I have a customer with non-HP Brocade 6520 switches that are under HP support so Brocade will not allow downloads!
Hence why I'm asking if using the FOS downloaded from HP is ok. The switches have Brocade licenses installed.
Thanks for the response, I actually managed to get a download from Brocade (via IBM site) and compared with HP zip file - exactly the same size when the 2 HP files (EULA and ancollary.txt) were removed. Also the Release Notes on HP website reference the Brocade switches so all good to go.
