SEL-2740M

Managed Ethernet Switch

The SEL-2740M is designed for the harsh conditions found in energy and industrial environments. The switch supports communications infrastructure built for engineering access, supervisory control and data acquisition (SCADA), and real-time data communications, while offering the same reliability found in SEL protective relays. The SEL-2740M meets or exceeds the IEEE 1613 (Class 2), IEC 61850-3, and IEC 60255 industry standards for vibration, electrical surges, fast transients, extreme temperatures, and electrostatic discharge for communications devices in electrical substations.

Maximized Ethernet Network Robustness—Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2740M meets or exceeds IEEE 1613 (Class 2) and IEC 61850-3 standards for communications devices in electric power substations.

Reliability in Harsh Environments—Connect to primary and backup power sources simultaneously with dual, hot-swappable power supplies. This ensures that there will not be a loss of service due to a single power source failure. The design minimizes the number of interface points on printed circuit boards (PCBs), resulting in greater reliability. With no fans or other moving parts, the SEL-2740M employs the most robust technology available for demanding applications.

Easy Network Commissioning—Easily install and configure the SEL-2740M. Setting up priority messaging via virtual local-area networks (VLANs) is simplified to ensure the transmission of IEC 61850 GOOSE messages and current differential traffic to intelligent electronic devices (IEDs) while segmenting protection, control, and automation traffic. Update settings either through a secure web interface or offline for later download to the switch.

Flexible, Modular Design—Accept a wide variety of network interface options with six network interface slots. Choose any six of the ordering options to create your perfect switch.

Secure Network Management—Increase security with the SNMPv3 and HTTPS features on the SEL-2740M. SNMPv3 provides secure network management and is interoperable with existing network management systems (NMS). An HTTPS web interface provides secure and intuitive switch management. Map configurable system and security events to the alarm contact for alarming through an external system, such as an existing SCADA network.

Precision Time Protocol—Use microsecond-accurate network timing for the most sensitive synchronous applications. The SEL-2740M supports IEEE 1588-2008 with the IEEE C37.238-2011 power profile.

Overview

image.img.altimage.img.alt

Tough
Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2740M meets or exceeds IEEE 1613 (Class 2) and IEC 61850-3 Class A standards for communications devices in electric power substations, with a specified temperature range of –40º to +85ºC (–40º to +185ºF).

Reliable
SEL is committed to providing superior reliability and quality in all of its products. The SEL-2740M is equipped with dual hot-swappable power supplies, allowing simultaneous connection to primary and backup power sources. This ensures no loss of service due to a single power source failure.

Easy to Use and Administer
The SEL-2740M is easy to install and configure. The web management interface has been engineered to emphasize ease of use for common tasks, such as setting up priority communications using VLANs. Settings can be configured online through the secure web interface or offline for later uploading to the switch. Access to the HTTPS web interface can be managed centrally via the Lightweight Directory Access Protocol (LDAP) or Remote Authentication Dial-In Service (RADIUS).

Flexible, Modular Design
The base model SEL-2740M has six modular slots that accept a wide range of network interface options. This allows you to build your perfect switch or just expand the interfaces when you need them.

Secure
Comprehensive security features, such as SNMPv3, HTTPS, and MAC security, ensure that only authorized users and devices have access to the network.

Robust
Bridge Protocol Data Unit (BPDU) Guard prevents spurious BPDU packets from affecting your network. Port rate limiting helps prevent broadcast, multicast, or unicast Ethernet storms from disrupting your network operations. Use rate limiting to protect ports and overall switch performance from packet saturation to improve the high-priority messages to make it through to their destination.

Dependable
SEL builds all of its switches in U.S.-based manufacturing facilities using the same processes used to build its relays, and offers the same no-questions-asked, worldwide, ten-year product warranty for our networking equipment that we do for protection and automation equipment.

Precision Time Protocol (PTP)
Support precise timing applications with the integrated PTP functionality, which meets IEEE 1588-2008 with an IEEE C37.238-2011 power profile.
