Chapter 3 Connecting the PoE Injector
You can use TL-POE150S PoE Injector with PD or PoE Splitter
to expand your network to where there are no power lines or
outlets, where you wish to fix devices such as APs, IP Cameras
or IP Phones, etc. The following steps will tell you how to
connect the PoE Injector correctly.
1. Use a CAT5 UTP cable to connect port of Ethernet device
(such as a switch, hub or router) to the LAN IN port.
2. Please connect the power adapter properly to a power
socket with provided power cable, and then connect the
other end of the power adapter to the DC 48V port of the
TL-POE150S.
3. Connect the POWER+DATA OUT port of the TL-POE150S
to a PD or a PoE Splitter with CAT 5 UTP cable.
Now, the device can work normally with data and power.
There are two schemes to realize the PoE.
1. If the device supports PoE (take an IP camera with PoE for
example), following topology will work:
LAN IN: Connect to a
network device (such as a
Switch or Router ) with
CAT5 UTP cable. DC 48V: Connect to the
provided power adapter
which can supply steady
power of 48V DC.
PWR: Power LED, a steady green
light indicates that the PoE system has
detected the PD or PoE Splitter and
the power adapter is working properly.
