Information about PoE
Power over Ethernet Ports
A PoE-capable switch port automatically supplies power to one of these connected devices if the switch senses
that there is no power on the circuit:
•
a Cisco pre-standard powered device (such as a Cisco IP Phone or a Cisco Aironet Access Point)
•
an IEEE 802.3af-compliant powered device
•
an IEEE 802.3at-compliant powered device
A powered device can receive redundant power when it is connected to a PoE switch port and to an AC power
source. The device does not receive redundant power when it is only connected to the PoE port.
