Newbie queston on Netgear GS105eV2 set up

I'm sure this is basic, but I am lost on all the networking set up. I have a Mikrotik routerboard tunneling to the AREDN mesh through a hardwired internet connection. I also have two RF nodes: an 18inch dish and a Nanostation. I would like to be able to access each of these three nodes from my computer. I have all three nodes plus the computer plugged into the Netgear GS105eV2 switch. I am only able to access the routerboard. How do I select what I can connect to?

Thanks!!
