Hi everyone,

I have a Poweredge RX11 without OS. I installed a PCIe card (https://nateurope.com/product/npcie-uplink-o/) in slot 3, which is (like all other PCIe slots) in a riser-cage. Installed in a PC, the card is enumerated in the PCIe network as "System peripheral: PLX Technology, Inc. Device 87d0", so I can assume, that at least the PCIe-endpoint of the card is functional. But installed in the riser, the PCIe overview in the LOM states, that the slot is empty, without any error message.

Could it be, that the card would be discovered during the OS boot-up?
Do PCIe cards need to fulfill some specifications, to work with a riser?

Best
