Dell PowerEdge 2850 does not recognize AJA PCI-e (PCI Express) card

Medium Priority
Last Modified: 2012-05-06
I have a fresh install of Windows 2K3 R2 on my Dell PowerEdge 2850. I got the OS up and running without any problems, and then popped in my AJA LHe PCIe card. For those unfamiliar with the AJA card, it is used for encoding and decoding in video editing.... but that should be irrelevant to my problem since there is nothing even coming up in the device manager as an Unknown Device.

Figure A-5 from Dell's website here: http://www.mohca.gov.bt/~susumu/other/dell/2850/data/pe2850/doc/en/it_en/t1393aa0.htm#wp1041040 shows the PCIx 4x-lane slot, which I put the card into (it is also 4x). Just for fun, I put the card in the 8x slot too, which the system also did not recognize.

So I'm out of ideas. I checked the bios, all the startup hardware configs, etc... I can't find anything that will seem to "enable" anything plugged into the pci riser card on my PowerEdge.

1) do you have the latest BIOS ?

2) Are you sure the card is OK ?

I hope this helps !

1) Yes, I do now
2) There is a power light that turns on when the system boots up. I do not have another system to test this in, so I cannot be sure that the card works in any other machine. I will try to find a machine that I can take offline that also has a PCIe slot.

The only thing I can think of now is that it has something to do with the embedded card settings in the server BIOS. Hardware-wise, there is SCSI cable connecting SCSI A above the hard drive enclosures to the SCSI A connection on the PCI riser. There is nothing connecting SCSI B. In the BIOS, SCSI A is set to RAID, not SCSI, while SCSI B is set to SCSI. When I connected a cable to B, the system would not boot as it said it detected a cable connected to B but no daughtercard was present. If I switch SCSI A from RAID to SCSI in the BIOS, during boot is pops up a warning saying that a configuration change was detected and asks me to confirm. If I say yes, it says data loss may occur.

Are my actual hard drives connected to the system through SCSI A cable set on a RAID setting, or will nothing happen if I switch the configuration?


I am sending the card back for a replacement.
