      Has anyone got a Yealink phone to work with POE over CAT 3, 6 conductor cable?

      I have confirmed that 802.3af supports 2 pair POE/data.
      https://en.wikipedia.org/wiki/Power_over_Ethernet (assuming wiki is correct)

      And the Yealink phones support 802.3af class 2 POE, so I should be go to go.

      The part I'm assuming at this this point is the use of 568B pinout in the jacks. (more specifically, using pins 1, 2, 3, 6)

      Thoughts?

        Or just replace that CAT3...

          Stupid answer as usual.

          Cat 3 has always supported 10/100 and PoE.

            But it may not fill whatever could go in this place later on.

            It's not a stupid answer to upgrade when applicable.

            Now if this is a wall jack that's 4 feet off the ground it may not make sense, but your stance doesn't either.

              You are not technically using T568 at all. You are making use of the T568B standard for reference and using pins 1,2,3,6.

              568 A or B does not matter. it simply has to be the same on both sides. I personally like B just because it is what I first used when I learned CAT5 wiring.

                It absolutely will work for any device plugged in here that uses standards, because it IS a standard.

                  LOL - yeah, in most cases it is a wall jack 4+ feet off the ground. 😉

                      OK found the answer for switch side - The Edgeswitch 48 port outputs 802.3af only in mode A OR 24 VDC Passive in Mode B.

                      I love how UBNT spells out the specific pins in use.

                      Supposedly the spec states that end devices have to be prepared for either mode A or mode B based upon the current sending device, so I should be covered. But now I'll go dig through the specs on the yealink phones.

                        The yealink docs just don't say.

                        At this point, I'm left assuming they support mode A and Mode B.
