Network switching apparatus for supplying power to network communication equipment through twisted pair line
First Claim
1. A network switching apparatus for supplying power to network communication equipment, the network switching apparatus comprising;
- a network switching circuit for exchanging packets;
at least one socket, each connected to a RJ-45 connector having a twisted pair line so as to electrically connect the network switching apparatus to a corresponding socket of the network communication equipment through the twisted pair line; and
an internal power control circuit electrically connected to the corresponding socket of the network switching apparatus, the power control circuit being operable to generate signals having a predetermined frequency and in accordance with specifications stipulated in IEEE 802.3af, transmit the signals having the predetermined frequency to the network communication equipment through pins of the socket, and supply power of the network switching apparatus to the network communication equipment through the RJ-45 connector and the twisted pair line thereof in response to signals received from the network communication equipment.
