Dual-network ports support10/100Base-TX copper and 100Base-FX fiber-optic connections with aredundant communication path for critical applications. Dual DC powerterminals enable use of redundant power sources. An embedded Web pageprovides configuration menus accessible with any Web browser toeliminate programming. The compact, stackable aluminum enclosureresists shock and vibration making it ideal for mounting directly onmachinery. Multiple units can stack in an eight-inch by seven-inch footprint. An openboard version is available for custom mounting. EtherStax are suitable for use in Class I, Division 2, Group A, B, C,and D locations.
