UTILIZING THE USER FRIENDLY REMOTE GRAPHICAL USER INTERFACE SOFTWARE
To connect to the switch from a workstation or computer having access to the LAN that the Model 7748 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.

10/100Base-T LAN SETUP
Network Setup

The switch is configured from the factory to use DHCP to automatically get its IP address from a DHCP server on the local area network when connected to the network and powered up. Therefore, a DHCP server is needed on the local area network for the initial configuration.  After that, the switch can be configured to use a static IP address. To find the IP address of a switch that it has gotten from the DHCP server, or to reconfigure the IP Address of the switch, use Lantronix® DeviceInstaller application.

Getting DeviceInstaller

DeviceInstaller requires Microsoft's .NET Framework version 4.0 or higher.  If the .NET Framework is not already installed, it must first be installed. The .NET Framework can be downloaded from Microsoft's website, either as a web install, or as a standalone installation.  The latest version of DeviceInstaller can be downloaded from the Lantronix's website.

 SOFTWARE FEATURES:

  • Access User Interface via standard web browser.
  • Easy to use, simple point and click operation.
  • Remotely access to control or monitor the Model 7748.
  •  Users can change switch's IP address.
  • LAN access gives users across the LAN or over the Internet access to control if user network is configured accordingly.
