Installation and Startup
Note: Depending on where you are installing the LX40, you may want to mount the router before connecting the antenna, cables and power.
Step 1—Insert the SIM Card
If the SIM card has not already been installed, insert the SIM card into the router before connecting any external equipment or power to the router.
To install the SIM card:
1.Remove the SIM card cover. Press the tab with a screwdriver while sliding the cover upwards.
2.Orient the SIM card as shown in Figure 2-1 (with the gold contacts facing down).
3.Gently slide the SIM card into the slot until it clicks into place.
To remove the SIM card, press the SIM card in, and release it. Gently grip the SIM card and pull it out.
4.Replace the SIM card cover.
Note the orientation of notched corner for proper SIM card alignment.

Figure 2-2: Mounting and Grounding the LX40
Grounding the LX40
Sierra Wireless strongly recommends that you always ground the chassis using the grounding point shown in Figure 2-3.
For DC installations (with a fixed “system” ground reference), Sierra Wireless recommends grounding the LX40 chassis to this system ground reference.
To ensure a good grounding reference, connect one end of a short 18 AWG or larger gauge wire with a ring terminal connector to the ground terminal on the LX40 and connect the other end to your main grounding point.
The ground terminal comes with an M2.5 × 6 mm screw. You can use a longer
M2.5 screw if the terminal connector on your ground wire requires one.
Note: Do not overtighten the grounding screw. Tighten to a maximum torque of 0.4 kg/cm.

To mount the LX40 permanently to any surface or if you are mounting the LX40 on a DIN rail, order an LX40 mounting bracket kit (P/N 6001221) from Sierra Wireless. The kit contains:
•Mounting bracket
•DIN rail clip (35 mm EN 50022) (see DIN Rail Mount on page 15)
•Screws for attaching the DIN rail clip to the mounting bracket
To mount the LX40 on a flat surface:
1.Attach the bracket to the mounting surface, using the attachment points shown in Figure 2-4.
Holes are Ø 4.3 mm (M4 compatible; use hardware appropriate for your mounting surface)
Figure 2-4: Mounting Bracket, showing attachment points
2.Snap the LX40 onto the bracket (see Figure 2-5 on page 14).
a.Angle the LX40 with the antenna connectors downwards, and fit the bracket clasps against the indentations on the end of the LX40. The raised edge of the bracket should match the rounded corner of the LX40.
b.Bring the other end of the LX40 down onto the bracket and snap it into place. The bracket clasps should fit into the indentations on the end of the LX40.

Mounting in a High Vibration Environment
Note: If you are mounting the LX40 in a high vibration area, Sierra Wireless strongly recommends using two nylon cable ties to secure the LX40 on the bracket.
1.Thread the ties beneath the bracket.
2.Wrap the ties around the LX40, using the notches in the LX40 casing (see Figure 2-5) to align the ties.
3.Tighten and secure the ties around the LX40 and trim off the excess length of the ties.

Installation and Startup
DIN Rail Mount
You can mount the LX40 on a DIN rail in a vertical orientation, with the antenna connectors pointing up or down.
Note: The DIN rail mounting clip should only be used on a horizontally-mounted DIN rail.
Ensure spring clip is at the bottom
To mount the LX40 with antenna connectors pointing down, rotate the DIN clip 180 degrees before attaching.
Figure 2-6: Attaching the DIN Rail Mounting Clip
To attach the LX40 to a horizontally mounted DIN rail:
Note: Before installing the LX40 in its final location, you may want to install the SIM card (see page 11), attach antennas (see page 16), power up the device (see page 17) and test the network connectivity (see page 28). After a successful test, you can remove cables and antennas and proceed with the procedure below.
1.Secure the LX40 in the mounting bracket, as described on page 13.
2.Use the screws provided to attach the DIN clip to the bracket. Attach the clip in the direction to achieve the desired position for the LX40. In the final orientation, the spring clip should be at the bottom. Torque the screws to a maximum of 1.1 N-m (10 in-lb.).
3.Attach the DIN rail clip to a horizontal DIN rail, with the spring clip at the bottom.

Note: Take extra care when attaching the antennas to the SMA connectors. Finger tight (approximately 0.6– 0.8 Nm 5–7 in-lb.) is sufficient and the max torque should not go beyond
1.1 Nm (10 in-lb.).
Step 3—Connect the Antennas
Warning: This router is not intended for use close to the human body. Antennas should be at least 8 inches (20 cm) away from the operator.
The LX40 has two SMA female antenna connectors:
•Cellular antenna connector: Primary receive and transmit antenna connector
•Cellular Diversity antenna connector: LTE MIMO and 3G Diversity
The AirLink LX40 with Wi-Fi also has:
•One reverse polarity SMA male connector for the Wi-Fi antenna. Sierra Wireless recommends cabling out the antenna.
The LX40 supports 2.4 GHz (2400–2500 MHz) and 5GHz
(4900–5900 MHz) Wi-Fi bands. See Wi-Fi Channels Supported on page 39 for more information.
For regulatory requirements concerning antennas, see Maximum Antenna Gain on page 48.
Note: The antenna should not exceed the maximum gain specified in RF Exposure on page 48. In more complex installations (such as those requiring long lengths of cable and/ or multiple connections), you must follow the maximum dBi gain guidelines specified by the radio communications regulations of the Federal Communications Commission (FCC), Industry Canada, or your country’s regulatory body.
To install the antennas:
1.Connect the cellular antenna to the SMA cellular antenna connector.
Mount the cellular antenna so there is at least 20 cm between the antenna and the user or bystander.
2.Connect a second antenna to the SMA diversity antenna connector.
For 3G networks, the second antenna operates as a diversity antenna, providing a second receive path.
For 4G networks, the second antenna operates as a MIMO antenna, providing a second receive path and a second transmit path.
3.For Wi-Fi-capable routers, connect the Wi-Fi antenna to the SMA Wi-Fi connector.
Note: If the antennas are located away from the router, keep the cables as short as possible to prevent the loss of antenna gain. Route the cables so that they are protected from damage and will not be snagged or pulled on. There should be no binding or sharp corners in the cable routing. Excess cabling should be bundled and tied off. Make sure the cables are secured so their weight will not loosen the connectors from the router over time.

Recommended Antenna Separation
The recommended antenna separation is related to the band frequency/ wavelength. To accommodate the shortest frequency/longest wavelength band supported by the LX40, Sierra Wireless recommends a minimum antenna separation of 214 mm for best results, and if necessary, a separation of 107 mm for acceptable results.

Step 4—Connect the Data Cables
The LX40 has the following ports for connecting data cables:
•USB (Micro-AB)
•Ethernet (RJ-45)—Use a Cat 5e or Cat 6 Ethernet cable
Step 5—Connect the Power
The AirLink LX40 comes with a 3 meter (10 ft.) DC power cable. You can also purchase an optional AC adapter.
The LX40 can also use Power over Ethernet. An Ethernet cable connected to a compatible1 network switch or router can supply power to the LX40. No connection to the LX40 power connector (see Figure 2-8 on page 19) is required.
Warning: Electrical installations are potentially dangerous and should be performed by personnel thoroughly trained in safe electrical wiring procedures.
