Upgrading the Root File System & User Directory
The EM-1240-LX uses JFFS2 for root file system and user directory. By default, the root file
system is pre-set to READ only. The EM-1240-LX provides a read/write user’s directory in the
JFFS2 file system. By using this user’s directory, the system configuration file and user’s program
can be stored on this disk.
Search the EM-1240-LX’s CD-ROM for the latest user directory file, or download the file from
www.moxa.com. The format is em1240-1.x.dsk. You must download this file to a PC first, and
then use Console Terminal or Telnet Console to copy the file to the EM-1240-LX.
You can save this file to the EM-1240-LX’s RAM disk, and then upgrade the user directory. The
following is a step-by-step example.
To enable the RAM disk, use the following command.
/>upramdisk
/>cd ramdisk
Use the built-in FTP client to download the em1240-1.x.dsk file from the PC.
