Introduction

The PT-7828 switches are high-performance Layer 3 Ethernet switches that support Layer 3 routing functionality to facilitate the deployment of applications across networks. The PT-7828 switches are also designed to meet the strict demands of power substation automation systems (IEC 61850-3, IEEE 1613), and railway applications (EN 50121-4). The PT-7828 Series also features critical packet prioritization (GOOSE, SMVs, and PTP).

The PT-7828’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 and wiring costs. The modular design of the PT-7828 makes network planning easy, and allows greater flexibility by letting you install up to 4 Gigabit ports and 24 Fast Ethernet ports. Optional front or rear wiring makes the PT-7828 switches suitable for a variety of applications.

Additional Features and Benefits

  • Layer 3 switching functionality to divide a large network into hierarchical subnets and allow data and information to communicate across networks

  • Command line interface (CLI) for quickly configuring major managed functions

  • DHCP Option 82 for IP address assignment with different policies

  • EtherNet/IP and Modbus TCP industrial Ethernet protocols supported

  • Configurable by web browser, Telnet/serial console, CLI Windows utility, and ABC-01 automatic backup configurator

  • Supports multicast routing protocols PIM-DM/DVMRP

  • Supports advanced VLAN capability with Q-in-Q tagging

  • IGMP snooping and GMRP for filtering multicast traffic from industrial Ethernet protocols

  • 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

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
