Yes, you can connect two RPI Pro units to the two SFP+ ports on the AS6 Pro.
The AS6 Pro's SFP+ ports are backward compatible with 1G SFP modules. We recommend using the same type/specification of 1G SFP module on both ends of each connection.
Please note that you should not use a 10G SFP+ module on the AS6 Pro side and a 1G SFP module on the RPI Pro side. Both ends should use matching 1G SFP modules.
