Network Switches

I received the  "Silent Angel" Bonn N8  Ethernet Network Switch yesterday and plan to hook it up today.
My question is whether to connect it close to my router or close to my server?  The router and server are connected by a 35-foot Ethernet cable.
If close to the router I can use my HD Plex LPS that is powering my router to also power the switch, but if close to the server then I would have a very short cable from the switch to the server and would probably use the Bonn N8 PS to power the switch.  If close to the server, I can plug the Bonn's PS into my Isoclean 60A3 II power filter.  Otherwise, if the switch is close to the server, I can use the router's own power supply to power the router, and move the Plex LPS close to my server, plug it into the Isoclean 60A3 II, and use it to power the switch.  Any clear direction or do I need to do some trial and error?  Which option do you guys presume would be best? Thanks

@mitch2   Based on my understanding of your post and questions....I would place the N8 Switch close to your Server. Run the long cable from your Router to the N8 Switch. I believe this will give you the best performance. As always, you will need to work through the options to find out for yourself and your system.

Looking forward to learning about how it works out!

Re. the Power Supply applications....always best to optimize on the audio side first. In your situation, if I understand your post correctly, I would use the HDPlex with your server over the Router. If you were to get an additional LPS, then use it with the Router as the next step.

Thanks for the help. I will try the switch close to the server.  To be clear on the PS issue, the HD Plex LPS was a spare I had around so I connected it to power my router rather than the wall wort that came with the router.
My server has a great internal PS so the choice is whether to use the Plex on the router (as it is now) or on the switch instead of the PS that comes with the N8.  However, if I were to put the switch close to the router, instead of close to the server, then I could use the HD Plex LPS to power both the router and the switch.  I will first try the switch close to the server using the PS that comes with the switch but plugged into my IsoClean 60A filter.  Maybe later I will try moving the LPS from the router to the switch.
Thanks again for the help.

Ok, so I optimized the Bonn N8 switch by positioning it very close to my Antipodes DX3 server, using the short Ethernet cable that came with the N8 to connect with the server, using my HD Plex LPS to power the N8, and plugging the LPS into my IsoClean A60 power filter.  Since I moved the LPS to power the N8 switch, I am back to using the stock PS to power the Orbi router.
There seems to be a sonic improvement but certainly not night and day.  I would say smoother and maybe a bit more tonal depth.
