    I just got a POE switch.  I was wondering if anyone was using or providing POE device that supports PFSENSE?

      The ALIX is PoE capable.
      Although not completly PoE compliant.
      The standard voltage of PoE is 48V.
      The ALIX board is designed to work with 7-20 V.

      We do what we must, because we can.

        There's passive PoE and then there's 802.3af.

        Passive PoE is what is used by the Alix boards, Ubiquiti APs, etc.  It simply sends DC over 4/5 and has return on 7/8 and can range anywhere from 5-24V depending on the device (most are in the 15-20V range).  Using a Passive PoE adapter with a non-PoE device can cause a lot of damage.

        802.3af is what you're going to get out of a PoE switch.  It is commonly used for IP Phones, security cameras, name-brand wireless access points, etc.  It runs 48V DC and has a detection process where power is only provided to a device that needs it, meaning you can use a PoE switch with non-PoE devices.

        If you want to use a device that requires Passive PoE with an 802.3af PoE switch, you can use an adapter like this:

        I can break anything.
