Designed to be adaptive, with unprecedented throughput: Atop’s EHG7620 Series offers several different versions making it a very flexible product based on your specific needs for Layer-3 Switching. No matter the 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. Layer-3 routing support IPv4 static routing, RIP v1/v2 and OSPFv2. Designed for PoE, in wide temperature: EHG7620 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: EHG7620 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. 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. It supports ITU-T G.8032 ERPS Ring, IEEE802.1D-2004 RSTP, STP, MSTP, MRP (Manager/ Client), iA-Ring, iA-Chain and many compatible rings protocols for network redundancy. With a Multifunctional web dashboard, its offers intelligent features such as QoS, VLAN, IGMP, Port mirroring and security. Application-Specific: NEMA TS-2 Certification makes EHG7620 family the perfect choice for Smart City and Traffic Control applications.
