GS110EMX 10GB-LAN connection

Hello there,

I am no techie, and in these days and esp. in this city it is complicated to get a good admin to handle what I am about to ask you. Nothing special I guess but, as I said, I am no techie, I just understand the basics.

I need to set up a simple 10 Gb connection to my Synology NAS to work more efficiently and faster with huge Photoshop files. I bought the affordable GS110EMX switch for that (I thought). It should connect (and now already connects via 1Gb LAN connection) my router (Fritz 7490), printer, NAS 1 (Synology D412+), NAS 2 (Synology 1819+) and my PC (Windows 10 Pro). So I can either use both NAS via LAN on my PC or via WLAN on my Mac laptop (in a different room).

The PC (with 10Gb network card) is connected via 6a cat cable with the GS110EMX port 9, the NAS 2 (Synology 1819+ with 10Gb-card) is on port 10 with 6 cat cable. All others are connected via the ports 1 to 8 (router, NAS 1, printer).

My simple theory is: I work directly on my NAS 2 via the 10Gb-connection set up from my PC to the GS110EMX switch (port 9) which connects to the NAS2 through port 10 and get the full power from this 10Gb connection. I still want to connect via Mac > WLAN/Router to my NAS 2 and can live with the lower 1Gb connection between router and switch.

Is my thinking right here? Is that possible at all? Or does this setup automatically downgrade to 1Gb? Did I buy the right switch for that? And, if yes, can you explain in a relatively simple way how to connect the NAS 2 so I get the full 10Gb via PC?

Or should I buy a new router which is 10Gb able?

Let me know, appreciate any help.

Thx! Alex
