When using SFP+Modules, do not mix 2.5/5Gbps and 10Gbps link-speed as the hardware does not support mixing these due to different frequencies.
While most standard LC-LC OM3 SFP+ modules and SFP+ Direct Attached Cables are likely to function we advise to select one of of the known compliant modules from the following list:
