Chapter 70 PoE Configuration
70.1 Introduction to PoE
PoE (Power over Ethernet) is a technology to provide direct currents for some IP-based terminals (such as IP
phones, APs of wireless LANs and network cameras) while transmitting data to them. Such DC-receiving
devices are called PD (Powered Device). The max. distance of reliable power supply provided by PoE is 100
meters.
IEEE 802.3af standard is a new PoE standard, and an extension to the current Ethernet standard by adding
new items on power supply via network cables to IEEE 802.3 standard. It is also the first international
standard on power distribution.
The application of PoE used to be in two areas: IP phone and 802.11 wireless network, however, along with
the development of this technology, many applications with more practical meanings have emerged and
benefited from PoE, such as video monitoring, integrated building management solution, and remote video
service booth. All these existing and predictably more of such applications arouse needs for switches
supporting PoE.
