can't access the mikrotik router board rb951ui

Hello,
I have just buy a new mikrotik rb951ui fro a small coffee shop i have. I was recommended to the product by my producer. The problem i have is that i try to connect to it following the manual set up but i can’t. Winbox can’t locate the router and the browser doesn’t open the set up page when i add the mac address. Is there any advise you could give me or is there any manual to see. I have to mention that i have no experience in networks.
Thank you in advance

Hi.
Did you tried it with WinBox software? It can locate your router on local network without correct setup, just on MAC-address.

Than you for your answer
Yes i have but it can’t located. Is there any other way to do it?

Hello, connect to ether 2 to ether5 and try again.
Don’t use ether1
