SEL SEL-2742 Ethernet Switch

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.

Validation of all configurations and contingencies prior to commissioning

Operate in tough conditions.

IEEE 1613 compliance and a –40° to +85°C (–40° to +185°F) operating range

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.
