Providing Power to the Cisco Unified IP Phone
You can power a Cisco Unified IP Phone 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 Unified 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-X6348-RJ45V 10/100 switching module—Inline power provider to the
Cisco Unified IP Phone when connected to a Catalyst 6000 family
10/100BaseTX switching module.
This module sends power on pins 1 & 2 and 3 & 6, which are also used to
transmit Ethernet signals. Before the switch sends power, it tests for the
presence of a Cisco Unified IP Phone, avoiding damage to other Ethernet
devices.
Note Only the network port supports inline power from the Cisco Catalyst
switches.
WS-PWR-PANEL—power patch panel that allows the Cisco Unified 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 Unified IP Phone before providing power.
