Installing the Switch

Sample Network Topologies for PoE+ Switches

As a Segment Switch Implementing PoE

Figure 2-24. Segment network configuration with PoE+ switches

As shown in the illustration above, the IP telephones have been inserted in
between the E2620-48-PoE+ Switch and the PCs, and wireless access points
(WAPs) have been connected to another E2620-48-PoE+ Switch. Both the
telephones and WAPs will receive PoE+ power from each of the switches.
Only devices directly connected to the PoE+ switches can receive PoE+
power. Devices connected to a non-PoE+ segment switch cannot receive
PoE+ power.
