Per IEEE 802.3at, use standard Cat 5e or better twisted-pair cable with a maximum length restriction of
100 meters (328 feet) for PoE+. This restriction minimizes power loss between the PoE+ power source
and the radio node.
Figure 8 shows the valid radio node cabling/powering options:
Figure 8 Valid Radio Node Cabling/Powering Options
The illustration below shows a generic single-port PoE+ injector. Use this injector only when a PoE+
Ethernet switch is not available.
Figure 9 Typical PoE+ Injector
To connect the PoE+ injector to a radio node
Step 1 Attach the injector power cord to a power source.
Step 2 Connect an unpowered Ethernet cable from a switch to the IN port on the injector.
Power is distributed over two pairs of the four available pairs in Cat 5e cables. The radio
node can accept power on either used or un-used pairs.
