The examples shown in Figure 55-2are described in detail as follows:

Example 1: Single Cisco IP Phone 7960

Example 1 shows one IP phone that is connected to the 10/100 port on the Catalyst 6500 series switch. The PC-to-phone jack on the phone is not used. The phone can be powered through the 10/100 port or wall powered.

Example 2: Single PC

Example 2 shows one PC that is connected to the 10/100 port on the Catalyst 6500 series switch. The PC is wall powered.

Example 3: One Cisco IP Phone 7960 and One PC

Example 3 shows one IP phone that is connected to the 10/100 port on the Catalyst 6500 series switch and one PC that is connected to the PC-to-phone jack on the phone. The PC behaves as if it is connected directly to the 10/100 port on the Catalyst 6500 series switch. The phone can be powered through the 10/100 port or wall powered. The PC must be wall powered.

Example 4: Two Cisco IP Phone 7960s and One PC

Example 4 shows two IP phones that are connected to the 10/100 port on the Catalyst 6500 series switch and one PC that is connected to the PC-to-phone jack on the phone. The PC behaves as if it is connected directly to the 10/100 port on the Catalyst 6500 series switch. The first phone can be powered through the 10/100 port or wall powered. The second phone and the PC must be wall powered.

Note For more information on configuring the Cisco IP phones and third-party vendor phones, refer to the documentation that shipped with the phone.
