Input Power
The radio node receives its power from a standard Power Over Ethernet (PoE+) switch (typical) or injector.
The radio node is fully compliant with the IEEE 802.3at PoE+ specification.
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.
When connecting the radio node to a PoE+ switch, ensure that the switch port is statically configured to
deliver minimum 25W of power.
Figure 8 shows the valid radio node cabling/powering options:
Figure 8 Valid Radio Node Cabling/Powering Options
Power is distributed over two pairs of the four available pairs in Cat 5e or better cables. The
radio node can accept power on either used or un-used pairs.
Some PoE switches may be factory configured to deliver lower power per port. If this is the
case change the configuration during installation.
