Rebooting the UBox into Safe Mode Using the Reset Button
If you have made an unwanted change to the UBox settings and can no longer
access the UBox, you can boot it into a “safe mode.” In this mode, the UBox reboots
using default settings (e.g., multi-user connect mode or default IP mode) and allows
you to view and edit the settings.
To boot into safe mode:
1. Press and hold the reset button until the lights turn off (this takes 3 or more
seconds). It takes approximately 15 seconds to complete the reset.
2. In the Lantronix UBox application, make sure that your Local UDP Port is set to
10010.
3. Once you have verified the port, check the Lantronix UBox application to see
whether your UBox displays.
4. If it does not display, check the SYSTEM status LEDs to determine the UBox’s
network condition.
