Updating the SMM, SMM-1 Firmware
The SMM software is comprised of two files: SMMImage1.S19 and SMMImage2.S19. These
two files are compressed images of the software that runs the SMM application code when
the module powers up. Two images are provided as a backup in case one Image fails. This
enables you to protect your system against a bad software image because there will always
be two images to run. Either image performs exactly the same functions. When the first
image is loaded and run, it will use the new software. If both SMM images are not upgraded
at the same time, the old image will not have all of the new features, and will run the older
version of firmware. The two images can be found on the CHP System CD under the Firmware
directory.
Before you begin
1. Insert the CHP System CD, (P/N CHP-CMS-1). If you wish to load the GUI software you
can do so at this time, or stop the auto install and proceed to open up an Explorer
window to copy the files from the CHP System CD.
2. Make a directory on your local hard drive to store the SMM firmware files. The
instructions will refer to the latest System release files in a directory as shown in
Figure 6.24 on page 6-35. The directory name can be any name, but ARRIS strongly
recommends using the system release numbers located on the latest CHP System
CD to ensure using the correct files. These files will need to be accessed in the future
if the SMM module is replaced, or needs to be loaded again.
3. Copy the SMMImage1.S19 and the SMMImage2.S19 files from the System CD to the
PC where the files can be FTP’d to the local SMM module. File Transfer Protocol (FTP)
does not require an HMS download tool.
4. Ensure connectivity with the CHP SMM module by using the Ping command in a DOS
command tool window from your computer as shown in Figure 6.23 on page 6-34.
The download will not work unless there is connectivity to the SMM from the PC.
