If the downloader application is running, use a web browser on the same logical network
as the device to access the device’s configuration web pages (see Section 3 “Configuring
the Platform"). From here, the device’s network and system settings may be reconfigured.
These pages provide two options for downloading a new firmware application image
to the device. If you wish to download the new firmware image using TFTP, enter the
filename of the ROM image, and enter the IP address of the TFTP server on which this
file resides. Press "Start TFTP Download" to initiate the TFTP download process.
If the ROM image is stored on the same local machine you are using to access the
device’s web pages, you can choose to download the ROM file to the device using an
HTTP post. Enter the filename of the ROM image, or press "Browse" to help locate the
file. Press "Start HTTP Download" to initiate the HTTP download process.
