Chapter 7 Configuring the Switch Ports

Configuring Inline Power on the Catalyst 3524-PWR Ports

The Catalyst 3524-PWR XL can supply inline power to the Cisco 7960 IP Phone, if necessary. The

Cisco 7960 IP Phone can also be connected to an AC power source and supply its own power to the voice

circuit. When the Cisco 7960 IP Phone supplies its own power, any Catalyst 2900 XL or

Catalyst 3500 XL can forward IP voice traffic to and from the phone.

The Catalyst 3524-PWR XL senses if it is connected to a Cisco 7960 IP Phone. If there is no power on

the circuit, the switch supplies the power. If there is power on the circuit, the switch does not supply it.

You can configure the switch to never supply power to the Cisco 7960 IP Phone and to disable the

detection mechanism. See the “Configuring Voice Ports” section on page 7-14 for the CLI commands

that you use to supply inline power to a Cisco 7960 IP Phone.

Beginning in privileged EXEC mode, follow these steps to configure a port to never supply power to

Cisco 7960 IP Phones.
