This section shows a few sample network topologies for implementing the
Switch E2620-PoE+ Series. For more topology information, see the HP

As a Desktop Switch Implementing PoE+
Figure 2-23. Basic desktop configuration with external power
The Switch E2620-PoE+ Series are also designed to be used as desktop
switches to which end nodes, printers and other peripherals, and servers are
directly connected, as shown in the above illustration. Except now these
switches can supply PoE power to end devices such as IP telephones.
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 E2620-PoE+ Switches.
