2.3 PoE & LAN
The EZR33L router takes electric power from the PoE injector. It can also receive WAN or provides a LAN Ethernet connection through the PoE injector.
Comply with 802.3af/at PoE standard, the outdoor 4G router uses a LAN cable to transmit both DC power and Ethernet data. A 48Volt standard PoE injector and 10-meter outdoor-grade LAN cable are included in the package.

Connect to PoE Power

Please refer to the image and follow the below steps to connect the EZR33L router to the PoE injector.
Connect EZR33L 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 of the barrel connector.
2 - Take one end of the LAN cable through the cap.
3 - Put 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 in the clockwise direction 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 until set up all the below steps (to 3.3).

Notes

Exchange AC Plug on PoE Injector

To exchange the AC plug on the PoE injector, press and hold the Push button, then push the AC plug upward to take it off. Then install another AC plug on it.

Exchange LAN Cable

A 10-meter outdoor grade LAN cable is included in the package. You can use a max 50-meter LAN cable. Use Cat5 or higher-grade LAN cable and make sure it's the TIA/EIA568B wiring. Please refer to the below image. An outdoor-grade LAN cable is recommended to use in the outdoor environment.
There will be a distinct attenuation on the Ethernet signal when the LAN cable is longer than 50-meter. You can use a PoE extender to reduce the attenuation on a longer LAN cable.

PoE Ethernet Connection

There are two RJ45 ports on the PoE injector. The PoE port outputs 48Volt 0.5Amps DC power to boot up the 4G router.
After the 4G router connected to the mobile network, we can connect a computer, another router, or network switch to the LAN port on the PoE injector and get an Ethernet connection.
Make sure the computer or another router turned on DHCP client mode. Then they could automatically obtain a local IP address and connect to the internet.

Alternative Power

i. PoE Switch

You can use an IEEE802.3af/at standard PoE switch to power up the 4G router. Connect the 4G router to one of the PoE ports on the PoE switch.
To receive the internet signal provided from the Uplink port on the PoE switch, please bind eth1 to the WAN interface (the same as the AP mode on 3.3.4).

ii. 12Volt Power

We can boot up the EZR33L router with a wide range of 9~48Volt DC power. Use the DC plug to connect to the DC socket on the motherboard. The PoE gland can take an extra DC power cable. The suggested DC power current is 12Volt 1.5Amps.
‌ If both DC power and PoE power are connected, the EZR33L router will use the firstly connected power source. If one of them cuts off power, the router will switch to another power source seamlessly.
