Sample Network Topologies for PWR Switches
Installing the Switch
As a Segment Switch Implementing PoE
As shown in the illustration above, the IP telephones have been inserted in
between the Switch 2650-PWR and the PCs, and a WAP has been connected
to the Switch 2650-PWR. Both the telephones and WAP will receive PoE power
from the Switch 2650-PWR. Only devices directly connected to the PWR
switches can receive PoE power if they are 802.3af compliant, except on the
Switch 2600-8-PWR, it has the ability to supply power to pre-802.3af-standard
devices, such as legacy (or non-standard) IP phones. Devices connected to a
non-PWR segment switch cannot receive PoE power.
