html{display:none} SEL-2730M Managed 24-Port Ethernet Switch | Schweitzer Engineering Laboratories


Managed 24-Port Ethernet Switch

The SEL-2730M is designed to operate in harsh environments, like those found in electric utility substations and industrial plants. The switch provides Ethernet connectivity for SCADA, engineering access, and control, and it offers the same reliability found in SEL protective relays. The SEL-2730M meets or exceeds IEEE 1613 (Class 1), IEC 61850-3, and IEC 60255 industry standards for vibration, electrical surges, fast transients, extreme temperatures, and electrostatic discharge.

Maximized Ethernet Network Robustness—Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M meets or exceeds IEEE 1613 (Class 1) 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 employs the most robust technology available for demanding applications.

Easy Network Commissioning—Easily install and configure the SEL-2730M. Setting up priority messaging via VLANs is simplified to ensure the transmission of IEC 61850 GOOSE messages and current differential traffic to IEDs while segmenting protection, control, and automation traffic. You can update settings either through a secure web interface or acSELerator QuickSet SEL-5030 Software. Using the configuration file makes backups and restoration easy.

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 or Copper 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) or one- or two-factor authentication with Remote Authentication Dial-In User Service (RADIUS). 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).

      Hot-swappable, redundant power supplies



Designed, built, and tested for trouble-free operation in extreme conditions, the SEL-2730M meets or exceeds IEEE 1613 (Class 1) 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. The SEL-2730M also monitors ports for link flap, when an interface continuously alternates between up and down states, often due to a bad cable.

Easy to Use and Administer
The SEL-2730M is easy to install and configure. The autonegotiation function for 1000BASE-X fiber ports enables the switch to easily autoconnect to third-party devices in the network. The web management interface has been engineered to emphasize ease of use for common tasks, such as setting up priority communications using VLANs. Any selection of ports can be mirrored for integration with an Intrusion Detection System (IDS). 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 LDAP or RADIUS.

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. These modules can be ordered as 4 single-mode fiber-optic ports, 4 multimode fiber-optic ports, or 2 copper and 2 multimode fiber-optic ports (Ports 17–20 only). In addition, up to 4 fiber-optic or copper 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 worldwide, ten-year product warranty for our networking equipment that they do for protection and automation equipment.

Mounting Options
The SEL-2730M is available in a panel-mount, rack-mount, or surface-mount hardware package to suit your application needs.
