Project Description

SEL-2730M Managed 24-Port Ethernet Switch

SEL-2730M Managed 24-Port Ethernet Switch

The SEL-2730M Managed 24-Port Ethernet Switch is designed for the harsh environments commonly found in the energy and utility industries. The switch supports communication 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-2730M 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 in communications devices in electrical substations.

Designed, built, and tested for trouble- free operation in extreme conditions, the SEL-2730M meets or exceeds IEEE 1613 (Class 2) and IEC 61850-3 standards for communications devices in electric power substations, with a specified temperature range of –40° to +85°C (–40° to +185°F).IEEE 1613 (Class 2) compliance compared to IEEE 1613 (Class 1) is very important because this means the SEL-2730M continues to operate without dropping any packets at the specified extreme environmental conditions.


SEL is committed to providing superior reliability and quality in all its products. The SEL-2730M is equipped with hot-swappable dual power supplies, allowing simultaneous connection to primary and backup power sources. This ensures no loss of communications due to a single power source failure.


Strong security features, such as SNMPv3, HTTPS, and MAC security, provide configurable access control lists and traffic management.


At SEL, we build all of our switches in U.S.-based manufacturing facilities using the same processes that we use to build our protective relays. And, we offer the same ten-year, worldwide, no-questions-asked warranty for our networking equipment that we do for protection and automation equipment.

Easy to Use and Administer

The SEL-2730M 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 virtual local-area networks (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).


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.

Flexible ordering options

The base-model SEL-2730M has 4 Gigabit Ethernet copper ports and 16 10/100 Mbps copper Ethernet ports, built as 4-port modules. Each of these 10/100 Mbps copper port modules can be ordered as single- or multimode fiber-optic ports to meet your network’s unique requirements. In addition, up to 4 fiber-optic Gigabit Ethernet ports can be added via small form-factor pluggable (SFP) transceivers, for a total of 24 ports.
