EL326 Layer 3 Industrial Ethernet Switch

industrial_networking_el326_smExtremeLine Managed Industrial Connectivity

The Sixnet EL326 layer 3 Industrial ethernet switch is a Layer 3 rack-mount managed industrial Ethernet switch with advanced capabilities, designed to meet the performance requirements of power substations, traffic control, railway and other mission-critical networks. Combining the high availability and security of an enterprise-class switch with rugged packaging and protected circuitry, the EL326 easily handles even the most bandwidth intensive applications.


Deployment flexibility is guaranteed through Ethernet link speeds ranging from 10Mb/s to 10Gb/s. With 24 ports of Gigabit Ethernet – including four combo SFP ports that support either copper or fiber links – the EL326 industrial switch seamlessly scales to address growing network requirements. Optional 10 Gigabit Ethernet uplinks and dedicated stacking ports enable the stacking of up to eight industrial switches, providing the ability to add additional switch capacity and redundancy as required. This reduces initial infrastructure costs while providing longer term scalability.
