What do I do if the RJ45 jacks from number 25 to 28 of switch SW3224POE-GC-350 are not working?

Ports 25, 26, 27 and 28 do not respect any PoE standard; furthermore, if the corresponding SFP ports are used, these RJ45 ports will automatically cease to function.

Namely: if the SFP port number 25 is used, the RJ45 port number 25 will stop working.

 

This concept is known as Combo Port: the same electronic board accepts signals from different connectors, but while using a specific connector there is no other card left to process the second signal, so the other connectors will not work.
