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 EHG7704/06/08(C)/11 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: EHG7704/06/08(C)/11 series provide, in its 8-PoE-Port Version, up to 90W per port and total 180 W power budget. The “C” models provide total 120 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, EHG7704/06/08(C)/11 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. |
