NOTE: If you see an A200 output when you have an digital card, this is normal
Remove or change the riser board: Change the riser board and check if the card shows up in LSPCI. If this doesn’t work then connect the card to PCI slot.
Reseating the card on PCI Slot: Try reseating the card in the same PCI slot and then run LSPCI command to see if the card comes back up again. This will rule out the possibilities of card not properly seated in the PCI slot.
Trying with different PCI slot: Try to reseat the card on a different PCI slot available on the same server. This will ensure whether that PCI slot is faulty or not
Testing with different server: Place the card in a different server and see if the card shows up in LSPCI. If still the card is not coming up.
