Power-over-Ethernet – elegant power supply through the LAN wiring
LANCOM 3550 Wireless base stations are prepared for the PoE power supply (Power-over-
Ethernet). 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 unneces-
sary, which reduces the the installation com-
plexity considerably.
The power feeding into the LAN happens at a
central position, either via a PoE power injec-
tor, 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 intelligent mechanism, that tests the network segment for devices without PoE support
before starting the PoE power feeding. The power is only switched onto the segment if only
devices with PoE support were detected.
LANCOM 3550 Wireless supports the proprietary PoE solution by PowerDsine. It is not fully
compatible to the finshed standard 802.3af. Although, most of the currently on the marked
available Power Hubs and Power Injectors are compatible to the pre-standard of 802.3af. The
PowerDsine Hubs of the 6024, 6012 and 6006 series have been tested by LANCOM Systems
for full interoparability. For damages caused by inadmissible devices no warranty may be
claimed.
