Power over Ethernet – the elegant power supply via LAN cabling
Electricity supply to the LANCOM OAP Wireless takes place via Power over Ethernet. This
requires the use of the Power Injector as included in the scope of supply.
The use of other PoE injector devices, e.g. those compliant with the IEEE 802.3af stand-
ard, is not permitted and using them can cause damage to the devices. The LANCOM
OAP Wireless has a power consumption of up to 25 Watts when operating at its full
heating or cooling capacity. The resulting flow of current in the PoE cable places con-
straints on the length of cable that can be used.
Due to the high power consumption of the LANCOM OAP Wireless, a disturbance-free power
supply can only be assured with PoE cabling of up to 50m in length.
For the same reason, the maximum length of cable to the next Ethernet switch may not exceed
50m, even if the PoE feed takes place over a shorter length of cable (e.g. when using the 15m
cable).
To this end, the 15m PoE cable with a waterproof thread as supplied with the LANCOM OAP
Wireless can simply be extended with a coupler. An Ethernet cable coupler and Cat 5 Ethernet
cable are available from specialist resellers.
Please ensure that all cables used are of at least Cat 5 quality. All four conductor pairs
must have contact through all of the cables.
The 1Port Power Injector supplied with the LANCOM OAP Wireless does not comply
fully with the IEEE 802.3af standard. It is suitable for supplying power to the LAN port
of the LANCOM OAP-54 Wireless only. If you wish to safely supply power to other
devices with IEEE802.3af, LANCOM can supply a proprietary LANCOM PoE Injector.
