System Version Information

To determine the hardware capability of your UC-7420/7410, and what kind of software functions are supported, check the version numbers of your UC-7420/7410’s hardware, kernel, and user file system. Contact Moxa to determine the hardware version. You will need the Production S/N (Serial number), which is located on UC-7420/7410’s bottom label.

To check the kernel version, type:

#kversion

To check the user file system version, type:

#fsversion

192.168.3.127 – PuTTY

root@Moxa:~# kversion 1.4.3

root@Moxa:~# fsversion 1.4.3

root@Moxa:~#

NOTE The kernel version and user file system version numbers are the same for the factory default configuration, and if you download the latest firmware version from Moxa’s website and then upgrade UC-7420/7410’s hardware, the two version numbers will be the same.

However, to help users define the user file system, the kernel and user file system are separate, and hence could have different version numbers. For this reason, we provide two utilities, called kversion and fsversion, that allow you to check the version numbers of the kernel and file system, respectively.

System Image Backup

Upgrading the Firmware

UC-7420/7410’s bios, kernel, mini file system, and user 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 uc7400-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 UC-7420/7410 unit via a serial Console 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.
