Quality Certifications

The recycling symbol signals that products or packaging are designed for recyclability, aligning with global waste management practices to promote sustainability.

RoHS compliance restricts the use of hazardous substances like lead and mercury in electronics, protecting human health and minimizing environmental impact.

FCC certification ensures electronic devices sold in the US meet electromagnetic and radio frequency standards, safeguarding against communication signal interference.

The CE mark confirms that products comply with EU safety, health, and environmental regulations, allowing seamless market access across the European Economic Area.

Description

The SH-GM0204T industrial-grade managed ethernet switch provides 4*10/100/1000Base-T Ethernet POE ports and 2*1000Base-FX SFP slots. It supports ERPS ring network and one-click ring network setup, as well as the G.8032 ERPS Ethernet ring network protection switching protocol, with a self-healing time within 20ms. When a network failure occurs, it can quickly recover to ensure uninterrupted communication for critical applications. It supports a wide operating temperature range of -40~+85℃, ensuring stable operation of the device in harsh environments. In addition, it supports Layer 2 network management functions, allowing management and configuration of the device via Web, Telnet, Console (CLI), and SNMP. It is widely used in industrial application scenarios such as industrial control automation, road traffic control automation, building automation systems, mine automation systems, oilfield control automation, hydropower station control automation, power system control automation, and equipment room monitoring systems.

The SH-G0204T series industrial-grade POE switches also support POE output, providing power to front-end PD devices such as network cameras and wireless APs, and are suitable for occasions where traditional wire routing is inconvenient.
