Yesterday I finally performed some surgery on the Buffalo switch. I removed its internal switch mode PSU and soldered a DC cable to the board so I could now power it @12V from the Keces linear PSU. I also disconnected the LED PCB and configured the switch.
After that was done I also switched the power supply to my FritzBox VDSL router from an old, 1st model 12V SBooster BOTWS to the second Keces DC output. Both outputs are isolated from each other and floating.
Forgot to mention in my previous post that I had also ordered the popular Planet Tech single mode 1310nm 20km SFP’s. These were only 29 euro or so on Amazon so worth the experiment. Will replace my current Cisco multi-mode SFP’s with these later, need to establish a new ‘baseline’ first.
The Buffalo switch is a L2/L3 switch so I will also create a separate VLAN to isolate the music server and endpoint from the rest of my network. Doesn’t cost anything and should work with the benefit it won’t see any broadcast traffic from the rest of my network.
While I had the Buffalo switch open I took some pictures and searched from some inside pictures of the Melco S100 switch (€2000,-) and seeteeyou was right; the PCB’s are the same..there may be some differences and there may not be. Hard to say without having a S100 here for close inspection. The S100 does have an additional board with some capacitors. I could add something like that later but with a good PSU this may not even be worth it.
My Buffalo before soldering the DC lead and with the SMPS still in but disconnected.
