Installing the Switch
Sample Network Topologies
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 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 
Auto-MDIX feature on the 2520G-PoE switches.
