Err, I just bought one of these from City Technology (in Victoria) last week....
Do you have any more details about this recall? Who were you looking at ordering from?
UBNT Team - Is there something we should be worried about?

POE blow ups when using 24v static + shielded cables, before week 25 this year are affected (date code before mac addres on sticker 2516). Mine 16 ports also....But i do not have the issues as i only use POE 48volt, this protocol seems not affected.
There is also an POE issue with the UAP-AC-LITE and UAP-AC-LR from a specific date due to hardware changes, so a lot going on with POE ;(
Negative side effect is that is fries all you network equipment if the sh*t hits the fan, i disabled all POE on the not used ports by default. Just to be sure....
All info from the forum so if you take you time you can find all the specific topics containing fragments of information.

I'm glad they put that up BTW and will be ordering through them once this is resolved. Thanks for the extra info wopper.

My date code (4 digits before MAC address) seems to be 1620:
I'll give City Technology a call on Monday and see if they were aware of this. There is nothing on their website that mentions this:
I literally only just bought this and set it up, so It will be a bit of a pain if I have to go back on-site and rip it out to swap it over...*sigh*.
Is this the post you were referring to?
If not, are you able to post a link to the thread please?

Hi, just bought UniFi Switch 8 POE-150W and am currently using this with 2 UAP--AC-Pro's along with 4 POE IP Camera's. Looking at the date code mine starts with 1618 as well. Is there any reason for me to be worried about?
Should I contact the supplier? Unifi chat support suggested no RMA unless the device is fault.

Here is the official link to the issue: http://community.ubnt.com/t5/UniFi-Wireless/Warning-UAP-AC-LITE-and-UAP-AC-LR-with-UniFi-Switch-on-P...
It is a corner case and rarely happens. But to avoid any future RMAs, we are replacing distributor stock.

Well, this is exactly what happened to me. I set up a new system with a UAP-AC-LITE plugged into a US-8-150W, with a shielded Cat7 cable and it blow out the POE module on the UAP-AC-LITE.
I've sent the UAP-AC-LITE back to the distributor but they have been most unhelpful in trying to sort this out.
I would also like to get the affected US-8-150W replaced for peace of mind. I don’t like the idea of a 24/7 piece of equipment with this kind of potential for failure. I’m somewhat concerned that I might damage something else that’s plugged into the switch on a hard reset .

Yah i can confirm a blown ethernet port too ...nice and toasty lol even the port in the switch melted

@hairybear101 We'll get this taken care of for you.
Shielded cable between the UAP-AC-LITE, UAP-AC-LR and the UniFi Switches is not recommended at this time: http://community.ubnt.com/t5/UniFi-Wireless/Warning-UAP-AC-LITE-and-UAP-AC-LR-with-UniFi-Switch-on-P...
Anyways, we'll get this sorted out for you.
