    Power Injector Switch

    Hi,

    Can I use a power injector switch to provide power to Wireless Access Points that are not PoE enabled? Something I have not tried before but would like to know before it goes ahead.

    Thanks

    No. If it's not PoE enabled, how is it going to receive the power from your injector?

    Beat me to it. You can't power an Access Point if it's not PoE capable.

    I think if you tried it your only going to damage the WAP. So I think its definitely a no - no.

    Hi,

    I did wonder! The problem is that my supplier failed to send me APs that supported PoE (me ordering a PoE switch at the same time didn't click in!) However when I explained they came back with this

    Business Product

    I have been told it works but again have never tried it. I thought the power injector switch would be just the same. Please feel free to comment

    You can buy POE plug adapters, is that what you mean? We use 2 here becuase the switch ran out of ports. They work perfect.

    Would work,

    The DWL-P50 Power over Ethernet adapter is a single-port splitter that provides DC power for a non-PoE-equipped device, such as a surveillance camera or a wireless access point.
    Basically the Wifi point would get the power from the DWL-P50 which would get it from POE switch.

    Thanks Matt,

    The only problem I can see from the picture provided on the link i posted is the DC power socket on the splitter. Having not used one of these before I am thinking that I will have to plug in 12 plugs (as I have 12 APs) somewhere for these to work. From what you have said it sounds like I can use the PoE switch I purchased to substitute the need for the plug.

    I use these devices, but the other way around from you - we have PoE capable access points but no PoE switch. You only actually need the receiver end of that device listed, you don't need to use the bit that plugs in to the wall and provides power over the Ethernet cable. I don't think you can buy them separately, though. Check the connection type and voltage on your access point, the device outputs either 5v or 12v.

    @Rob998
    To be honest it sounds like your Supplier messed up, from reading the stuff on the D-Link website, it sounds like you can use either 5VDC/12VDC, so you should be fine (assuming AP is D-Link, shouldn't matter tho), I assume it comes with all the bits you need.

    Should just need to plug your switch in, plug the AP(s) into the DWL-P50(s) and the DWL-P50 into the switch and it should just work. Failing that, contact your supplier, example you've tried it, you know he's messed up, you've tried the more [expensive\harder\cr@ppy] way he's recommend, and you want POE AP.

    Nah, you shouldnt do. Some of our network points in our office are connected to PoE ports (for testing WAPs) and we can plug various non PoE equipment into them and no problems

    I though POE uses the extra 4 unsed core's so it dose not effect any non POE device!
