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

• Line-swap fast recovery

• Configurable by web browser, Telnet/serial console, CLI, Windows

utility, and ABC-01 automatic backup configurator

• 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

Cybersecurity Features

• 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

• RADIUS/TACACS+ allows you to manage passwords from a central

location

• 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

• Disable one or more ports to block network traffic

• SNMPv3 provides encrypted authentication and access security
