The SEL-2740S is designed to perform reliably even in the toughest environmental conditions commonly found in electric and industrial applications. The SEL-2740S is specifically developed to support IEC 61850 network requirements with industry leading performance and cybersecurity. The operational technology (OT) software-defined networking (SDN) solution supports enterprise and OT requirements ranging from real-time control to process control systems (PCSs), distributed control systems (DCSs), and SCADA.
Create Stronger Network Security—Control exactly what is allowed on your network with the deny-by-default architecture and multilayer packet inspection at each hop with the SEL-2740S. OT SDN allows you to control what devices are allowed on your network and what conversations each device is allowed to have. Only packets matching the authorized conversations are forwarded; all others are dropped or forwarded to your intrusion detection system. OT SDN also makes systems more cybersecure by eliminating legacy, attack-prone networking features, like MAC tables, the Rapid Spanning Tree Protocol (RSTP), multicast, and broadcast.
Improve Failover Performance—OT SDN proactively traffic-engineers networks, bringing more precision and predictability to critical infrastructure networks and improving failover times to less than 100 μs, two orders of magnitude less than those achieved with legacy networking technology. And with no blocked ports for RSTP, all of the SEL-2740S ports are usable for communications flows.
Streamline NERC CIP Data Collection—Use the SEL-2740S to establish inline, nonbypassable security controls for ports and services. Use the SEL-2740S and SEL-5056 with the SEL Flow Auditor application to automate information collection and reporting of NERC CIP-007-6 R1.1 without dangerous scanning or expensive truck rolls, 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. 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 C37.238-2017 power system profile to ensure submicrosecond time synchronization of end devices.
