Flexible and cost-effective, this is an ideal industrial solution where high-throughput and high-reliability are fundamental.

Unprecedented throughput and power:
ATOP’s EHG7512/16/20 Series offers 24 versions of up to 20 Gigabit ports, with different port configurations in copper, PoE or fiber, all of which include 4 x 1/10 Gigabit Ethernet SFP uplinks.
Specifically designed for bringing power through Ethernet cables virtually anywhere, it supports a maximum of 8 PoE/PoE+ ports (802.3af/at) to produce up to 240W Power over Ethernet output.

Rugged and reliable:
This switch series is EN61000-6-2, EN61000-6-4, IEC/EN/UL62368-1:2014 and FCC certified, able to withstand the harshest environments and the most demanding EMC environment for almost any application. NEMA TS-2 certification further ensures that it is the perfect choice for smart cities and traffic control. Its fanless design and EMC Level 3 protection guarantee reliable operations between -40 and +70°C, and zero packet loss even with all ports running full power.

High-performance network redundancy functions provide self-recovery in less than 20ms on full load, enabling a reliable network through almost any redundant ring topology such as ITU-T G.8032 ERPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Manager/Client), iA-Ring, and iA-Chain.

Secure and smart:
To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EHG7520 supports user account, password policy, and authentication interface management functions that comply with IEC62443 standards. The multifunctional web dashboard also offers further intelligent features such as Quality of service (QoS) per port or per VLAN, VLAN, IGMP and port mirroring.
