Schweitzer Engineering Laboratories, Inc. SEL-2730M Data Sheet

Reliable Ethernet Communication for Substation and Plant Networks

Major Features and Benefits

The SEL-2730M Managed Ethernet Switch is designed for the harsh environments commonly found in the energy and utility industries. The SEL-2730M supports communications infrastructures built for engineering access, supervisory control and data acquisition (SCADA), and real-time data communication and offers the same reliability found in SEL protective relays.

➤ Reliable. Increase availability with the SEL-2730M, which is designed, built, and tested to function in harsh environments such as substations. Optional hot-swappable, dual power supplies allow connectiv-ity to primary and backup power sources.

➤ Flexible. Maximize flexibility by using SEL-2730M ordering options to meet different network con-figurations. Order the SEL-2730M with Ethernet ports in combinations of copper, single-mode fiber, and multimode fiber. Add even more flexibility by using the four small form-factor pluggable (SFP) modules to change port configurations when network designs change.

➤ Ease-of-Use. Simplify configuration and maintenance with a secure web interface that allows conve-nient setup and management. Configure settings offline by using ACSELERATOR QuickSet® SEL-5030 Software or through an exported settings file that can be imported later on the switch.

➤ Virtual Local Area Networks (VLANs). Segregate traffic and improve network organization and per-formance. Take advantage of IEEE 802.1Q-2005 VLANs to separate IEC 61850 GOOSE messages from other traffic with as many as 4094 LANs.

➤ Traffic Prioritization. Support critical substation messaging by classifying and prioritizing traffic into one of four priority levels through VLAN-based 802.1Q-2005 Class of Service (CoS) and IP-based DiffServ Differentiated Services Code Points (DSCP).

➤ Rapid Spanning Tree Protocol (RSTP). Use IEEE 802.1D-2004 Rapid Spanning Tree Protocol (RSTP) to speed network recovery and convergence after a topology change caused by a link or device failure.

➤ Bridge Protocol Data Unit (BPDU) Guard. Improve network robustness by enabling BPDU Guard to disable a port when unexpected BPDUs are received.

➤ Port Rate Limiting. Prevent network storms from disabling your network by configuring maximum allowed rates for ingress (incoming) or egress (outgoing) traffic on each port.

➤ Multicast MAC Filtering. Filter multicast traffic to reduce network load on end devices.

➤ Port-Based MAC Security. Use port-based MAC security to limit network access to authorized devices.

SEL-2730M 24-Port Managed Ethernet Switch

SEL-2730M Data Sheet Schweitzer Engineering Laboratories, Inc.

➤ Time Synchronization. Synchronize time by using network time protocol (NTP). Time-align events and user activity across your system.

➤ Syslog. Log events for speedy alerts, consistency, compatibility, and centralized collection. Use the switch to forward Syslog system and security logs to as many as three central servers.

➤ Dynamic Host Configuration Protocol (DHCP). Easily connect a laptop computer during initial setup by using settings that enable the front-panel 10/100BASE-T Ethernet port to function as a DHCP server.

➤ Security and Monitoring. Increase security by taking advantage of SNMPv3 and HTTPS features.

SNMPv3 provides secure network management and is interoperable with existing network manage-ment systems (NMS). An HTTPS web interface provides secure and intuitive switch management.

Map system and security events to configurable alarm contact behavior for alarming through an exter-nal system, such as an existing SCADA network.

➤ Port Mirroring. Monitor ingress and egress traffic for viewing network statistics and performing trou-bleshooting.

➤ Port Monitoring. Monitor port heath for link flap and frame check sequence cyclic redundancy check (CRC) errors.

➤ User-Based Accounts. Provide user accountability and separate authorization levels for configuration and maintenance. Use LDAP or RADIUS with two-factor authentication for centralized user authentication.

➤ Port Configuration. Use per port configuration of settings such as speed, duplex, and auto-negotia-tion, which facilitates connection with other devices.

Functional Overview

Figure 1 Functional Diagram

The base-model SEL-2730M has four Gigabit Ethernet copper ports and sixteen 10/100 Mbps copper Ethernet ports, built as 4-port modules. You can order each of the 10/100 Mbps copper port modules as single- or multi-mode 100 Mbps fiber-optic ports to meet the unique requirements of your network. You can also add as many as four fiber-optic Gigabit Ethernet ports via SFP mod-ules, for a total of 24 ports.

➤ Four SFP ports. Ports 1–4 are compatible with the single- or multimode fiber SFP modules orderable from SEL.

➤ Four Gigabit Ethernet ports. Ports 5–8 support 10/100/1000 Mbps copper Gigabit Ethernet.

➤ Sixteen Fast Ethernet ports. Ports 9–24 can be ordered in combinations of 2-port groups of either copper or fiber.

➤ Redundant, hot-swappable power supplies.

Optional redundant power supplies provide failover protection. Connect a separate power source to each power supply. If one source fails, the other continues to keep the switch operational. The power supply has an estimated MTBF of 3000 years.

➤ Reversible mounting. The SEL-2730M comes with reversible mounting ears to support both front- and rear-panel installations.

Configurable in Groups of Two:

• 10/100BASE-T

• 100BASE-FX

• 100BASE-LX10

Status and Activity LEDs Local Management Port

SEL manufactures the SEL-2730M with the same high standards as those for SEL protective relays and backs it with the same 10-year worldwide warranty.

The SEL-2730M meets or exceeds the IEEE 1613 Class 1, IEC 61850-3, and IEC 60255 industry standards for communications devices in electrical substations for vibration, electrical surges, fast transients, extreme tem-peratures, and electrostatic discharge.
