    It looks like those are for parts items, they may not be functional or only partially so. I would definitely contact the seller before purchasing!

    If even one port works then that's a killer deal. Even if it doesn't it's like buying an expensive bracket.

    I picked up two as a test. I had to strip the low profile brackets but it looks like both ports work on them. I tested with an sfp+ adapter connected to a dac. Just some basic functionality testing, link, ping, etc.

    Do you mean you bought the ones with 'damaged ports' and they seem to work fine?

    So far, yes. I'm able to pass traffic on both ports with the two cards. I'm using a qsfp to sfp+ adapter, so ymmv. I only have 10gb switches available for testing. I've ordered some more cards, I'll report back when I get them. Later this week hopefully I'll be cutting over to these cards for most devices in my racks. Wish me luck.

    Nice, guess the cards with the damaged ports were FCCT / the 'Pro' version ?
    Desperately looking for a high-res image of an FCCT circuit board to compare with FCBT / get an idea if there is any difference in HW at all between those.

    The seller also has a listing of similar cards without a bracket. Also damaged.
    There it says that "net1 flare socket worn out".
    Anyone have an idea what this means for simple homelab use?

    thanks!
    I consider patching mstflint to allow fcct fw to fcbt adapters - there is a check in it that throws an error, and i guess there is not really another reason than this check why it doesn't work.
    whith your pics i can now check if physical hw is identical before ;)

    cool, this should give you vxlan offload and other goodies.
    have you tried the cx354a-fcct vpi fw, too ?
    think it should work when the card doesn't refuse the pro-fw for EN ;)
