Industry-specific Ethernet Switches
PT-G7509 Series
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), and railway applications (EN50155/EN50121-4). Gigabit 
transmission increases bandwidth to provide higher performance and 
9 combo 10/100/1000BaseT(X) or 100/1000BaseSFP slot Gigabit 
 
ports
IEC 61850-3, IEEE 1613 (power substations), and EN50155/
 
EN50121-4 (railway applications) compliant
IEEE 1588 PTP for precise time synchronization of networks
 
Turbo Ring, Turbo Chain, and IEEE 802.1D-2004 RSTP/STP for 
 
Ethernet Redundancy
Isolated redundant power inputs with universal 24/48 VDC or 
 
110/220 VDC/VAC power supply range
-40 to 85°C operating temperature range
 
transfer large amounts of video, voice, and data across a network quickly. 
The redundant Ethernet Turbo Ring, Turbo Chain, and RSTP/STP (IEEE 
802.1w/D) 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.

General Features and Benefits
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 (available in Q1 Y2011)
SNMPv3 provides encrypted authentication and access security
