Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network
Providing Power to the Cisco Unified IP Phone
After the phone obtains one of the .cnf.xml files or the .cnf file, it requests a
phone-specific profile file. If a phone cannot find this profile file, it requests the
appropriate common profile file. For more information about profile files, see
Appendix A, “Additional Configuration Methods and Parameters.”
After the phone finds one of the profile files, or if it cannot find a profile file, it
continues with its startup process.

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.
