Inline power for IP Phones uses connector pins 1, 2, 3, and 6 in a Category 5,
Category 5e, or Category 6 cable to transmit power (6.3 W) from the switch. This
method of supplying power is sometimes called phantom power because the IP
Phone power travels over the same pairs of wires used to transmit the Ethernet
signals. The IP Phone voltage is completely transparent to the Ethernet signals
and does not interfere with their operation.
