Introduction
The 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 and SMVs) 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 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.
Additional Features and Benefits
• Switch data modeling based on the IEC 61850-90-4 standard
• IEEE 1588v2 PTP (Precision Time Protocol) for time synchronization
of networks (PTP models only)
• 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
• 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 to prevent unpredictable network status
• Multi-port mirroring for online debugging
• Automatic warning by exception through email and relay output
• RMON for proactive and efficient network monitoring
• 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
Cybersecurity Features
• User passwords with multiple levels of security protect against
unauthorized configuration
• 802.1Q VLAN allows you to logically partition traffic transmitted
between selected switch ports
• 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
• Secure switch ports so that only specific devices and/or MAC
addresses can access the ports
• Disable one or more ports to block network traffic
• RADIUS/TACACS+ allows you to manage passwords from a central • SNMPv3 provides encrypted authentication and access security
