SEL-2742
Ethernet Switch
The SEL-2742 is a 12-port DIN-rail- or surface-mounted software-defined networking (SDN) switch for industrial environments. The SEL-2742 combines with the SEL-5056 Network Management System (NMS) to improve LAN cybersecurity with a deny-by-default, zero-trust approach to network traffic forwarding. SDN streamlines network management, change control, and data collection for cybersecurity audits. The SEL-2742 is designed and built for operation in harsh environments, meeting IEEE 1613 requirements. The SEL-2742 operates in –40 to +85°C (–40 to +185°F), and dual power supply connections provide connectivity to primary and backup power sources. Software: SEL-5056 Network Management System (NMS)

Create Stronger Network Security
Control exactly what is allowed on your network with the deny-by-default architecture of the SEL-2742. SEL SDN uses four layers of matching rules to check every packet entering switches. Only packets matching the user-configured criteria are forwarded. SDN also makes systems more cybersecure by eliminating attack-prone networking features, like MAC tables, the Rapid Spanning Tree Protocol (RSTP), multicast, and broadcast.
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 faster than those achieved with traditional networking technology. And with no blocked ports for RSTP, all of the SEL-2742 ports are useable for communications flows.
Streamline NERC CIP Data Collection
Use the SEL-2742 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-2742 switches.
Programmatically Test and Validate Your Network
Reduce deployment timelines and eliminate errors by using the SEL-5056 to programmatically configure the network implementation and validate all configurations and contingencies prior to commissioning.
Synchronize Time Over the LAN With Accuracy
The SEL-2742 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.
