SEL SEL-2744 Ethernet Switch

SEL-2744

Ethernet Switch

The SEL-2744 is a managed Ethernet switch built for high-bandwidth operational technology (OT) networks.

It supports either OT software-defined networking (SDN) or the Rapid Spanning Tree Protocol (RSTP) and is optimized for data-intensive applications, such as video streaming, IEC 61850-9-2 Sampled Values transmission, and data aggregation.

With two 1000BASE/10GBASE enhanced small form-factor pluggable (SFP+) ports and eight 10/100/1000BASE ports, the switch delivers a total bandwidth capacity of 28 Gbps.

Designed to operate reliably for 20 years in harsh environments, the SEL-2744 is an industrial Ethernet switch with a dual integrated, isolated power supply,

broad SFP transceiver compatibility, and a wide input voltage range—all backed by our ten-year warranty and lifetime technical support.

Tough

The SEL-2744 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-2744 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-2744 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-2744 includes two standard 1000BASE/10GBASE SFP+ ports and eight customizable 10/100/1000BASE copper or 100/1000BASE SFP ports. Mix and match the eight port types in groups of four to fit the switch to your exact needs. The SEL-2744 supports all SEL SFP transceivers as well as third-party SFP transceivers that operate at 100- or 1000BASE.

Quality of Service

The SEL-2744 provides flexible traffic priority configuration management through four 8:4:2:1 weighted round robin or strict priority queues.

Time Synchronization

The SEL-2744 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-2744 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.
