Introduction
The PowerTrans 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 5015/EN 50121-4).
General 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
• Software-based IEEE 1588v2 PTP (Precision Time Protocol) for
precise time synchronization of networks
• DHCP Option 82 for IP address assignment with different policies
• EtherNet/IP and Modbus/TCP industrial Ethernet protocols
supported
• Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250
switches), RSTP/STP, and MSTP for network redundancy
• Supports multicast routing protocols PIM-DM/DVMRP
The PT-7828’s Gigabit and Fast Ethernet backbone, redundant ring,
and 24/48 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.
• 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 prevents unpredictable network status
• Multi-port mirroring for online debugging
• Automatic warning by exception through email, relay output
• RMON for efficient network monitoring and proactive capability
• 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
Cyber-security 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
• Disable one or more ports to block network traffic
