switch IES-2008B

8 10/100TX Industrial Managed Ethernet Switch

  • Pro-Ring2se for self-heal ring <20ms
  • Support Advanced SNMP including QoS, IGMP query & source only, CPU load monitoring
  • Watchdog Design and Factory Default Button
  • DNV Type Approved for Ships, Craft and Off-shore Platforms

The Lantech IES-2008B-DNV 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-DNV 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-DNV 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-DNV is designed to meet with critical network environment with IP 30 enclosure and test under extensive Industrial EMI and Safety standards. The Lantech IES-2008B-DNV meets with the most critical test criteria in DNV Type test directives consisting of MED (Marine Equipment Directive), EMC (Electromagnetic Compatibility Directive) and LVD (Low Voltage Directive) in which vibration, high voltage, compass safe distance, salt mist tests, humidity etc are conducted to ensure the switch sustaining the harsh on-board environments often founded in Ships, Crafts and Offshore platforms.

The Lantech IES-2008B-DNV 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. It can be used in extreme environments with an operating temperature range of -40°C to 75°C.
