Follow the on-screen prompts for downloading the file.

"Download in progress, please wait," is displayed.
CAUTION: Make sure the unit is not reset or powered down at this time. A loss
of power while the new code is moved to flash could result in loss of
bootcode. The unit would then have to be returned to the factory for
replacement of the bootcode.
Swapping Software Versions and Resetting
1.
Once Download is complete, the new version resides in the inactive flash memory region. To
make it operational, it must be swapped with the active region. If you are still viewing the
TFTP Operation Screen, press Enter to return to the Software Upgrade Screen.
2.
To Swap software versions, type "2." The Swap Bank option will be highlighted. Press Enter.
3.
Modem will reboot, then go online with the new software now active. The inactive flash
memory region contains the old version. It can be swapped back (again made active), should
a problem occur.
After swapping software versions, the older version now resides in the inactive flash memory
bank. If the module displays unexpected behavior using the newer revision, or the upgrade
became somehow corrupted, just swap the two memory banks again, and the module can quickly
be brought back online using the previous software version.
Copying the Software Upgrade to Other Modems
With the DMM, software revisions can be simultaneously uploaded to every modem requiring it.
You need not upgrade each modem one at a time. Standalone modem pairs sharing data with a
chassis-based modem, can be upgraded in a single session. When TFTP is used, all modems in a
link are simultaneously upgraded.
1.
To copy the new software version to other modules, from the Software Upgrade screen,
type "4."
2.
To upload the new software to other modules, follow the on-screen prompts.
8.3.3 Installing into a Standalone Modem Via the Serial Port
You can download the new firmware version to your 2361 Modem via a serial port. The Canoga
Perkins website has a small DOS-based program called
dwnfirm
.
exe
to facilitate this process. To
access it, log on and select Downloads from the Canoga Perkins home page.
The
dwnfirm.exe
program can be used to individually upgrade the modem's active firmware.
These are separate files and can be recognized by their file extension:
