4.8.5.2.3 SW Versions Control
The AU can contain two SW versions:
Main: Each time the AU resets it will reboot using the version defined as Main.
Shadow: Normally, the Shadow version is the backup version. Each time a new

replacing the previous Shadow Version.
The process of upgrading to a new SW version is controlled by the NPU, and is
performed using one of the AU SW files installed in the NPU. If the specified AU
SW file does not exist in the AU, it will be downloaded to the AU and the requested
