Networking a new screen and CP370

Hi team. I apologise if I am asking ridiculously simple questions. I currently have an A127 MFD and a Raymarine Autopilot that are networked via a 5 way network switch. There is also an old transducer that plugs straight into the back of the MFD.

I now want to add a second A127 MFD to the network as well as a new 1kw transducer via a CP370 DSM. I know the transducer plugs into the DSM but my questions are...

1. does the DSM then plug into the 5 way network switch or directly into the back of one of the MFD's? and...

2. if I connect the 2nd MFD via the 5 way network switch will all the devices be networked together ie both screens (individually) will have access to the chartplotter and autopilot and the new depth sounder, so I can pick which screen shows which data?

Thanks for your assistance with this one.
