Configuring Inline Power
The Catalyst 4500 series switch senses if it is connected to a Cisco 7960 IP phone. The Catalyst 4500
series switch can supply inline power to the Cisco 7960 IP phone if there is no power on the circuit. The
Cisco 7960 IP phone can also be connected to an AC power source and supply its own power to the voice
circuit. If there is power on the circuit, the switch does not supply it.
You can configure the switch not to supply power to the Cisco 7960 IP phone and to disable the detection
mechanism. See the
