HPE 5900AF to Dell S5212F over custom dual-coded DAC: no link, transceiver does not support this function
1
The poster tried to link an HPE FlexFabric 5900AF and a Dell S5212F-ON at 10 Gbps with DAC cables that had been custom-made with an HPE-coded end and a Dell-coded end. Both ports were forced to 10G full duplex, but no link came up. On the HPE side the interface reported Media type is stack wire, port hardware type is STACK_SFP_PLUS, and diagnostic commands returned The transceiver does not support this function, pointing at an unrecognised cable.

An HPE employee listed the approved HPE DAC part numbers (JD095C, JD096C, JD097C, JG081C, JC784C) and the Dell DAC-SFP-10G series, suggested checking that each coded end was plugged into the matching switch, and trying auto speed/duplex instead of forced settings.
