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 7-17 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
