AP134 and Power Injector

  • 1.  AP134 and Power Injector

    Posted Mar 28, 2014 12:14 PM

    Hi All,

     

    I have the following strange behavior regarding AP134.

     

    If I connect them on POE switches (802.3af) they work without problems.

    I have an error about the insufficien POE voltage on eth1 but I have read on the manuale that it's correct:

     

    Shutting down eth1 due to insufficient POE voltage

     

    If I use power injectors, AP134 power on (power led is green), but the eth0 port is not able to goes up:

    Time out

     

    The ETH0 led is not power on.

     

    If I connect on the same power injector an AP105, it works without problems....

     

    Is it possible?

    Someone can help me?

     

    Thanks,

    Gian

    What is the model power injector?  The AP125 could draw more power than the AP105.

    Thanks Cjoseph for your support.

     

    The power injector is a common object (ARP product). 

    From the AP134 DS I read:

     

    POWER
    • 48 volts DC 802.3af power over Ethernet (PoE) or 802.3at PoE+
    - Note: when using 802.3af POE, the second Ethernet port is disabled. It is enabled when using an 802.3at POE power source (or direct DC power).

     

    I was hoping that 802.3af was enough.

     

    Best Regards

    Gian

    gianti81,

     

    I would try a different model of power injector and see if you achieve the same result, because they are not all created equal.  It does work with POE.
