US-16-150W 48V PoE support

Hello all,

 

Could someone from Ubiquiti confirm that the US-16-150W switch supports 48V PoE/PoE+? I am currently trying to resolve an issue with a product manufacturer who are claiming that the switch does not support this.

Re: US-16-150W 48V PoE support

Thank you all for your responses.

 

Apologies, it's actually a US-24-250W.

 

I understand that 802.3af and 802.3at is supported, but the manufacturer of this product is saying that somehow 48V output is not supported in these modes by the switch. I don't believe this since the 802.3at/at standards support up to 57V or something aroud that, which is why I'm asking for confirmation to send that back to them.

There's no such thing as '48V output', unless he means a passive 48V injector. Ask him if he means 802.3af/at.

It is supposed to and this is the reason why I purchased one. 

But... there are issues on the POE at least at the 16 Port switches. They keep rebooting all the time. Check the threads

US-16-150W restarting AP-AC-Pro every 5 minutes...

- USW-16-POW-150W dropping POE but not overheating
