~~ This is the one thing I don ' t get . It sounds like the singlePoEout version only does PoE when powered via PoE . That ' s the handiest feature , IMO you could power both it and a downstream AP . But why can ' t it also do PoEout when being powered with the adapter ? That would make just as much sense , especially if your primary switch isn ' t PoE . ~~ EDIT Didn ' t realize y ' all were talking about the Mikrotik here . I was referring to the Ubnt . <| sep |> That was separate but also a consequence of the same thing . It ' s to do with the BBFCs age ratings system that is applied to other formats . They haven ' t actually banned anything . It ' s just that the BBFC is going to be regulating online material in the same way it applies age ratings to other formats . The rules that govern their ratings system haven ' t been changed in years . In fact it could be more likely , now that the ratings are going to be affecting more people , that they will be changed to better reflect modern society .
