i may be reading wrong.
You need both the side 10GB -SR to work
or 1GB SFP to work
10GB to 1GB not going to work.
Also worth checking the compatible matrix.
I also tried a Cisco SFP-10G-SR on both devices still no luck - I would like to see the config and I take both cisco Optics ?
what patch cable are you using OM4 ? or OS2 ?
show interface tenx/x (see is the SFP recognized)
try no speed negotiation auto see if that works
