24port POE+ switch, PCB design

Former Member
Former Member over 9 years ago

So we are moving soon and I am going through my parts bin and I found 5 Molex 8 port 10/100/1000 POE+ modules (through hole, not surface mount... NEW). I am not sure 100% how difficult it would be to make a PCB to mount these too and other components of course to make a handy switch. 24 port or more, I am thinking when we get moved and in to our new house I can see needing a minimum of a 24 port switch. Where do I start?


edit : : I've also got a lot of other stuff in the bin too, including but not limited too a handful of USB 2.0 mini-b and Mini-b OTG ports (through hole, NEW as well.), USB 2.0 Type A right angle ports, etc.
just found a handful micro USB type-B OTG and mini-HDMI as well.

    Doing the POE part might not be too bad, depends a bit on how much your Molex modules do. The 24 port switch is  a big challenge for a one off, you will struggle to get enough support from the chip makers to design it and it will very likely need a multilayer (> 4 layers) board and BGA footprints. One pcb will cost way more than a bought in switch.

     

    If you are desperate for fun you might be able to take the innards of a non POE 24 port switch and use your Molex modules to convert to a 24 port POE switch.

    Yeah, I figured it wouldn't be cost effective but I'm not sure what else to do with the parts.
