2-48 www. m oxa. com Introduction to IEC 61850-3 Ethernet Switches 2 Industry-Specific Ethernet Switches > Industry-Specific Ethernet Switches PT-7728 Series The PowerTrans PT-7728 is designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613), and railway applications (EN 50121-4), and also features critical packet prioritization (GOOSE, SMVs, and PTP) and a built-in MMS server. The PT-7728’s Gigabit and Fast Ethernet backbone, redundant ring, and 24 VDC, 48 VDC, or 110/220 VDC/VAC dual isolated redundant power • Built-in MMS server for integration with power SCADA systems • Switch data modeling based on the IEC 61850-90-4 standard • IPv6 Ready logo awarded (IPv6 Logo Committee certified) • Software-based IEEE 1588v2 PTP (Precision Time Protocol) for time synchronization of networks • VLAN Unaware: Supports priority-tagged frames to be received by specific IEDs • DHCP Option 82 for IP address assignment with different policies • EtherNet/IP and Modbus/TCP industrial Ethernet protocols supported • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), RSTP/STP, and MSTP for network redundancy IEC 61850-3 24+4G-port Layer 2 Gigabit modular managed rackmount Ethernet switches supplies increase the reliability of your communications and save on cabling/wiring costs. The modular design of the PT-7728 also makes network planning easy, and allows greater flexibility by letting you install up to 4 Gigabit ports and 24 Fast Ethernet ports. Along with the optional front or rear wiring, these features together make the PT-7728 suitable for a variety of industrial applications. • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols • Supports advanced VLAN capability with Q-in-Q tagging • IEEE 802.3ad, LACP for optimum bandwidth utilization • Bandwidth management prevents unpredictable network status • Multi-port mirroring for online debugging • Automatic warning by exception through email, relay output • RMON for efficient network monitoring and proactive capability • Automatic recovery of connected device’s IP addresses • Line-swap fast recovery • Configurable by web browser, Telnet/serial console, CLI, Windows utility, and ABC-01 automatic backup configurator General Features and Benefits Introduction • User passwords with multiple levels of security protect against unauthorized configuration • SSH/HTTPS is used to encrypt passwords and data • Lock switch ports with 802.1X port-based network access control so that only authorized clients can access the port • Disable one or more ports to block network traffic • 802.1Q VLAN allows you to logically partition traffic transmitted between selected switch ports • Secure switch ports so that only specific devices and/or MAC addresses can access the ports • RADIUS/TACACS+ allows you to manage passwords from a central location • SNMPv3 provides encrypted authentication and access security Slot 1 Slot 2 Slot 3 Slot 4 Modular Rackmount Ethernet Switch System, PT-7728 Specifications Cybersecurity Features › ›IEC 61850-3, IEEE 1613 (power substations), and EN 50121-4 (railway applications) compliant › ›Built-in MMS server based on IEC 61850-90-4 switch data modeling for power SCADA › ›Complies with a portion of EN 50155 specifications › ›Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), RSTP/STP, and MSTP for network redundancy › ›VLAN Unaware: Supports priority-tagged frames to be received by specific IEDs › ›Up to 12 ports with M12 connectors › ›Isolated redundant power supplies with universal 24 VDC, 48 VDC, or 110/220 VDC/VAC power supply range › ›-40 to 85°C operating temperature range Technology Standards: IEEE 802.3 for 10BaseT IEEE 802.3u for 100BaseT(X) and 100BaseFX IEEE 802.3ab for 1000BaseT(X) IEEE 802.3z for 1000BaseX IEEE 802.3x for Flow Control
