Ethernet FTP Upload Procedure
1. Identify the reflashable product, firmware number, and version for download.
The current base modem M&C version can be viewed at the top level menu of the front
panel display (press the CLEAR key several times to view). The firmware information can
also be found within the (Select) Utility: Firmware
Image#2 menu trees.
Using serial remote control, the firmware revision levels can be queried with the
following commands:
For more information about remote commands, see Appendix A. REMOTE CONTROL.
Alternately, when using the Web Server Interface, the Bootrom, Image1 and Image2
firmware loads may be viewed after selecting the Firmware Info hyperlink (available
under the Status page tab). For more information, refer to Chapter 6.5 Web Server
(HTTP) Interface.
2. Create a temporary directory (folder) on an external PC.
Windows: Select File > New > Folder, then rename the New Folder to "temp" or another
convenient, unused name. Assuming "temp" works, a "c:\temp" folder should now be
created.
Note: The c: is the drive letter used in this example. Any valid writable drive letter can
be used.
CMD Prompt: At the command prompt (c:\>), type "mkdir temp" or "MD temp" without
quotes (mkdir and MD stand for make directory). This is the same as creating a new folder
from Windows. There should now be a "c:\temp" subdirectory created (where c: is the
drive letter used in the example).
3. Download the correct firmware file to this temporary folder. As shown in Figure 4-1:
About Firmware Numbers, File Versions, and Formats: The flashable files on the download
server are organized by product prefix; firmware number (verify that the correct firmware
number is known – see Step 1); revision letter, if applicable; and release version. The base
modem bulk firmware for the CDM-740 is FW-0000279X_V### (where 'X' denotes the
revision letter, and '###' the firmware version).
The current version firmware release is provided. If applicable, one version prior to the
current release is also available. Be sure to identify and download the desired version.
