Industry-specific Ethernet Switches
PT-7728-PTP Series
The PowerTrans PT-7728-PTP switches are designed to meet the
demands of power substation automation systems (IEC 61850-3, IEEE
1613). The PT-7728-PTP’s redundant ring, and dual isolated redundant
power supplies increase the reliability of your communications and
save on cabling/wiring costs.
Moxa’s PT-7728-PTP IEC 61850-3 Fast Ethernet switches support
the latest version of IEEE 1588 technology (IEEE 1588v2 PTP) to
fulfill precision time synchronization requirements for protection and
control applications. These Ethernet switches guarantee time-stamping
• IPv6 Ready logo awarded (IPv6 Logo Committee certified)
• DHCP Option 82 for IP address assignment with different policies
• Modbus/TCP industrial Ethernet protocol supported
• Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250
switches), and RSTP/STP for network redundancy
• 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
• IEEE 1588v2 PTP (Precision Time Protocol) with hardware time
stamping for precise time synchronization of networks
• Support for both IEEE 1588 Boundary Clock and Transparent Clock
IEC 61850-3 14-port IEEE 1588v2 PTP rackmount Ethernet switches
accuracy within 1 μs for the IEC 61850 process layer. They can be
configured for 1588 v2 Master, Boundary Clock, and Transparent Clock
functionality.
The modular design of the PT-7728-PTP also makes network planning
easy, and allows greater flexibility by letting you install up to 14 IEEE
1588 Fast Ethernet ports or up to 24 non-IEEE 1588 Ethernet ports
and 4 Gigabit ports. Along with a choice of either front or rear wiring,
these features together make the PT-7728-PTP suitable for a variety of
industrial applications.
• 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
• Support for both End to End (2-step) and Peer to Peer (2-step)
modes in Transparent Clock
• High precision time accuracy (under 1 μs)
General Features and Benefits
IEEE 1588 PTP Features
Introduction
• 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
• 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
• SNMPv3 provides encrypted authentication and access security
