies and management: 802.1x authentication, and MAC addresses filtering, storm control function, port mirroring, etc.
• Support carrier-class QoS capability: 8 queues per port, SP (Strict Priority), WRR (Weighted Round Robin) and SP+WRR scheduling algorithms, flow-based QoS, flow-based classification and speed limiting, and port-based bidirectional speed limiting, etc.
• Simple and easy network management: support WEB, CLI, Telnet, SNMP etc.

• Ethernet ring network built through ERPS protocol simplifies deployment and provides redundant links. The failure recovery time <50ms, to ensure uninterrupted network.
• Support one-key configuration of ERPS ring network

• Wide range of working temperature from -40℃ to +85℃, and 5%-95% relative humidity.
• Fanless design, to reduce the power consumption of the device, so the noise.
• Good protection design, like IP40 dust-proof design, lightning protection, anti-surge, anti-interference of fast pulse group, anti-static interference, etc..
• Support DIN-rail, wall-mounted, and desktop installations.
• LED indicators for instant monitoring of the performance status.

• Comply with multiple IEEE802.3at PoE+ and IEEE802.3af PoE standards
• Provides power and data communication over network cable, ideal solution for the application scenario where the traditional power is not available, simplifying and saving the cabling cost
