SIM Card & PoE

Insert a SIM card and connect to the PoE power to boot up the outdoor 4G router.

Insert SIM Card

The outdoor 4G router requires insert at least one SIM card to connect to the mobile internet networks. The SIM card is not included with the router.

Use a Nano SIM card (12.3x8.8mm) on the 4G router. If it's a new SIM card, please follow the instructions from the mobile carrier to activate the SIM card.

If the 4G router cannot detect the SIM card or gets the error message "SIM card unavailable," firstly verify if the SIM card is inserted correctly. Secondly, please check if the SIM card is clean, especially on the golden contacts.

Please always turn off the power while inserting or removing the SIM card.

Step by Step

Use the SIM pin to push the pinhole gently until the SIM card holder pops out.
Put the primary SIM card in the first slot. Make sure notch in the inside direction and pins face down. There is only one way to settle the Nano SIM card into the SIM cardholder.
Carefully reposition the SIM card holder in the slot and push it back gently.

i. Please use an unlocked and activated SIM card.

ii. A few parts of the SIM card holder (near the handle) will stay outside. It's a normal situation. You can ignore it. ‌

iii. Please insert a SIM card in the SIM#1 slot on the SIM card holder unless you choose to use secondary SIM#2 on the mobile interface.

iiii. The 4G router can work well with a single SIM card. You can also insert an extra SIM card as a backup connection. To activate the backup connection, please enable the auto-switch option on the mobile interface.

Signal Strength

Good 4G LTE mobile signal quality is fundamental to getting a stable and fast internet connection over the mobile network.

A "Fair" signal level is needed for the 4G router (refer to the chart below), which equals approximately 2-bar 4G LTE signals on a mobile phone.

You can run a basic test on a mobile phone. Insert the SIM card used on the router on a mobile phone. Go outdoors with a mobile phone. Disable the Wi-Fi connection and check the network type and signal bars. Then, choose a location with a strong and stable 4G-LTE signal reception.

The numerical value of 2G and 3G networks is RSSI standard.

The LTE network is RSRP standard. RSRP is Reference Signal Receive Power.

The signal values are negative numbers. The number that is closer to zero means a stronger signal. For example, -90dB is stronger than -100 dB.

PoE LAN

The outdoor router takes electric power from the PoE injector. It can also receive WAN or provide a LAN Ethernet connection through the PoE injector.

Complying 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 EZR33T router to the PoE injector.

Step by step

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 inside the barrel connector.
Take one end of the LAN cable through the cap.
Put the LAN cable through the barrel screw and plug in the PoE & LAN port on the motherboard.
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.
Turn the cap in the clockwise direction to tighten it on the barrel screw.
Connect another end of the LAN cable to the PoE port on the PoE injector.
Connect the AC plug on the PoE injector to an electrical outlet until all the steps below are set up.

Remarks:

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 ensure it's the TIA/EIA568B wiring. Please refer to the below image. An outdoor-grade LAN cable is recommended for use in the outdoor environment. 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 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 is 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 turns on DHCP client mode. Then, they could automatically obtain a local IP address and connect to the internet.

Alternative Power

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.

12Volt Power

We can boot up the outdoor router with a 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 outdoor router will use the first connected power source. The router seamlessly switches to another power source if one cuts off power.

Indicators & Enclosure

Indicators

There are four indicators on the outdoor 4G router. From top to bottom, the left sides are system & Wi-Fi, and the right side is SIM1 & SIM2. Below are the indicator descriptions.

Indicator	Status	Description
System	Green	This light indicates that the router is receiving power. If it's lit solid green, then the router has booted successfully.
	Flash	The router system is booting up. The system indicator flashes while resetting or flashing the firmware.
	Off	No light at all indicates that the router is not receiving power. Check the PoE socket connected to the motherboard and check the PoE adapter. You might need to test an alternate power socket if the router doesn't power on.
Wi-Fi	Green	This light indicates that the modem is sending a Wi-Fi signal. You can see and connect to the Wi-Fi network if the light is green.
	Flash	If you are connected to the Wi-Fi hotspot, it will flash green to indicate data going to and from the router. If the router is connected to another Wi-Fi hotspot (Wi-Fi relay), it will also flash because it has the data flow.
	Off	If it's off, your router no longer sends a Wi-Fi signal. You can log in to the router admin and turn on the Wi-Fi master hotspot.
SIM1/2	Green	These lights indicate which SIM card the router is using. It uses the SIM1 by default. You can change to use SIM2 on the router admin.

Close the Enclosure

Close the lid & press it with your hand. Then, use the hexagon end on the T-wrench to tighten four pieces of bolts on the lid. After closing the enclosure, please review and ensure no gap after tightening the screws!

Install Antennas

The outdoor router use MIMO antennas on both mobile and Wi-Fi connections.

There are four antenna sockets on the outdoor router. Firstly, find the embossed numbers #1~6 on the enclosure.

#1 & 3 on the top side are for 4G antennas. #1 is the 4G main input port.

#4 & 6 on the bottom side are for the 2.4G Wi-Fi antennas.

‌The antennas have 4G or 2.4G text engraved on one side of the hexagon connector.

Put 4G and 2.4G antennae on the corresponding socket and turn the hexagon part clockwise to tighten the antenna on the router. Make sure the antennas are installed tightly.

While installing the antenna, put the router device in a vertical or horizontal direction to avoid bending the pins in the antenna connector.

The default Omni antennas are polarized vertically. Please always use the antenna in a vertical direction.

Adjust the flat side to point towards the cell tower's direction for better performance.

Upgraded Antenna

All of the base antenna connectors are N-female type.

If the 4G RSRP signal strength is below -105dBm, suggest upgrading the 4G antennas to a directional LPDA antenna or MIMO panel 4G antenna and improving the signal reception.

If using the router on an RV or boat, suggest upgrading to FRP or MIMO Omni antennas.

Bracket & Mounting

Use the mounting kit to install the outdoor router on a pole with a diameter of Ø35~50mm.

Choose Location

Firstly, walk around with a mobile phone and check the network type and signal bars. Then, choose a location with the best available signal reception.

Find a pole with a diameter of Ø35~50mm and in a vertical or horizontal direction. The pole is not included in the package.

L-Shape Bracket

Find the M6 standard cross-head screws or lose them from the backside of the enclosure.

Use the cross end of the T-wrench to install the L-shape bracket on the backside of the enclosure.

There are multiple ways to fix the bracket on the enclosure. Make sure the longer side of the bracket is in the rectangular cross direction to the pole.

Install on a Pole

Step-by-Step

Clasp the pole with the U-bolts and holders.
Attach them on either side of the L-shape bracket.
On another side of the bracket, put washers, spring washers, and hex nuts on U-bolts.
Use an M10 spanner to turn the hex nut and tighten the bracket on the pole.

Lightning Protection

Circuit lightning protection is built-in the outdoor router motherboard.

A lightning protection system doesn't attract, repel, or prevent a lightning strike. It provides an efficient grounding network with a low-resistance path to the ground for lightning's electricity.

Lightning Rod

A lightning rod or lightning conductor is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. According to the traditional Franklin design, the router should be installed under a cone of 45 degrees.

Cables & Ground Rod

Use heavy cables that carry lightning current from the rods to the ground. The conductor cable is attached to the router and down to the ground rod.

Use a long, thick, heavy ground rod and bury it deep into the earth. The conductor cable connects to the ground rod to complete a safe path for a lightning discharge around the router.
