6.3.4 Software Upgrade
The 45 Mbps Backhaul system has two software image banks; one is a fixed image which is stored in protected
non-volatile memory and is not modifiable by the user, the second bank is used by the system administrator to
upgrade the firmware as and when necessary. Figure 23 shows the main software upgrade webpage.
Figure 23 Software Upgrade
The ‘Fixed’ image is only used if disaster recovery is required, i.e. if an upgrade process is interrupted or the
units are reset to their factory defaults.
These pages are used to update a unit’s operational software. The software image to be uploaded should be
downloaded to local storage from the Canopy website at http://www.motorola.com/canopy. The software image
is delivered by Motorola as a compressed zip file. Once the zip file has been downloaded the user should extract
the 45 Mbps Backhaul Software image, identifiable by its ‘.dld’ file extension.
The first step (Figure 23) is to use the “Browse” button to locate the software image previously downloaded to
local storage from the Canopy website. Once the image is located the user should press the “Upload image to
wireless unit” button to start the software upgrade process.
The software image will now be uploaded to the unit where it will be stored in SDRAM until it is committed to
the unit’s non-volatile memory. This upload should only take a few seconds, once complete the image is
verified and validated to ensure that no errors occurred during transfer and the image is valid to run on the
current platform. If there are any problems a warning screen will appear.
The unit being upgraded will now display information about the build it currently has stored in the image bank
and the one that’s just been uploaded. If the image is not the right one the user has the option to go back and
reload a new image. (See Figure 23)
