Socket Direct (2x PCIe x16) Cards Installation Instructions
The hardware installation section uses the terminology of white and black harnesses to differentiate between the two supplied cables. Due to supply chain
variations, some cards may be supplied with two black harnesses instead. To clarify the difference between these two harnesses, one black harness was
marked with a "WHITE" label and the other with a "BLACK" label.
The Cabline harness marked with "WHITE" label should be connected to the connector on the ConnectX-6 and PCIe card engraved with "White Cable"
while the one marked with "BLACK" label should be connected to the connector on the ConnectX-6 and PCIe card engraved with "Black Cable".
