 The PathWay® Model 7339  CAT5E 10/100/1000BASE-T RJ45 A/B Automatic Fallback Switch with 10/100 Base-T LAN Telnet Access and GUI, allows the user the capability of sharing a single port interface device connected to the "COMMON" port among two other devices connected to the "A" and "B" ports with remote access functionality. Remote Control access can be accomplished using an Ethernet 10/100-Base-T connection and either Telnet commands or Graphical User Interface (GUI).   The Model 7339 is enclosed in a 1U, full rack size, all metal black chassis designed to provide EMI/RFI shielding and fit in a standard 19" rack.

When in Automatic Fallback Mode the unit monitors data activity on ports A and B.  If activity is lost on port A, the unit checks for data on Port B and in the presence of data, switches to position B.  The Model 7339 data switch will maintain its connection to port B until data activity is detected on port A, at which time the unit will automatically return to the A position.  If no data is present on either port A or on port B, the unit will stay in the A position and continue to monitor for data.  The user can override Automatic Fallback Operation from the front panel or GUI interface and force the unit to operate as an A/B switch.


  • Access User Interface via standard web browser.
  • Easy to use, simple point and click operation.
  • Remotely access to control or monitor the Model 7339 RJ45 A/B Auto Fallback Switch System.
  • Users can change the switch's IP address.
  • LAN access gives users across the LAN or over the internet access to control if the user Network is configured accordingly


To connect to the switch from a workstation or computer having access to the LAN that the Model 7339 LAN port is connected to, simply launch a standard web browser and type in the appropriate IP address.  The Java Applet will be automatically uploaded from the switch upon connection.  The environment requirement for the GUI is Java 1.7 and above.
