What is Power-over-Ethernet(乙太網路供電)?
現有的乙太網Cat.5佈線基礎架構不作做何改動的情況下,在爲一些基於IP的終端(如IP電話機、無線局域網接入點AP、網路攝像機等)傳輸資料信號的同時,還能爲此類設備提供直流供電的技術。
IEEE 802.3af standards based雙絞線上輸出44~57V的直流電壓、350~400mA的直流電流

The PoE Standardization 802.3af
• June 2003 – IEEE802.3af-2003 ratified– Over 68% of lines in the standard were written
by PowerDsine !!
志遠電子股份有限公司 http://www.techmosa.com.tw/chinese/home.htm 2006/5/26 Page 8
• Power – Transmit power only for authenticated compatible terminals (e.g.: IP Phones or WLAN Access Points, Security Cameras, etc.)
• Safe solution – Automatically blocks power to legacy Ethernet devices (e.g.: Laptops, NICs, switches, etc.)
• System Protection – Protect systems against overloads and short-circuits
• Compatibility - Compatible with standard Category 5 (and above) cabling infrastructure , no need to replace cables, patch-panels, RJ-45 outlets, etc.
IEEE 802.3af – Main Objectives
志遠電子股份有限公司 http://www.techmosa.com.tw/chinese/home.htm 2006/5/26 Page 9
PSE output: 350mA continuous, 44Vdc to 57Vdc.
PSE continuous average output power: 15.4W min.
PD allowed consumed power: 12.95W max.
Midspan supplies power on spare pairs only: 4/5 (+), 7/8 (-)
Endspan supplies power on either data pairs: 1/2 (-), 3/6 (+) or spare pairs: 4/5 (+), 7/8 (-).

PoE Process
Det.
• PD Detection is performed to decide whether the terminal is PoE enabled.
• PD Classification determines PD’s consumed power prior to its powering.
• Startup Process is done gradually to avoid data interference.
• Operation - Real-Time Protection & Power Management ensure safe operation
• PD Disconnection is monitored causing the port’s power to shutdown
•

Classification Function
Class PSE (W)0 15.41 42 73 15.44 As Class 0
PSE stabilizes a 20V signal, for 30ms, over the port output, and measures the consumed current.
The consumed current indicates the PD’s power consumption class
Class Current (mA)0 0 - 41 9-122 17 - 203 26 - 304 36 - 44
Example: a PD with a maximal power consumption of 7 W should be classified as class 2.
Under 18V it should consume 17 to 20 mA to indicate this class.
