I'm complted test with varioty copper cables. All QSFP+ cables work propery.
I can't find any symbol errors on 5035 switch during 3 hours load test and 12 hours real simulation test.
It seems registered cable data on 5035 can't works with FDR14 active optical cables.
This is a POC environment and stay in 4036 QDR Fabric in production one.
When all HCA, Switch, driver prepared then I'll test again.
