# 2.2 PoE Connection
Complying with 802.3af/at PoE standard, the router uses a LAN cable to transmit 52Volt DC power and 1Gbps Ethernet data. A 52Volt 802.3at standard PoE injector and 10-meter outdoor-grade LAN cable are included in the package.
You can use a max 50-meter LAN cable. Suggest using CAT6 or higher-grade LAN cable and ensure it's the TIA/EIA568B wiring. Please refer to the below image.

## **Connect to PoE Injector**
Refer to the above sketch and follow the below steps to connect the router to the PoE injector.
1. **Take apart the PoE gland.**\
Turn the white color cap off from the gland in an anti-clockwise direction.\
Then push out the orange color stopper from the inside direction of the barrel connector.
2. **Take one end of the LAN cable through the cap.**
3. **Put the LAN cable through the barrel screw** and plug in the PoE & LAN port on the motherboard.
4. **Clamp the stopper on the LAN cable** and settle it in the barrel.\
\* The smaller end of the orange color stopper should face the outside.
5. **Turn the cap clockwise** to tighten it on the barrel screw.
6. Connect another end of the LAN cable **to the PoE port on the PoE injector**.
7. Connect the AC plug on the PoE injector to an electrical outlet after finishing all the hardware installation.

#### LAN Cable Distance
There will be a distinct attenuation on the Ethernet signal when the LAN cable is longer than 50 meters. You can use a PoE extender to boost the signals, then use a longer-distance LAN cable.

## PoE Ethernet Connection
The PoE injector has two RJ45 ports, PoE and LAN.\
The PoE port outputs 52Volt 0.5Amps DC power to boot up the router.
**Router Mode --** When the PoE port links to the LAN port on the router, the LAN port on the PoE injector outputs Ethernet from the router. You can connect the LAN port to a computer or another router or switch to extend the mobile internet network system.
**Extender Mode --** When the PoE port links to the WAN port on the outdoor router, the LAN port on the PoE injector acts as the WAN port to input the Internet to the outdoor router. Connect the LAN port on the PoE injector to another internet router, and the outdoor router will work as an extender.
## Alternative Power Sources
### i. PoE Switch
You can replace the default PoE injector with an IEEE802.3at standard PoE switch. On an unmanaged switch, the other terminals linked to the same switch can obtain Internet from the outdoor router.
### ii. 12Volt Power
The DC socket on the outdoor router takes wide range DC power, 9\~52 Volt. The DC socket supports a standard Ø5.5/2.1mm DC plug. The PoE gland can take an extra DC power cable.
If both the DC socket and PoE power are enabled, the router will use the firstly connected power source. If one of them drops, the router will switch to another power source seamlessly.
{% hint style="danger" %}
Do not use an overloaded electrical current on the DC socket! \
The suggested typical DC power is 12Volt 1\~2Amps.
