SEL SEL-2741 Ethernet Switch

SEL-2741

Ethernet Switch

The SEL-2741 is a versatile managed Ethernet switch that supports operational technology (OT) software-defined networking (SDN) and Rapid Spanning Tree Protocol (RSTP) networking technologies.

Optimized for OT environments, the SEL-2741 supports critical infrastructure applications including IEC 61850 networks, protection-class Ethernet networks, engineering access, SCADA, and process control systems.

It is designed for extended product lifecycles and high reliability, even in the toughest environmental conditions, and it is backed by our industry-leading ten-year warranty.

Build Your Perfect 24-Port Switch

Choose from copper or small form-factor pluggable (SFP) options on 24 1 Gbps and 100 Mbps ports. Mix and match port types in groups of four. The SEL-2741 offers flexible mounting options and wide-range dual power supplies. It supports both SEL and non-SEL fiber SFPs with a generous power budget.

Future-Proof Your System

Order the SEL-2741 with either RSTP-based or OT SDN-based control plane technology. With a simple firmware upgrade, you can field convert between RSTP and OT SDN.

Synchronize Time Over the LAN With Accuracy

The SEL-2741 is a transparent Precision Time Protocol (PTP) clock that supports the IEEE C37.238-2017 power system profile to ensure submicrosecond time synchronization of end devices.

Operate in Tough Environments

The SEL-2741 is designed without fans or other moving parts, increasing its operational lifetime. It is built and tested for reliable operation in extreme environments, meeting or exceeding IEEE 1613 (Class 1) and IEC 61850-3 standards for communications devices in electric power substations.

Tough

The SEL-2741 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

The SEL-2741 can be equipped with a single or dual power supply in high or low voltage. A dual power supply allows simultaneous connection to primary and backup power sources. This ensures that a single power source failure cannot result in loss of service.High-Bandwidth and Flexible Port Options

The SEL-2741 supports 24 100/1000 Mbps ports. All ports can be ordered with either copper or SFP cage options. Mix and match port types in groups of four to build your perfect switch. The SEL-2741 supports all SEL SFPs as well as third-party SFPs that operate at 100- or 1000BASE-T.Quality of Service

The SEL-2741 provides flexible traffic priority configuration management through four 8:4:2:1 weighted round robin (WRR) or strict priority queues.Time Synchronization

The SEL-2741 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 (ACTS).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-2741 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.
