    Unifi APs

    Do Unifi APs need to use the PoE injectors they come with them or can an 802.11af PoE switch be used. The AP I'm looking at is the UAP-LR

    They include their own "injector"

    I don't think the UAP-LR is 802.11af compatible

    That doesn't really answer my question. I've already read that and the only thing I can conclude from that PDF is that you NEED to use the PoE injector on the low end APs unless you buy the PRO AP.

    Unifi, Unifi LR and Unifi Outdoor require their own PoE injector, or a suitable midspan, as they operate at 24v. They indeed aren't 802.11af compliant.

    The Unifi Pro however are, and can be run from any 48v PoE switch.

    Not quite sure why you can't read the pdf properly:

    Specifications (UAP-LR)
    UniFi AP Long-Range
    Dimensions 200 x 200 x 36.5 mm
    Weight 290 g (430 g with Mounting Kits)
    Networking Interface (1) 10/100 Ethernet Port
    Buttons Reset
    Antennas Integrated 3 dBi Omni (Supports 2x2 MIMO with Spatial Diversity)
    Wi-Fi Standards 802.11 b/g/n*
    Power Method Passive Power over Ethernet (12-24V)Power Supply 24V, 0.5A PoE Adapter Included
    It's therefore quite obvious that they're not compliant and that as I said you have to use the injector that they provide and as you've rightly said yourself it's only hte PRO AP that is POE compliant.

    I'm not super clear on what the OP wanted to hear. The only piece of information I've spelt out, over and above that from the PDF is that can use a power source other than the supplied injector, but it has to be a specific 24v item.

    If you wish to use the standard UAPs, UAP-LRs etc (basically, all but the Pro and AC models) with a 802.3af switch then you can purchase in-line adapters that convert it to passive PoE. We use the standard UAPs, ProCurve PoE switches and these adapters work fine.

    I seemed to have ruffled a few feathers, sorry. All I wanted to know was whether or not they needed to use PoE injectors. It wasn't clear to me in the unifi literature. Adding unnecessary wiring from a PoE injector isn't what I was looking for however those in-line adapters look ideal.

    Sorry again for any confusion.

    Please investigate those further - there are many posts here and elsewhere saying those adapters are not good.

    On the contrary we've only had 1 fail in over a year of using them. We've got close to 100 on our site.

    Same here, got about a 100 across a few sites, only ever had one play up, cheap enough to replace. Unlike any other managed solution...if you think what you save on bloated maintenance charges, plenty to cover the cost of the odd AP

    I would just buy the Pro's and be done with it, there is some extra cost but the the extra port and dual band make it worthwhile in ease of setup (daisy chaining etc.) Once you have bought std uap's plus inline adapters plus extra cable Im not sure you actually save any money and you get better unit with the Pros. As always up to you though!
