Hi, there is an document "
9035978-03_XMC_User_Guide_8.2.pdf" available - which explains on
page 428 ff the "
Fabric Manager ZTP+ Configuration" process.
I agree it's difficult to locate these documents - I'd prefer to find them on the same page as document collection there you'll find the software.
Currently software and documents are located on different locations.
On this URL you'll find an document archive, which includes all available (31) documents:
https://www.extremenetworks.com/support/documentation/extreme-management-center-8-2/
Good luck
