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
• Supports advanced VLAN capability with Q-in-Q tagging
• IGMP snooping and GMRP for filtering multicast traffic from industrial
Ethernet protocols
• 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
• 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
• 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
