INTRODUCTION

Designed to be adaptive, with unprecedented throughput: 

Atop’s EHG7520 Series offers 24 different versions and 24 making it a very flexible product based on your specific needs. No matter if the 20 port version, this device offers 4 x 1/10 Gigabit Ethernet SFP uplinks making it a cost-effective, reliable industrial solution where high-throughput and high-reliability is fundamental.


Designed for PoE, in wide temperature: 

EHG7520 supports up to 20 Gigabit ports in different configurations, either Copper, PoE or Fiber, any 8-port multiple configuration. Specifically designed for bringing power through Ethernet cable virtually anywhere, a maximum output Power over Ethernet of 240W over a maximum of 8 PoE/PoE+ ports is allowed (802.3af/at).


Rugged, Wide-Temperature, Well protected design:

EHG7520 is EN61000-6-2, EN61000-6-4, IEC/EN/UL62368-1:2014 and FCC certified certified and is designed to withstand the harshest environments and the most demanding EMC environment. Its fanless design and EMC Level 3 protection guarantee reliable operations within -40 and +70°C, guaranteeing no packet is lost with all ports running full power and makes it suitable to be used for almost every application.


Powerful and versatile:

With its high performance, it provides network redundant self-recovery mechanism is less than 20ms on full load that enables the user to build a reliable network through almost any redundant ring topology. EHG7520 supports ITU-T G.8032 ERPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Client), iA-Ring, iA-Chain and many compatible rings protocols for network redundancy. With a Multifunctional web dashboard, its offers intelligent features such as Quality of service (QoS) per port or per VLAN, VLAN, IGMP, Port mirroring and security. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EHG7520 support user account, password policy, and authentication interface managements functions that comply with IEC62443 standard.


Application-Specific:

 NEMA TS-2 Certification makes EHG7520 family the perfect choice for Smart City and Traffic Control applications.
