Installation
To install the Power over Ethernet Splitter, please follow the steps below.
1. Use an RJ-45 cable to connect the Data In port on the Power over
Ethernet Splitter Adapter with the Data Out port of a PoE Hub. If the
hub does not support PoE function, you'll need to install a PoE Injector
(pn: POE-32001T) between the hub and splitter.
2. Use an RJ-45 cable to connect the Data Out port on the PoE Splitter
Adapter to a remote device (Such as a router, access point, camera,
etc.).
3. Choose the proper power cable (either 2.0mm or 2.5mm) and plug the
straight end into the Power Out port on the Splitter.
4. Plug the right-angle end of the power cable into the device’s power
port.
5. Adjust the Voltage on the Splitter to match the remote device. It
supports four voltage values – 5V, 7.5V, 9V and 12V. The default
value is 5V. Before adjusting the DIPswitch, please disconnect the
power from the Splitter Adapter.
6. Before powering on the system, ensure all connections and the voltage
is set correctly.
The PoE Splitter connects to the Switch or POE Injector in the
Data In port.
The PoE Splitter connects to the remote device through two
connection ports – Data Out and Power Out.
The voltage is set correctly: 5V, 7.5V, 9V and 12V.
