Introduction Introduction
About Power Over Ethernet (POE)
The DWL-P100 Power Over Ethernet (POE) Adapters are design to supply
operational power to a Wireless Access Point. These Power Over Ethernet
Adapters give users the ability to mount an Access Point virtually anywhere
in a building no matter where the power outlet is located such as ceilings,
attics, or roofs. It eliminates the need to use an AC-DC power supply at the
Access Point making the setup more convenient. D-Link's DWL-P100 Power
Over Ethernet Adapters take advantage of the unused cable pairs within
Ethernet Cat 5 cabling. The Base Unit inserts DC voltage into the unused
wires therefore allowing the single Category 5 cable to carry both E thernet
data and DC power to an Access Point. The POE Terminal Unit splits the data
and DC power apart, which is then supplied to the Access Point.
