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.
