The EHG7711 Series is an Industrial Grade Managed Gigabit Ethernet PoE Switch. UL, CE and FCC certified, it provides highly reliable, fault tolerant, extremely fast network connections in harsh environments.   Versatile high performance: Within its compact DIN-Rail slim type housing design, the EHG7711 series allows you to choose between different port combinations: 1G BASE-T(X) RJ45, IEEE 802.3af/at/bt compliant PoE RJ45, 1G BASE-X SFP and 2.5G Base-X SFP, achieving maximal network performance to suit your exact needs.   High power and redundancy: EHG7711 series provide, in its 8-PoE-Port Version, up to 90W per port and total 180 W power budget. All models have two terminal blocks to provide dual redundant power inputs with reverse polarity protection, enabling stand-alone fault alarm systems.   Reliability and security: Set up a reliable network environment through RSTP, ERPS Rings and MRP (Manager/Client) redundancy and keep equipment connected all the time, even in case of temporary network breakdowns. And to prevent network intrusions, EHG7711 supports user account, password policy, and authentication interface managements functions that comply with the IEC62443 standard.   Industry-specific features: Having undergone environmental testing to ensure reliable performance under a variety of power supply conditions, this switch series is fully compliant for today’s demanding railway applications, as well as complying with essential ground equipment standards. It can also function as an IEEE 1588 hardware-based boundary or transparent clock, offering precise transmission for time-sensitive processes.   APPLICATION CASES As the capabilities of connected devices continue to improve with technologies like 5G and Wi-Fi 6, networks must also be able to handle faster transmission speeds. 2.5 Gigabit Ethernet (2.5 GbE) supports speeds between 1Gbps and 10Gbps, achieving upgrade for network performance without a complete infrastructure overhaul. The EHG77xx switch is equipped with 2.5 Gbps SFP slots, making it a powerful tool for connecting advanced applications such as high-resolution CCTV and public Wi-Fi. It can replace slower switches in existing topologies, allowing old and new devices to operate at their full potential. On the other hand, applications like pan-tilt-zoom (PTZ) cameras and devices that work under extreme weather conditions need higher power, over 30 W, to operate. EHG77xx’s 802.3bt PoE ports provide up to 90 W per port, eliminating the need for additional power supply and cables on-site.
