SEL-2740S Software-Defined Network (SDN) Switch Traffic-Engineered Ethernet Communication for Substation and Plant Networks Major Features and Benefits The SEL-2740S SDN Switch is a 20-port switch designed for the harsh environments common to critical infrastructure industries. The SEL-2740S is a deny-by-default network switch that enables full control of Ethernet traffic engineering. Traffic engineering provides you the ability to configure each communications flow path, configure flow match filters for approved forwarding, and pre-engineer failover conditions to design fault-tolerant networks. The result is greater performance, improved reliability, and more deterministic packet delivery. ➤ Reliability. Provides a robust design built and tested to function in harsh environments, meeting IEEE 1613 and IEC 61850-3 standards. Hotswappable, dual power supplies provide connectivity to primary and backup power sources. ➤ Fast Failover. Allows healing in microseconds with proactive traffic engineering for fault conditions. ➤ Modularity. Provides six hot-swappable modular interface slots and two power supply module slots. The SEL-2740S requires one alarm contact and flow coprocessor module, and it provides the installation option of as many as five Ethernet interface modules and two power supply modules. ➤ Redundancy. Provides strong, central management of all traffic flow circuits and backup circuits. Also provides operational statistics from the flow controller. ➤ Ease of Use. Supports quick commissioning and all network configuration programming through the SEL-5056 SDN Flow Controller. ➤ SDN Management. Supports OpenFlow® 1.3. ➤ Low-Latency Flow Setup. Allows quick establishment of flows through the use of lowlatency controller and table updates. ➤ Low-Latency Forwarding. Provides store- forward, low-latency forwarding. ➤ Large Flow Table Size. Supports small and large networks with a 4,096 flow entry capacity. ➤ Cybersecurity. Supports deny-by-default network access control and secure management of communication with OpenFlow 1.3 through Transport Layer Security (TLS) and the detailed central monitoring capability of the SEL-5056. ➤ Flexible Group and Action Bucket Support. Supports 256 groups and 30 action buckets per group, enabling flexible network design and traffic engineering. ➤ Packet Buffer Memory. Supports 87 packets at maximum transmission unit (MTU). ➤ Switching Capacity. Supports a 5.6 Gbps packet data rate and full duplex, nonblocking design. ➤ Forwarding Match Filters. Provides the user with control of all network forwarding through each hop by allowing configuration of match attributes for each flow on Layer 1, 2, 3, or 4 fields. ➤ Quality of Service (QoS). Provides traffic priority management through four 8:4:2:1 weighted round robin (WRR) priority queues. ➤ Network Time Protocol (NTP) Time Synchronization. Allows time synchronization through NTP and operation as an NTP client to time-align events and user activity across the system. ➤ X.509 Certificate. Supports secure communication between the switch and the flow controller, and manages keys through certificates. ➤ Backup and Restore. Generate backup images for incident recovery and quickly restore the system. Schweitzer Engineering Labora

The SEL-2740S is a standards-based, OpenFlow 1.3-compatible, 20-port switch that provides a rugged and versatile modular platform and supports build-to-suit switching solutions for applications in extreme environmental conditions. The SEL-2740S provides six communications module slots and two power supply slots. The main SEL-2740S chassis requires one alarm contact and flow coprocessor module in the first slot (Slot A) and then provides five optional slots for copper or fiber modules (Slots B-F), allowing users to construct the desired combination of communications interfaces. Users can...

Applications The SEL-2740S is ideally suited for use as an Ethernet switch for substation local-area networks (LANs), providing highly reliable, centrally managed, continuous, and easy-to-use status monitoring. The SEL-2740S is an SDN switch platform based on OpenFlow 1.3. It is specifically designed for systems that require exceptional reliability in rugged environments, relying on the revolutionary network advances of SDN technology. These advances include reduced complexity, improved performance, and centralized control and monitoring of entire networks. Combined with the SEL-5056, the...

Improve QoS and Maximize Operations Users can maximize asset use without port-blocking requirements such as those in RSTP. System owners can proactively engineer and test Ethernet circuits, predetermining exact primary and failover communications flow circuits. This results in more deterministic latency and less disruption during faults because the switch has Proactive Traffic Engineering of Path- and Packet-Level Flows and Redundancy Strong Cybersecurity and Audit Support An SDN provides strong network access control and a deny-by-default security model; packets are not forwarded until the...

Centrally Manage and Monitor Field networks can be managed and monitored as a single asset. The SEL-2740S works with the SEL-5056 to provide communications flow configuration and monitoring capabilities. This allows operators to monitor all flows and their attributes from a central location. No engineering access interface is necessary on the SEL-2740S; the SEL-5056 conveniently and centrally manages everything, greatly simplifying field deployment. In addition, the SEL-5056 provides backup and restore features for maintaining high reliability. Operators can take a snapshot of the system...
