Maximized Ethernet Network Robustness—Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M and SEL-2730U Unmanaged 24-Port Ethernet Switch meet or exceed 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-2730M and SEL-2730U employ the most robust technology available for demanding applications.
Easy Network Commissioning—Easily install and configure the SEL-2730M. 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 acSELerator QuickSet SEL-5030 Software. Use the configuration file for easy backups and restoration.
Flexible, Modular Design—Upgrade existing sites with 4 Gigabit Ethernet copper ports and 16 10/100 Mbps copper Ethernet ports, built as 4-port modules. Each of the 10/100 Mbps copper port modules can be ordered with single- or multimode fiber-optic ports to meet your network's unique requirements. In addition, you can add up to 4 fiber-optic Gigabit Ethernet ports via small form-factor pluggable (SFP) transceivers for a total of 24 ports.
Secure Network Management—Increase security with the SNMPv3 and HTTPS features on the SEL-2730M. 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.
Network Integrity Protection—Use a Bridge Port Data Unit (BPDU) guard in the SEL-2730M to prevent unauthorized network extensions. Provide central authentication with the Lightweight Directory Access Protocol (LDAP). Protect client saturation with rate limiting.
Network Topology Configuration—Use any of the available 4,094 VLANs for switch-to-switch connections with the SEL-2730M. Monitor VLAN configurations with easy-to-read graphics. Monitor the status through Syslog and the Simple Network Management Protocol (SNMP).
Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M meets or exceeds IEEE 1613 (Class 2) and passed KEMA testing to validate compliance to 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).
SEL is committed to providing superior reliability and quality in all of 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 service due to a single power source failure.
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 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 LDAP.
Flexible, Modular Design
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 SFP transceivers for a total of 24 ports.
Comprehensive security features, such as SNMPv3, HTTPS, and MAC security, ensure that only authorized users and devices have access to the network.
BPDU Guard prevents spurious BPDU packets from affecting the network. Port rate limiting helps prevent broadcast, multicast, or unicast Ethernet storms from disrupting network operations.
SEL builds all of its switches in U.S.-based manufacturing facilities using the same processes used to build its relays, and offer the same no-questions-asked, worldwide, ten-year product warranty for our networking equipment that they do for protection and automation equipment.
