The PT-7528 series supports Moxa’s Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed. The PT-7528 series also features critical packet prioritization (GOOSE, SMVs, and PTP), a built-in MMS server, and a configuration wizard designed specifically for substation automation. With Gigabit • Built-in MMS server for integration with power SCADA systems • Switch data modeling based on the IEC 61850-90-4 standard • Fiber Check™ provides monitoring and diagnosis functions on MST/MSC/SSC/SFP fiber ports • Noise Guard™ provides a high level of EMC immunity for critical applications, exceeding IEEE 1613 Class 2 • 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 IEC 61850-3 28-port Layer 2 managed rackmount Ethernet switches Ethernet, redundant ring, and 110/220 VDC/VAC isolated redundant power supplies, the PT-7528 series further increases the reliability of your communications and saves cabling/wiring costs. The wide range of PT-7528 models available support multiple types of port configuration, with up to 28 copper or 24 fiber ports, and with up to 4 Gigabit ports. Taken together, these features allow greater flexibility, making the PT-7528 suitable for a variety of industrial applications. switches), RSTP/STP, and MSTP for network redundancy • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols • IEEE 802.3ad, LACP for optimum bandwidth utilization • Bandwidth management prevents unpredictable network status • Multiport 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-02 automatic backup configurator General Features and Benefits Introduction • User passwords with multiple levels of security to 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 Cybersecurity Features › ›IEC 61850-3, IEEE 1613 (power substations) compliant › ›Built-in MMS server based on IEC 61850-90-4 switch data modeling for Power SCADA › ›Noise Guard™ wire speed zero packet loss technology › ›Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), RSTP/STP, and MSTP for network redundancy › ›Isolated redundant power supplies with universal 24/48 VDC or 110/220 VDC/VAC power supply range › ›-40 to 85°C operating temperature range
