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.
Step 3 Connect an Ethernet cable from the injector’s OUT port to the radio node. The injector will
now inject power onto a blue and brown wire pairs in the cable. The radio node will expect a
nominal 48V DC input (57V max) from a typical PoE+ injector.
