Connecting Peripherals
USB Mass Storage
The UC-8410/8416/8418 supports PNP (plug-n-play), and hot pluggability for connecting USB
mass storage devices. The UC-8410/8416/8418 has a built-in auto mount utility that eases the
mount procedure. The connected USB mass storage device will be mounted automatically. You
can check the location of the USB disk by mount command. The UC-8410/8416/8418 will be
un-mounted automatically with umount when the device is disconnected.
ATTENTION
Remember to type the
#sync command before you disconnect the USB mass storage device. If
you don’t issue the command, you may lose some data.
Remember to exit the mount directory when you disconnect the USB mass storage device. If you
stay in mount directory, the auto un-mount process will fail. If that happens, type #umount
mount directory to un-mount the USB device manually. For example, type #umount /mnt/sdc.
The UC-8410/8416/8418 only supports certain types of flash disk USB Mass Storage devices.

Moxa: ~# mkdir /home/sda
Moxa: ~# mount -t ext2 /dev/sda1 /home/sda
You should umount the CF mass storage before you remove the CF card.
Moxa: ~# umount /home/sda
