Appendix B - Software Upgrade Upgrading the AU
4Motion 704 System Manual
However, the AU is immediately shut down after it boots up with the operational
image.
npu(config)# reboot au [<au slot-id>] shadow [<shadow image name>]
Specify the image name that you have used for creating the mapping in, “Step 3:
Creating the AU-to-Image Mapping” on page 701. If you define another image
name in this command, the AU-to-image mapping is updated with this image
(provided this image is also residing in the NPU flash). Specify the slot ID if you
want to reboot a specific AU slot with this image. If you want to reboot all the AU
slots with this image, do not specify any slot ID. In addition, the mappings for all
AUs are updated with this image.
After you run this command, the software version that is used to reboot the AU is
the operational version. This version will be used for rebooting after the next AU
reset.
IMPORTANT
An error may occur if:
 The AU image is not present in the NPU flash.
 You execute this command immediately after inserting the AU card, and it is still registering itself
with the 4Motion system.
 The software image version is incompatible with the hardware.
 Rebooting the AU with the shadow image has failed. (The AU boots up with the operational
image, and then initiates self-shut down.
IMPORTANT
Do not delete this image from the NPU flash because this image is used to boot up the AU the next
timeit is reset . If you delete this image from the NPU flash, the default AU-to-image mapping will be
used to reboot the AU.
