Loading Factory Defaults
To load the the factory default settings, you must press the reset-to-default button for more than 5
seconds. All files in the /home & /etc directories will be destroyed. Note that while pressing the
reset-to-default button, the Ready LED will blink once every second for the first 5 seconds. The
Ready LED will turn off after 5 seconds, and the factory defaults will be loaded.
Backing Up the User Directory
1. Create a backup file. First type the following command to enable the RAM disk:
#upramdisk
Next, use the file system backup utility provided by Moxa:
#backupuf /mnt/ramdisk/usrfs-backup
2. Once the file system is backed up, use FTP to transfer the file usrfs-backup to your PC.

Deploying the User Directory to Additional UC-7112-LX Plus Units
For some applications, you may need to ghost one UC-7112-LX Plus user file system to other
UC-7112-LX Plus units. Back up the user file system to a PC (refer to the previous subsection,
Backing Up the User File System, for instructions), and then type the following commands to copy
the backup to additional UC-7112-LX Plus units.
#upramdisk
#cd /mnt/ramdisk
