MikroTik SXT LTE kit-US: 3G/4G/LTE CPE Instruction Manual

1. Introduction and Overview

The MikroTik SXT LTE kit-US (product code RBSXTR&R11e-LTE-US) is a compact outdoor Customer Premises Equipment (CPE) designed for remote locations requiring cellular network connectivity. This device integrates a professional LTE chip and a high-gain antenna to provide reliable internet access, even in areas where standard cell phones may struggle to receive a signal.

It features two Ethernet ports, with the second port offering Power over Ethernet (PoE-out) functionality, allowing it to power another compatible device. The unit operates with a 24V power supply (included) but supports a wide input voltage range of 12-57V, and 18-57V with PoE-Out, adhering to 802.3af/at standards.

Equipped with a high-quality 3G/4G/LTE Category 4 modem, the SXT LTE kit-US delivers speeds of up to 150 Mbit/s for downlink and 50 Mbit/s for uplink. For enhanced reliability, it includes two Micro SIM slots for a backup link. This specific model supports LTE bands 2, 4, 5, and 12, which are commonly used by mobile operators in the United States, Canada, and Latin America.

3. Setup

Follow these steps for proper installation and initial setup of your MikroTik SXT LTE kit-US:

1. Physical Installation: The SXT LTE kit-US is designed for outdoor use. Mount the device in a location with optimal cellular signal reception, typically on a pole or mast. Ensure the device is securely fastened using the provided mounting bracket. The device's directional antenna requires careful aiming towards the nearest cellular tower for best performance.
2. SIM Card Insertion: Locate the two Micro SIM slots on the device. Insert your activated Micro SIM card(s) into the slots. Ensure they are correctly oriented and seated firmly. The device supports two SIM cards for redundancy or backup links.
3. Power Connection: Connect an Ethernet cable from the SXT LTE device to the PoE injector. Then, connect the included 24V power supply to the PoE injector. Finally, connect another Ethernet cable from the PoE injector's LAN port to your router or computer. The device will power on automatically.
4. Initial Configuration: Access the device's configuration interface via a web browser or MikroTik's WinBox utility. The default IP address and login credentials can typically be found in the quick start guide or on the device itself. The device runs on RouterOS, which offers extensive configuration options. For basic internet access, the default configuration may suffice, but advanced network settings will require familiarity with RouterOS.

4. Operating Instructions

Once installed and configured, the SXT LTE kit-US operates as a cellular modem and router, providing internet connectivity to your local network.

• Cellular Connectivity: The device automatically connects to the cellular network using the inserted SIM card(s). The integrated high-gain antenna optimizes signal reception.
• Data Transmission: It utilizes a 3G/4G/LTE Category 4 modem, supporting downlink speeds up to 150 Mbit/s and uplink speeds up to 50 Mbit/s.
• Ethernet Ports: The device has two Ethernet ports. The first port is for primary network connection and power input (PoE-in). The second port offers PoE-out functionality, allowing you to power another PoE-compatible device, such as a wireless access point or IP camera, directly from the SXT LTE kit-US.
• Monitoring: You can monitor the device's status, signal strength, and data usage through the RouterOS web interface or WinBox. Regular monitoring helps ensure optimal performance.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your SXT LTE kit-US.

• Firmware Updates: Periodically check the MikroTik website for the latest RouterOS firmware updates. Updating the firmware can provide new features, performance improvements, and security patches. Be aware that updates may apply to the router part or the LTE modem part, and it's important to follow MikroTik's update procedures carefully.
• Physical Inspection: For outdoor installations, regularly inspect the device and its mounting hardware for any signs of wear, corrosion, or damage from weather elements. Ensure all cable connections are secure and free from moisture.
• Cleaning: Keep the device's exterior clean from dust, dirt, and debris. Use a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
• Environmental Considerations: Ensure the device is operating within its specified temperature and humidity ranges to prevent damage.

6. Troubleshooting

If you encounter issues with your SXT LTE kit-US, refer to the following troubleshooting tips:

• No Internet Connection:
  • Verify the SIM card is correctly inserted and activated with your mobile operator.
  • Check the cellular signal strength indicators on the device or via the RouterOS interface. If the signal is weak, adjust the device's aiming towards the cellular tower.
  • Ensure the device is receiving power and the Ethernet cables are securely connected.
  • Confirm that your mobile operator supports LTE bands 2, 4, 5, or 12, as these are the bands supported by this model in the US, Canada, and Latin America.
  • Check RouterOS configuration for any misconfigurations, especially related to APN settings or firewall rules.
• Slow Speeds:
  • Optimize antenna aiming for the strongest possible signal.
  • Check for network congestion during peak hours.
  • Ensure your data plan supports the desired speeds.
  • Verify that the device's firmware is up to date.
• Device Not Powering On:
  • Confirm the 24V power supply is connected and functional.
  • Check the Ethernet cable connection between the device and the PoE injector.
  • Ensure the power outlet is working.
• RouterOS Access Issues:
  • Ensure your computer is on the same network segment as the MikroTik device.
  • Try accessing via WinBox if the web interface is unresponsive.
  • If you have forgotten your password, a hard reset may be necessary (refer to MikroTik documentation for specific reset procedures, as this will erase all configurations).
