Datasheet   Manual  


The Lantech IES-2008B is an 8-port 10/100BaseTX SNMP industrial Ethernet switch with Pro-Ring IIs self-recovery scheme in 20ms. The advanced SNMP management features include QoS for 4 queues, 802.1q VLAN, IGMP snooping, query and source only for multicast IP surveillance, SSH/SSL* as well as Web Ping, CPU load monitoring, SNTP and SMTP** etc.

The Pro-Ring2se self-recovery scheme can recover Ring network in less than 20ms with single ring up to 50 switches with one step setup. Lantech IES-2008B builds all the important management features required in large network like DHCP Client/Server, 802.1X authentication, IGMP Query / Snooping and source only for reverse multicast flow, and advanced QoS. It also supports Ping commands via Web to detect whether a specific device is still connected for easy trouble-shooting.

The IES-2008B has the relay contact that is able to connect with alarm system and send Email and SNMP trap alert in case of power or port failure. It also has the built-in factory reset button and watchdog design can restore all setting back to factory default and automatically reboot the switch when CPU loading is find dead.

The IES-2008B is designed to meet with critical network environment with IP 30 enclosure and test under extensive Industrial EMI and Safety standards. With ATEX Directive 94/9/EC approval, the IES-2008B-ATEX can be implemented in hazardous or explosive condition without accelerating the damage. It’s the best choice for inflammable environment where the liquid, gas and vapor etc might present the hazardous condition which generally to be find in mining, oil & gas, chemical, processing automation areas. It’s also suitable for surveillance, factory automation, transportation, telecom / ISP outside terminal, heavy industrial factory and other factory assembly lines.

The Lantech IES-2008B is the best to be used in municipal, city surveillance, automation, transportation, mining, heavy Industrial factory and other factory assembly lines where needs reliable and robust network. The -E / -ATEX model can be used in extreme environments with an operating temperature range of -40°C to 75°C.
