System Version Information
To determine the hardware capability of your W311/321/341, and what kind of software functions
are supported, check the version numbers of your W311/321/341’s hardware, kernel, and user file
system. Contact Moxa to determine the hardware version. You will need the Production S/N

To check the kernel version, type:
#kversion

NOTE
The kernel version number is for the factory default configuration. You may download the latest

Upgrading the Firmware
The W311/321/341’s bios, kernel, and root file system are combined into one firmware file, which
can be downloaded from Moxa’s website (
www.moxa.com ). The name of the file has the form
w341-x.x.x.frm , with “x.x.x” indicating the firmware version. To upgrade the firmware,
download the firmware file to a PC, and then transfer the file to the W311/321/341 using a console
port or Telnet console connection.
ATTENTION
Upgrading the firmware will erase all data on the Flash ROM
If you are using the ramdisk to store code for your applications, beware that updating the
firmware will erase all of the data on the Flash ROM. You should back up your application files
and data before updating the firmware.
