SEL-2740S

Software-Defined Network Switch

The SEL-2740S is the industry’s first field-hardened software-defined networking (SDN)-enabled switch and is designed to improve Ethernet cybersecurity and performance for operational technology (OT) applications. The SEL-2740S and the SEL-5056 Software-Defined Network Flow Controller give you path- and packet-level control of your communications flows, which eliminates common cybersecurity vulnerabilities in traditional LANs and improves failover performance to less than 100 μs. SEL SDN also makes it easy to more precisely manage large amounts of network traffic, making it the perfect solution for anyone transitioning to IEC 61850. The SEL-2740S is designed for the harsh environments commonly found in electric utility substations and industrial plants.

Create Stronger Network Security—Control exactly what is allowed on your network with the deny-by-default architecture of the SEL-2740S. The flow table configuration allows matching rules on fields in Layer 1 through Layer 4 of the packet. This gives the system owner control of what is allowed on the network at every layer of the network. Only configured flows are forwarded. These rules can be preconfigured or dynamically set from the SEL-5056. SDN makes systems more cybersecure by eliminating attack-prone networking features, like MAC tables, the Rapid Spanning Tree Protocol (RSTP), and cast types.

Improve Failover Performance—SDN allows you to predefine every network path, bringing more precision to critical infrastructure networks and improving failover times to less than 100 μs, two orders of magnitude less than those achieved with traditional networking technology. And with no blocked ports for RSTP, all of the SEL-2740S ports are useable for communications flows.

Streamline NERC CIP Data Collection—Use the SEL-2740S and SEL-5056 with the SEL Flow Auditor application to automate reporting of NERC CIP-007-6 R1.1, which addresses system security management for open ports and services on cyber assets.

Manage Network Scalability and Change Management—Use the SEL-5056 to manage all network changes without affecting existing services and applications. All network additions and changes can be configured centrally and pushed out to configure the network of SEL-2740S switches.

Programmatically Test and Validate Your Network—Reduce deployment timelines and eliminate errors by using the SEL-5056 to programmatically test the network implementation and validate all configurations and contingencies prior to commissioning.

Synchronize Time Over the LAN With Accuracy—The SEL-2740S acts as a transparent Precision Time Protocol (PTP) clock, supporting the IEEE C37.238 power system profile to ensure submicrosecond time synchronization of end devices.
