If you attempt to retrieve a system image from Management Center using the Content Analysis (CA) CLI, image installation fails
Management Center certificate is not trusted by the Content Analysis.
Due to the inability to openly modify the trust package on the CAS, the retrieve image will function only with HTTP enabled and used for image retrieval from MC.
Management Center commands:
enable
security http enable
Then from UI of Content Analysis:
System > Firmware > Retrieve Image: <input HTTP link generated by Management Center>
Press retrieve
From CLI:
enable
config
installed-systems
load <http link generated by Management Center>
