Upgrading the Kernel
The EM-1240-LX kernel is em1240-1.x..bin, which can be downloaded from www.moxa.com.
You must first download this file to your PC, 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 kernel. The
following is a step-by-step example.
To enable the RAM disk, use the following command:
/>upramdisk
After executing “upramdisk”, you may use “mount” to find out if the new ramdisk is successfully
created as shown.
You can navigate to the device node, using the following command:
/>cd ramdisk
Use the built-in FTP client to download the em1240-1.x.bin file from the PC.
/ramdisk>ftp <destination PC’s IP>
Login Name: xxxx
Login Password: xxxx
ftp> bin
ftp> get em1240-1.x.bin
Use the upkernel command to upgrade the kernel and root file system.
/ramdisk>upkernel em1240-1.x.bin
/ramdisk>reboot
