Industry-specific Ethernet Switches

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 v2 technology to fulfill precision time 
synchronization requirements for protection and control applications. 
These Ethernet switches guarantee time-stamping accuracy within 1 μs 

•  IPv6 Ready logo awarded (IPv6 Logo Committee certified) 
•  VLAN Unaware: Supports priority-tagged frames to be received by 

specific IEDs

•  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 

•  IGMP snooping and GMRP for filtering multicast traffic from 

industrial Ethernet protocols 

•  IEEE 1588 PTP V2 (Precision Time Protocol) with hardware time 

stamping for precise time synchronization of networks 

•  Support for both IEEE 1588 Boundary Clock and Transparent Clock

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.

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

•  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)

•  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

•  Radius/TACACS+ allows you to manage passwords from a central 

location

•  SNMPv3 provides encrypted authentication and access security
