 The EA4500 has a dual firmware layout:  working and backup partitions.  It boots from the working partition in normal operation.  Firmware flashes occur on the backup partition and the EA4500 shall reboot from the backup partition following from a firmware flash.  The backup partition becomes the new working partition when the reboot was successful.  The former working partition becomes the new backup partition. The EA4500 has a dual firmware layout:  working and backup partitions.  It boots from the working partition in normal operation.  Firmware flashes occur on the backup partition and the EA4500 shall reboot from the backup partition following from a firmware flash.  The backup partition becomes the new working partition when the reboot was successful.  The former working partition becomes the new backup partition.
