4.2. Inserting SIM Cards

The device has two Micro SIM slots for primary and backup cellular connections.

1. Open the access panel on the rear of the device.
2. Carefully insert your Micro SIM cards into the designated slots until they click into place.
3. Close the access panel securely to maintain weather resistance.

4.3. Powering the Device

The SXT LTE6 kit supports Power over Ethernet (PoE) and comes with a 24V power supply.

1. Connect an Ethernet cable from the PoE injector's 'PoE' port to the primary Ethernet port on the SXT LTE6 unit.
2. Connect the 24V power supply to the PoE injector.
3. Connect another Ethernet cable from the PoE injector's 'LAN' port to your router or computer.

The device supports a full voltage range of 18-57V and is 802.3af/at compliant.

5. Operation and Configuration

The SXT LTE6 kit runs on MikroTik's RouterOS, offering extensive configuration options. Initial setup typically involves accessing the device's web interface or using the WinBox utility.

5.1. Initial Configuration

1. Connect your computer to the LAN port of the PoE injector.
2. Open a web browser and navigate to the device's default IP address (refer to the Quick Start Guide or MikroTik documentation). Alternatively, use the WinBox utility for advanced configuration.
3. Log in using the default credentials. It is highly recommended to change the default password immediately.
4. Configure the Access Point Name (APN) settings for your cellular carrier. This is crucial for establishing an internet connection. Consult your carrier for the correct APN.
5. Verify cellular signal strength using the device's interface or LED indicators. Adjust the device's orientation if necessary to optimize signal.

5.2. Advanced Features

• Carrier Aggregation: The CAT6 LTE modem supports carrier aggregation, allowing the device to utilize multiple LTE bands simultaneously for increased bandwidth and speed.
• Dual SIM for Backup: Configure the device to automatically switch to the secondary SIM card if the primary cellular connection fails, ensuring high availability.
• PoE-out Functionality: The second Ethernet port can provide Power over Ethernet to another compatible device, simplifying installations.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your SXT LTE6 kit.

• Firmware Updates: Periodically check the MikroTik website for the latest RouterOS firmware and modem firmware updates. Keeping the device updated ensures access to new features, performance improvements, and security patches.
• Physical Inspection: Annually inspect the device and its mounting hardware for any signs of wear, corrosion, or damage. Ensure all cables are securely connected and free from damage.
• Cleaning: Gently clean the exterior of the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Ensure the access panel is always sealed to prevent moisture ingress.

7. Troubleshooting

If you encounter issues with your SXT LTE6 kit, refer to the following common troubleshooting steps:

• No Internet Connection:
  • Verify SIM card insertion and activation with your carrier.
  • Check APN settings in the device configuration.
  • Ensure adequate cellular signal strength. Relocate or reorient the device if signal is weak.
  • Confirm power supply and Ethernet cable connections.
• Slow Speeds:
  • Check signal strength and quality (RSRP, RSRQ, SINR values in RouterOS).
  • Ensure carrier aggregation is active and utilizing multiple bands if available.
  • Consider network congestion in your area.
• Device Not Powering On:
  • Verify the power supply is connected and functional.
  • Check the PoE injector and Ethernet cable for damage.
• Difficulty Accessing Configuration Interface:
  • Ensure your computer's network settings are compatible with the device's default IP range.
  • Try resetting the device to factory defaults (refer to MikroTik documentation for the specific procedure).

For more detailed troubleshooting, consult the MikroTik Wiki and community forums.
