How to configure the mikrotik switch

I have 4 fiber optic cables and a ethernet cable and I don’t know how to configure the router
Btw; I’m using winbox
I need to know which address I should use
I have 4 plc IP adresses and the router address and the master address
What should I do with the detailed steps please?!
Thanks in advance
