I tried testing the Mellanx QSFP to SFP+ adaptor with the SFP side of a QSFP to 4xSFP+ copper cable .
The result was what looks like corrupted/dead EEPROM - unable to recognize the cable anywhere .
Has anyone see this issue.
Do you have the schematic of what looks like a interconnect PCBinside the Mellanox adaptor. Thanks
