Quote from: meyergru on November 22, 2025, 07:36:32 PMI have never encountered any compatibility problems with 10G DAC cables.Sadly I have. Some switch manufacturers are pretty crazy these days with DAC compatibility. Ubiquiti is not one of them though, I got gifted 2 unused DACs from Netgear stuff someone threw away and those had no problem working within a Unifi switch and a OPNsense test hardware. But Unifi SFP(+)s are quite reasonable when it comes to pricing plus with their SFP programmer hardware it shouldn't be hard to make the necessary "changes" to a module to make it ... say more "appealing" to specific switch vendors if needed ;)
And yes, I almost had the same setup in my lab at one point, just with the older USW-8-Enterprise-PoE but the setup works. One SFP+ to the firewall one to another server (or switch - the 8-port aggregation is really cheap for that) and you're ready to play around with 10G LAN stuff.
Cheers
