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
