Power over Ethernet – the elegant power supply via LAN cabling
LANCOM Access Points are prepared for the PoE power supply (Power-over-Ethernet), corre-
sponding to the 802.3af standard. PoE-enabled network devices can be comfortably supplied
with power feeding through the LAN wiring. A separate external power supply for each base
station is unnecessary, which reduces the installation complexity considerably.
The power feeding into the LAN happens at a central position, either via a PoE power injector,
or via a so-called powerhub/powerswitch. For the LAN wiring is to note that all 8 wires must
be available by the cabling. PoE feeds the power over those four wires, which are normally not
used for data transfer.
The PoE supply works only in such network segments, in which exclusively PoE-capable devices
are operating. The protection of network devices without PoE support is guaranteed by an intel-
ligent mechanism, that tests the network segment for devices without PoE support before start-
ing the PoE power feeding. The power is only switched onto the segment, if only devices with
PoE support were detected.
In a PoE installation use exclusively devices which correspond to the 802.3af standard!
For damages caused by inadmissible devices no warranty may be claimed.
