SpiderCloud Radio Node - SCRN-220 Hardware Installation Guide
11
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 pair of wire pairs in the cable. The radio node will expect a nominal
48V DC input (57V max) from a typical PoE+ injector.
