    Frequently Questions About POE

    What is "POE"?

    PoE is " Power over Etherenet". A device like this one take DC power and injects on one or both pairs of wire in the Ethernet cable. It's used to power IP cameras, VOIP phones, Wifi Access Points and other networks devices.

    What is the difference between Mode A and Mode B?

    Mode A and Mode B are two different POE pinouts ( the wire pairs used to transmit power).

    Mode matters most if you're powering a 24-volt passive PoE devices like those from Mikrotik or Ubiquiti. These devices always need Mode B.

    If you're powering a devices that has a spec of “802.3af” (48 Volts), them eighter mode A or mode B should work.

    What does passive POE mean?

    Passive PoE means the PoE Injector is always on rather than negotiating with the powered device to turn on and off as need.

    Which power supply do I need?

    The power supply will depend on the specs of the powered devices. Most VOIP phones and IP cameras use 802.3af PoE, which requires a 48 volt power supply. For Wifi, check your device specs for either 802.3af or 24 volt passive.
