I have red a lot, especially from Simon in Surfolk, about the cisco switches and their SQ they can provide with good Ethernet clock. Currently I'm using a TP-Link 3210 between my Raspberry PI (3) / NAS and NDX. It sounds good but I would like to try the possible difference with a cisco 2960.
I can acquire a C2960 PD without a PS. It can be powered with a external PS or with PoE. Has someone tried this? Which electrical feeding of the switch is preferable?
Thanks for your replays in advance.

I'd say that if you are going to lay out the money for the switch, you might as well buy the external supply to ensure that the switch is optimally powered.
It's not the same thing I know, but my Cisco WAP371 gets better throughput with an external supply.

Hello Juanito,
I have the switch but I don't have a PoE injector or a PSU. The original PSU has the same specs as PoE feeding port (48VDC / 15.4W).
Theoretically the switch can draw the same amout of power in both feeding possibilities. Only thing I can imagine is the "speed" of the power when it has to be delivered. Perhaps a external PSU can switch faster to provide. Could that be it?
