Connecting Your Phone’s Power
If you are using an external power source, plug it into the building’s power source,
and plug the power supply into the phone base. See Figure 1 on page 29, item #2.
If you are using Power over Ethernet (PoE) to power the phone, the phone will
receive power when you connect an Ethernet cable from the phone’s WAN port to
a switch in your network that provides PoE. See the ”Connecting Your Phone to the
Wired Network” section on page 34.
NOTE: The SPA525G does not ship with a
power supply. If you are not using Power over
Ethernet (PoE), you must order the PA-100
power supply separately from Cisco.
