WML Sumo Thin Client User Guide
Firmware
Firmware upgrade image files are available from William Matthew Limited.
The firmware upgrade process requires a usb storage device. The firmware upgrade file is 56 MB in
size and must be placed directly (i.e. not within any sub-folders) on a usb storage device
of at least
128 MB
. The additional space is required to save temporary files used during the upgrade process.
Firmware upgrade files have a filename of the form st166sumo64-20060712_1000.img. The name
should not be changed after downloading; it should be stored on the USB drive with the original
name.
After inserting the USB drive containing the upgrade file into one of the USB ports on the Sumo,
run the Setup Manager and choose the “Firmware” tab. Click the “Refresh” button and the USB
drive will be scanned for a firmware image. If an image is found, the “Upgrade” button will be
enabled. Click “Upgrade” and a final window will appear asking for confirmation. Once the
upgrade process has started it cannot be stopped and the Sumo will reboot at the end of the process.
Do not interrupt the upgrade process once it is underway, or power off the device. The process will
take 2 minutes.
