Did you let it plugged in for the three days? Or did you remove it and plugged it in again after three days?
I'm asking because when I got my connect x2 card and connected it directly to one of the sfp+ ports of my xeon d mainboard it took over 3 minutes to get a link. Maybe it's the same for this switch.
I left it plugged in for three days.
At my server room I spent probably 3-3 1/2 hours trying to get it to work on day 1 (when the DACs arrived). I had two DACs shown, one plugged into a Windows PC that works fine with the UBNT transceiver + fiber cable, and the other was my Proxmox node.
In the end port 8 DAC, works with the Proxmox and PC, but all the other ports won't work with the DAC cable.
Oh and I did install a software update a few minutes ago to go from 3.7.24.5422 to 3.7.29.5446.
So far the issue is the same though :/.
At least my Proxmox box has SFP+ finally
