*** Official Ubiquiti Discussion Thread ***

Silly question, but are you sure they're not powered on? From memory until they are adopted and configured that have a white glow to them instead of blue and unless the room is dark it's not very noticeable.

That's entirely possible, I'll try again in a little while. But neither the infinity software or the cloud key can find them. Could I have damaged them by feeding 48V into them before I switched the switch to 24V? I'm tempted to RMA these and get a 5-pack of Pro's instead because they seem more compatible with 'standard' networking stuff. Or buy a Ubiquiti switch, but it just seems crazy to rip out half my network to get better WiFi in the far reaches of the building.
 
The Lite and LR only run off 24v PoE, your TP-Link switch will have been attempting standards-based PoE but this shouldn't have caused an issue at all in terms of damage - it just wouldn't have powered up.

Assuming your switch is this one http://www.tp-link.com/us/products/details/cat-40_T1600G-52PS.html, I am not sure what you mean about it running at 48v before switching to 24v - that's not something the switch supports.

I bought 3 Ubiquiti U-AP-AC-LR access points, all singles with PoE injectors in the boxes.

None of them will power up. Not from the supplied PoE injectors or from my TP-Link TP-1600 52 PoE switch. The switch is capable of af and at flavours of PoE and it happily powers the Ubiquiti Cloud Switch so it should work, I think.

Can I really be so unlucky as to have got 3 duff access points or am I doing something fundamentally wrong?

24v passive only which is outside of what your switch will provide. When you power them it will take a minute or 2 for the ring to light up then it should start blinking to show they are looking for a controller.

I have three PoE options in the mode column. AF, AT and P which I believe is 24V. I'm quite happy to be informed differently. The same supplier supplied everything so it's no problem sending anything back if it's not compatible.
 
It's entirely undocumented in that case. If you supplied the Unifi APs with 48v passive PoE then I would say that's the likely cause of your issues.

The online manual doesn't match the firmware in the switch if that's what you mean. But then the online manual doesn't show anything at all in the PD Mode column, it just shows dashes and the explanation for what it's about just says it shows the type of device connected, which isn't that helpful either.

But the fact that they stay dark when powered from the supplied POE injectors would suggest they are not working. And yes, I suspect that shoving 48V through a 24V device probably wouldn't do it any good.

Luckily I bpught it all from one supplier, on their advice, so they won't quibble when I send it back broken (if it is broken). Never mind. Next week is a new vista....

And thank you for the help, you've obviously actually looked into it and I appreciate that.

If you powered them first from the switch then you have burnt them out, Ubiquiti use propriety passive POE on the current stock of LR and Lite, new stock circulating in America uses standard POE as well as Passive.

Yes, it does look like that's what has happened. As I say, it's a good thing I got everything from one reputable supplier, and asked for advice before ordering. Obviously, it appears to have been bad advice, but there won't be any issues returning it for a replacement, I'm sure.

I suppose the next question is should I ask for a 5-pack of pros rather than 3 LR units, especially since the Pros seem to be compatible with "standard" PoE.

See my edited reply above https://www.reddit.com/r/Ubiquiti/comments/5unz3z/uapaclrs_now_supporting_8023af_seems_like/ If you won't want to wait and don't want to use the injectors then yes then yes the Pros would be what you would have to get.

My outer box sleeves do not have the blue stickers. I wonder if the sales advisor was a bit previous in advising the LR with the TP-Link switch or whether I should have set the ports to P before I plugged them in.

I'll ring them first thing in the morning and get it sorted.

Thanks again for the help.
 
You should have configured the PoE first (assuming that there actually is a compatible PoE setting). They should also have warned you that it was necessary.

Killing all three was a good trick. Did you kill them individually or all in one go?

One after the other I'm afraid.

It was that "This is dead, I'll just try this one" and then "Two dead ones? That can't be right...."

But yes, in hindsight I possibly should have broken out the PoE injectors earlier in the orgy of destruction.

Got a photo of the injectors you're using?

I can get one. It's the Ubiquiti one supplied in the box with each unit. I didn't buy a multi-pack, I bought three individual units with PoE injectors. The white light is on on the injector so it is getting power. I've only actually tested one injector so it's not impossible I've got a duff injector rather than bad access points.

I'll give it a go, but I'm not holding out much hope at this point.

You absolutely can kill a device expecting 24v passive PoE by feeding it 48v passive PoE. 802.3af/at are cleverer than that.
 
I thought that these APs had built in protection against 48v.

I've certainly had non IT staff trying to connect them up to wrong ports. Not had any die.

Edit, maybe it's just the 48v ubiquiti bricks that don't fry them..
