Providing Power to the Cisco IP Phone
You can power a Cisco IP Phone from an external power supply, from a switch
port, or from a power source between the phone and the switch.
The Cisco IP Phone can be powered by the following sources:
• External power—optional Cisco AC adapter and power cord for connecting
to a standard wall receptacle.
• Inline power—inline power provider to the Cisco IP Phone when connected
to a Cisco Catalyst switch capable of providing inline power.
Note Only the network port supports inline power from the
Cisco Catalyst switches.
• WS-PWR-PANEL—power patch panel that allows the Cisco IP Phone to be
connected to existing Catalyst 4000, 5000, and 6000 family 10/100BaseTX
switching modules.
This module sends power on pins 4, 5, 7, & 8, which are not used for Ethernet
signaling. The power patch panel also attempts to verify that the attached
device is a Cisco IP Phone before providing power.
