The QuickSwitch® Model 6303 Single Channel LC Duplex A/B/C Switch, Multimode with Telnet & GUI allows the user the capability of sharing a single port LC Duplex interface device, connected to the "COMMON" port, among three other devices, connected to the "A", "B", and "C" ports. The QuickSwitch 6303 is enclosed in a 1U, full rack size, all metal black chassis designed to fit in a standard 19" rack.

Remote access can be accomplished using an Ethernet 10/100Base-T connection via Telnet Commands or Graphical User Interface.

Users can then monitor status, lockout front panel pushbutton control, and control switch position.

Option: Wide Range Power Supply:(Cat No. 517277) CE, RoHS, and UL listed table mount power module, 100VAC-240VAC, 50-60Hz for use in place of the standard power module that is included with the unit. Has IEC 60320 C14 inlet. Ideal for international applications.


To connect to the switch from a workstation or computer having access to the LAN that the QuickSwitch® Model 6303 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.

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 the 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 Lantronix’s website.

Changing Position and Lockout Status: 

To change the switch position of a channel, click on the radio button “A”, “B”, or “C” as desired.  Locking and unlocking the front panel pushbuttons can be done by clicking on the “Locked” or “Unlocked” radio buttons via the GUI (Graphical User Interface).  See Figure 2

Querying The Status of QuickSwitch® 6303 via the Graphical User Interface 

Once connected, the GUI will stay up-to-date on the present position and status of the unit. 

Any changes that are made outside of the GUI, such as by pushbutton, will be reflected in the GUI.  Auto-send of updates should be enabled, in order to reflect the most accurate status updates such as pushbuttons. These changes will cause the radio buttons of the GUI to automatically change to show the new status.  The GUI will report the source of the most recent change in the bottom left of the panel See Figure 3.
