After connecting the card in the system, only one of the ports appears to be functional, and the card has been tested in different PCI ports and a different system, a Dell PowerEdge R740.
It is important to review the bifurcation settings in BIOS to ensure the card is working with PCIe x16 bifurcation enabled. There have been reports from customers that were able to solve this issue by enabling the bifurcation setting in the system BIOS.
Please contact the system/platform manufacturer for detailed instructions on how to perform the necessary adjustments.
