Nexcom NI 184C card does not work correctly on pfsense 2.6

luckybuilding

Hi all,
I would like to install pfsense on a Nexcom appliance with Bypass capable NIC cards to bypass the traffic on power disruption or anything else happening to pfsense OS. Now, pfsense detects the hardware and is working. However, the NIC does not come up after connecting the network cable and it functions in bypass mode. pciconf shows:
PCI-e errors: Correctable Error Detected
Unsupported Request Detected

The network card is shown as Intel I350 card.

Can anybody help me resolve the problem?

Thanks

That usually requires a special driver that likely doesn't exist for FreeBSD.
Otherwise there may be jumpers to disable the bypass mode. Or BIOS settings to do the same.

Thanks for the reply. Where can I find the driver?

the card does not mention any driver on the page. However, it seems to be supported on FreeBSD.. Because, other bypass cards has such a drivers:

Do you think they are exchangeable?

No idea. Ask Nexcom? They probably don't have a FreeBSD driver though.

I would not expect those cards/drivers to be exchangeable. There's no standard for this so companies use different IO interfaces to control the relays.

If you're very lucky someone else might have already documented it.
