Industrial-grade solution for the most demanding environments.

Suitable for explosive gas and other physically demanding environments, such as manufacturing plants, oil refineries, and utilities.

Industrial-Grade Reliability

Maintenance-free reliability can provide years of uninterrupted service in a wide range of severe temperature and hazardous gas conditions.

Advanced Security and Traffic Control Features in a Hardened Switch

No switch vendor matches Extreme Networks for providing a secure infrastructure. This same functionality is now available in a fully industrialized switch.

Fully Managed Solution

The I-Series is securely SNMP-managed to allow control of the device by authorized users from anywhere on the network, while all events and traffic statistics are reported and tracked by the Extreme Networks Network Management Suite (NMS).

Easy Installation

Optional memory configuration card allows non-technical personnel to field-replace I-Series switches with a simple removal and reinsertion of a memory configuration card. The card carries a copy of the switch configuration and allows settings to be quickly transferred to another I-Series switch.

Demanding environments still require all of the control and flexibility of their office counterparts.

No compromises needed to have control, flexibility, and reliability.

Business alignment

• Supports a variety of network-attached devices such as Programmable Logic Controllers (PLCs), shop floor workstations, and security cameras
• DIN-mountable and rack-mountable for flexible installation
• Portable, non-volatile memory card enables quick configuration of new or replacement switches

Operational efficiency

• Operational tolerance for extreme temperatures (-40° C to 60° C) enables placement in uncontrolled temperature environments
• High-availability design and simple field maintenance minimizes technical support expense
