Hello,
I have PiKVM V4 Plus and the switch. I wonder if I can power both from a PoE splitter? Is it possible? Is it safe to do?
Hey AxelD, welcome to the forum!
I don’t see any reason why it won’t be possible. To be on the safe side, you need to make sure that your splitter and the upstream PoE switch can supply 30W (24W for the PiKVM V4 Plus and 6W for the PiKVM Switch), and have a compatible coaxial connector (+12V on the inner terminal, ground on the outer — see bundled power supply for reference). Switch can be powered daisy chain from the V4+.
Hope this helps.
What do you mean by “powered daisy chain”?
You can connect the 12V out on the V4 Plus to the 12V in on the Switch, so that you don’t need a splitter with two leads. Please see the diagram below – the daisy chain power connection is in red (#4).
Thank you so much! You’ve been most helpful.
In practice the v4 Plus will rarely take 24w on its own if you don’t have a WWAN card installed, so you can often do one or two Switches plus the v4 Plus off a single 12v 2A PoE splitter, and 12v 3A splitters are becoming more common/available now.
Good to know, thank you.
Personally I’ve had great luck with the Revodata spiltters from Amazon, just make sure you get the 5.5x2.5 mm ones rather than the 5.5x2.1mm version, the latter might fit but you also might need an adapter, and that’s just another point of failure/poor connection down the road.
