Power over Ethernet
The twisted pair ports on the
A device that receives its power over an Ethernet cable is called a powered device. Examples of such devices can be wireless access points, IP telephones, webcams, and even other Ethernet switches. A powered device connected to a port on the switch will receive both network traffic and power over the same twisted pair cable.
The switch automatically determines whether a device connected to a port is a powered device or not. A powered device has a signature resistor or signature capacitor that the switch can detect over the Ethernet cabling. If the resistor or capacitor is present, the switch assumes that the device is a powered device.
