I bought a pair of Ubiquiti 10G transceivers to connect two Unifi switches. Ports lit up but connection didn't work. I tried everything: static IPs, hardcoded the connection speed, tried a different cable and whatever I thought about what I read at the time (that was a few months ago). I put everything back on auto, hooked up the transceivers and everything just worked. No problems after a few months. I will definitely buy them again when the time comes.
