The breakthrough software-defined networking (SDN) technology in the SEL-2740S Software-Defined Network Switch solves the inherent limitations of Ethernet networks. Now, every network path is defined by you; you control how your system responds to network failures. You decide who and what applications are and are not allowed. Instead of programming every device, program one. Instead of waiting on discovery or convergence times, predefine every primary and failover path for the most recoverable Ethernet network possible.
Mission-critical processes demand mission-critical performance. The SEL-2740S fails over in less than 100 μs. Because of our innovative approach to SDN technology, you get the proactive advantage of engineering all primary and failover circuit paths prior to commissioning. No more waiting for discovery or convergence times—your network already knows the next path.
Through the SEL-5056 Flow Controller, your entire network is managed from one PC. If it seems like you’re at the center of everything, it’s because you are. Look into every SEL-2740S in your substations; monitor their status, health, and communications flows; and identify and mitigate vulnerabilities. The network visibility and intelligence are now centralized with you.
The SEL SDN starter kit includes:
Four SEL-2740S Switches
One SEL-3355 Computer with SEL-5056 Flow Controller Software
One 100-switch license for SEL-5056
One SEL-2726U Switch
