SEL Ethernet Switch
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.
Our specific deny-by-default architecture of the SEL-2740S means nothing gets into your network without your approval. Every layer of every packet is inspected to see if it matches the set of rules you configured. If there’s a mismatch, the packet can be immediately dropped or forwarded to an intrusion detection system for in-depth analysis. Plus, you have the option to change these rules at any time. With this level of control, your network security becomes a certainty.
You know your network best; you know how it should operate. That’s why the SEL-2740S with SDN technology is so revolutionary—because it puts the design control in your hands. You define and engineer every packet flow, every failure response, every decision. That means you can guarantee the preservation of critical data. Want the validation? The SEL-5056 Software-Defined Network Flow Controller makes it easy to programmatically test every contingency before going live, so you know it will work.
