B.3.1.4 Step 4: Downloading the Image to the AU Flash
The AU flash can store two AU images: shadow and operational. The operational
image is the image that is currently mapped to the AU slot, and is used for booting
the AU when the AU is reset. The shadow image is the image that is downloaded
from the NPU flash.
After you have created the AU-to-image mapping for a particular AU slot,
download the image from the NPU flash to the AU flash. To download the image to
the AU flash, run the following command.
npu(config)# load to au [<au slot-id>] shadow <shadow image name>
