Designed to be adaptive, with unprecedented throughput: Atop’s EHG7512/16/20 Series offers 24 different versions and 24 making
it a very flexible product based on your specic needs. No matter if the 12, 16 or 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: EHG7512/16/20 supports up to 20 Gigabit ports in different congurations, either Copper,
PoE or Fiber, any 8-port multiple conguration. Specically 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: EHG7512/16/20 is EN61000-6-2, EN61000-6-4, IEC/EN/UL62368-1:2014 and FCC
certied certied 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.
Powerul 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. EHG7512/16/20 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.
Application-Specic:NEMA TS-2 Certication makesEHG7512/16/20 family the perfect choice for Smart City and Trafc Control
