SEL SEL-2743 Ethernet Switch

SEL-2743

Ethernet Switch

The SEL-2743 is a low-cost, DIN-rail-mounted managed Ethernet switch that supports either operational technology (OT) software-defined networking (SDN) or the Rapid Spanning Tree Protocol (RSTP).

With eight 10/100/1000BASE ports, the SEL-2743 is an industrial Ethernet switch optimized for applications that require a small footprint, such as substation cabinets, pad and pole installations, plant floors, and emergency services.

It is designed to operate reliably for 20 years in the toughest environmental conditions commonly found in electric utility and industrial applications, and it is backed by our industry-leading ten-year warranty.

Tough

The SEL-2743 is designed, built, and tested for reliable operation in extreme conditions. It meets or exceeds IEEE 1613 (Class 1) and IEC 61850-3 standards for communications devices in electric power substations and has a specified temperature range of –40º to +85ºC (–40º to +185ºF).

Reliable

Configure your SEL-2743 with an optional integrated dual power supply to ensure continuous operation through seamless failover protection. Choose between low voltage (24–48 V) or high voltage (48–250 V) for both single and dual power supply options.

PoE+

Order the SEL-2743 with two PoE+ Type 2 ports to make it easier to use devices for IT overlay applications, such as video and voice compliance with IEEE 802.3at-2009.

High-Bandwidth and Flexible Port Options

The SEL-2743 offers eight 10/100/1000BASE copper or 100/1000BASE SFP ports. Mix and match port types in groups of four to customize the switch to fit your exact needs. The SEL-2743 supports all SEL SFP transceivers as well as third-party SFP transceivers that operate at 100- or 1000BASE.

Quality of Service

The SEL-2743 provides flexible traffic priority configuration management through four 8:4:2:1 weighted round robin or strict priority queues.

Time Synchronization

The SEL-2743 offers PTP transparent clock support for the IEEE C37.238-2017 power profile and switch synchronization through the Network Time Protocol (NTP) or authenticated controller time synchronization.

Dependable

SEL manufactures all switches in the United States and offers a worldwide, ten-year product warranty.

RSTP

Easy to Use and Administer

The autonegotiation function enables the SEL-2743 to easily autoconnect to third-party devices in the network. The web management interface has been engineered to make common tasks easy to accomplish, such as setting up network segmentation using VLANs. Mirror any selection of ports for integration with an intrusion detection system. Configure settings online through the secure web interface or offline for later implementation. Access to the HTTPS web interface can be managed centrally via LDAP or RADIUS.

Secure

Comprehensive security features, such as SNMPv3. HTTPS, LDAP, Syslog, MAC security, and RADIUS, ensure that only authorized users have access to the switch. Detailed logs show you everyone who has accessed the switch and any action that was taken.

Stable

BPDU Guard prevents undesired network changes from affecting the network. Port rate limiting helps prevent broadcast, multicast, or unicast Ethernet storms from disrupting network operations. Port monitoring prevents link issues or cyclic dependencies from disrupting larger sections of the network.

RSTP

Simplify Network Commissioning—Installing and configuring the SEL-2743 is simple. You can easily set up priority messaging with VLANs, which prioritizes the transmission of IEC 61850 GOOSE messages and current differential traffic to devices while segmenting protection, control, and automation traffic. Update settings by either using a secure web interface or importing configuration files. Using configuration files makes backups and restoration easy.

Preserve Network Integrity—Use the Bridge Protocol Data Unit (BPDU) Guard in the SEL-2743 to prevent unauthorized network changes. Protect against client saturation with rate limiting.

Easily Segment and Monitor a Flexible Network Topology—Use any of the available 4.094 VLANs for switch-to-switch connections with the SEL-2743. Monitor VLAN configurations with easy-to-read graphics. Monitor the status through Syslog and the Simple Network Management Protocol (SNMP).

Quickly Integrate With an NMS—Thanks to extensive SNMP management information base support, the SEL-2743 integrates with leading NMSs to render network topology, RSTP states, VLAN memberships, and the host address and locations. Set traps to alert you when events happen on your network.
