Industry-specific Ethernet Switches

The PowerTrans PT-G7509 is equipped with 9 combo Gigabit Ethernet 
ports, making it ideal for upgrading an existing network to Gigabit speeds 
and building a new full Gigabit backbone. The PT-G7509 is designed to 
meet the demands of power substation automation systems (IEC 61850-3, 
IEEE 1613). Gigabit transmission increases bandwidth to provide higher 

performance and transfer large amounts of video, voice, and data across 
a network quickly. The redundant Ethernet Turbo Ring, Turbo Chain, and 
RSTP/STP/MSTP (IEEE 802.1w/D/s) functions increase system reliability 
and the availability of your network backbone. The choice of either front or 
rear wiring makes the PT-G7509 suitable for different types of application.

•  Command line interface (CLI) for quickly configuring major 

managed functions

•  IPv6 Ready logo awarded (IPv6 Logo Committee certified) 
•  Software-based IEEE 1588 PTP V2 (Precision Time Protocol) for 

precise time synchronization of networks 

•  VLAN Unaware: Supports priority-tagged frames to be received by 

specific devices

•  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 < 50 ms @ 250 

switches), RSTP/STP, and MSTP 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 
•  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

•  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
