The Enterasys I-Series is an industrially hardened Ethernet switch especially designed to handle networking in physically demanding environments like manufacturing plants, oil refineries and utilities. The I-Series is in a form factor that uses convection cooling, DC power, and industrial-grade components that ensure continued uptime. The I-Series is unique for a hardened device because it incorporates far more advanced features than other products in this space. Enterasys' unique role-based architecture ensures that devices and users are enabled and confined to specific behavior on the network. In addition, Enterasys' advanced QoS provides deterministic control of the proprietary applications found in industrial environments. The I-Series provides the automation industry with a fully hardened switch without sacrificing high-end functionality.
