• The firmware upgrade file has a .zip file extension. (Do not unzip this file. Downloading it
will automatically expand the files appropriately.)
To install the new version, do the following:
1. First, download the new firmware or bootcode version from Canoga Perkins website to your
server's root directory.
2. Put the dwnfirm.exe program (a single executable file) in the same folder as the firmware or
bootcode version just installed.
3. Attach the modem via the serial port to the PC.
4. dwnfirm.exe must be launched with the file name that must be downloaded to the modem. A
specific argument must be used.
• To upgrade the modem's firmware, use the following argument:
C:\dwnfirm 2x6x0173.zip
Note: Please look at the command line carefully before beginning the download
process. Make sure you include the entire path name where the dwnfirm.exe file and
bootcode file are located. In the example above, the path is
C:\dwnfirm.exe
.
Replace that path with the correct path where your files are stored.
Note: To obtain help with specific command usage for this program, type
dwnfirm ?
in the directory where the dwnfirm.exe file is located.
5. As soon as dwnfirm.exe is started, the modem should be reset.
6. The file transfer is done at 115200bps and the progress is shown on the PC screen.
7. The bootcode will verify the file integrity, then burn it to the inactive bank or the bootcode
FLASH. The newly downloaded file will then be made active automatically and it will be
decompressed in DRAM.
