Hi Dave,

Do you have access to any PoE injectors in that case?

The two hats I ordered worked fine off the hop-though I’ve read about concerns with the surface mounted 4-pin connector on the hat. I’ve used them with a Ubiquiti PoE inejector that came with an UAP-AC-PRO and with a netgear switch, I think I did briefly test one in my US-8-60w without issue.

Hi Troy,
yup the port is configured for 802.3AF.
24V would kill the Pi

Hi Dave,

Is the PoE Port set to 802.3af (PoE) and not passive 24v?

I believe those switches can do both-but the Pi is only made for 802.3af.

Hi Shabaz,

It is just the plain Pi without anything connected to USB.
I have a Ubiquity 8 Port 150W switch.

Hi Dave,

Does it work if you disconnect all additional loads (such as USB drives etc)?
Have you enabled PoE on your switch? What precise model is your switch, does it support standards-based PoE?
Some PoE injectors are not standards based.

Hey guys,
Just got a brand new Pi3B+ with PoE Hat.
If I plug it in to a PoE injector or to my Ubiquiti PoE switch it does not start at all as in no leds burning.
If I use the normal power adaptor it boots without problem. I can even see the cpu cooler go on every now and then.
Do I still need to configure something in raspi-config to enable the PoE hat?

I ordered two in June, they too arrived earlier this week. I put one through the ringer with an old USB HDD that required two USB ports and it seemed okay.

both that one and the other have been up and running for days without any of the horror stories-I just haven’t tried them yet with any other USB devices.

Well, mine arrived a couple days ago from Newark/Element14. Apparently about a month after folks who ordered them elsewhere, which was disappointing since I've had them back-ordered for about 6 months.

Now, it seems I was lucky to even get them, as a design defect has been found and nobody's selling them now; a recall may be pending. Apparently the power being output is very noisy, which is bad in itself, and one of the symptoms is that the USB/Ethernet chip resets frequently and it can't power a USB device over 200mA.

Hey Shabaz remember that Bitscope Blade unit I had you can do POE insertion with that and it seems more flexable for many applications
