EM-1240-LX User’s Manual Configuring the EM-1240-LX

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

As illustrated below, after executing “upramdisk”, you may use “mount” to determine if the new

ramdisk was created successfully or not.

Use the following command to navigate to the device node:

/>cd ramdisk

Use the built-in FTP client to download the file em1240-1.x.bin from the PC.

/ramdisk>ftp <destination PC’s IP>

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
