Figure 2-17. As a Desktop Switch Implementing PoE.

This illustration is the same as figure 2-16, except now the switch is configured to supply PoE power to end devices such as IP telephones and wireless access points (WAPs).

As shown in the above illustration the IP telephones can be connected in line, that is, between the switch and the end device, in this case a PC. The IP telephones in this illustration have two ports, one in and one out. Therefore the phone receives voice and power from the switch, and the PC can send and receive data through the phone to the switch.

The end node devices are connected to the switch by straight-through or crossover twisted-pair cables. Either cable type can be used because of the “IEEE Auto MDI/MDI-X” features on the switch.
