4 Product Architecture
The PTP 500 Series Bridge is fully software upgradeable. New software images are first
downloaded from the Motorola website http://www.motorola.com/ptp to a convenient
computer. The image is then uploaded to the ODU via the web management page described
in Section 8.3.6 "Software Upgrade". The compressed image is first loaded into RAM and
check-summed. If the compressed image transfer has completed successfully the image is
decompressed and written to flash memory. On completion of this process the unit can be
rebooted to use the newly uploaded image. Should this process fail, the unit will revert to a
protected compressed image installed during manufacturing to allow the unit to be recovered.
