I have been running the Ubiquiti UACC-CM-RJ45-MG modules in my USW Aggregation switches since the modules first appeared in the EU UI store. Not a single problem here. One is serving the 2.5G link to my main internet router and I am monitoring the line / router with Zabbix, problems would not have gone unnoticed.The question is whether they do it well though?There are modules that technically support it but that have all sorts of issues in practice.
