Hello everyone, I am trying to figure out what are the dimensions of the hAP ax2 DC jack. Is it 5.5/2mm or 5.5/2.1mm? I would like to power it over PoE with the RBGPOE PoE injector on the other end (which seems to be 5.5/2.1mm) and I am not sure whether the adapter that comes with the router would actually fit or whether I would need to buy a different adapter for that. Thanks a lot for any help.
the second you said.
Only for the record, 5.5/2 mm does not exist in IEC standard (the most common), there are 5.5/2.1 and 5.5/2.5 mm:

Thanks a lot. I got confused by hAP ac² - User manuals - MikroTik Documentation , where it says
5.5mm outside and 2mm inside
I thought it meant 5.5/2.0 and I suspected that it might be the case for the ax2 too.
Anyway - am I right that the RGBPOE PoE injector accepts the same 5.5/2.1 mm jacks and should therefore be compatible with the adapter that comes with the router? Thanks a lot for the help!
Yep 
, I think we can say that Mikrotik devices with a barrel jack socket are all 5.5/2.1.
