Loading Factory Defaults
To load the system’s factory default settings, press the reset-to-default button for at least 5 seconds.
Doing so will destroy all of the files in the /home and /etc directories. While holding the button for
the first 5 seconds, the ready LED will blink once each second. After holding the button
continuously for more than 5 seconds, the ready LED will switch off, indicating that the factory
defaults have been loaded.
Backing Up the User File System
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. After backing up the file system, use FTP to transfer the file usrfs-backup to your PC.

Deploying the User File System to Additional UC-7400-LX Plus Units
For some applications, you may need to ghost one UC-7400-LX Plus user file system to other
UC-7400-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-7400-LX Plus units.
#upramdisk
#cd /mnt/ramdisk
#upfirm usrfs-backup
