Componenti:

• Unità Centrale: Houses the wireless electronics, CPU, RAM, storage, and Ethernet port.
• Integrated Antenna Feed: Part of the central unit, connected directly to the wireless electronics.
• Grid Reflector: The large mesh dish that focuses the radio signal.
• Staffa di fissaggio: For attaching the device to a pole or mast.
• Porta Ethernet: 10/100 Mbps port for data and Passive PoE input.

4. Configurazione e installazione

4.1 Contenuto della confezione

Please verify that all components are present in your package. Refer to the product packaging for a detailed list of included items, which typically includes the LHG 5 unit, mounting kit, and a PoE injector (may vary by region/bundle).

4.2 Montaggio del dispositivo

The LHG 5 is designed for outdoor pole mounting. Ensure the mounting surface is stable and capable of supporting the device, especially in windy conditions. The grid design helps reduce wind load.

1. Assemble the grid reflector according to the diagrams provided in the separate assembly guide (if applicable).
2. Attach the central unit to the assembled grid reflector.
3. Secure the mounting bracket to the back of the central unit.
4. Mount the entire assembly to a pole or mast using the provided U-bolts or clamps. Ensure the device is oriented correctly for optimal signal alignment.
5. Tighten all fasteners to prevent movement due to wind or vibration.

4.3 Alimentazione del dispositivo

The LHG 5 supports Passive Power over Ethernet (PoE). It requires a PoE injector or a PoE-capable switch to provide power and data over a single Ethernet cable.

1. Connect one end of an Ethernet cable to the LHG 5's Ethernet port.
2. Connect the other end of the Ethernet cable to the "PoE" or "Data+Power" port of a Passive PoE injector.
3. Connect a standard Ethernet cable from the "LAN" or "Data" port of the PoE injector to your network switch or computer.
4. Plug the PoE injector's power adapter into an electrical outlet. The device will power on.

Nota: Ensure the PoE injector provides the correct voltage for the LHG 5 (typically 10-30V DC, refer to device label for exact requirements).

5. Utilizzo del dispositivo

The MikroTik LHG 5 runs on MikroTik's RouterOS operating system. Initial configuration is typically done via a web navigatore (WebFig) or a dedicated utility (WinBox).

5.1 Configurazione iniziale

1. After powering on, connect your computer directly to the LAN port of the PoE injector.
2. Aprire un web browser and navigate to the default IP address of the device (commonly 192.168.88.1, refer to MikroTik documentation for specifics).
3. Log in using the default credentials (usually admin with no password).
4. Follow the on-screen prompts or refer to the RouterOS documentation for detailed configuration steps, including setting up wireless modes (Access Point, Station), IP addresses, and security settings.

5.2 Point-to-Point (PtP) Links

For PtP links, two LHG 5 devices are typically used, one configured as an Access Point (AP) and the other as a Station (Client). Ensure clear line-of-sight between the two devices for optimal performance.

5.3 CPE Usage

When used as CPE, the LHG 5 acts as a client device connecting to a central Access Point. Configure it in Station mode and scan for available networks.

6. Manutenzione

• Pulizia: Periodically inspect the grid antenna for dirt, debris, or ice accumulation. Gently clean with a soft cloth and mild detergent if necessary. Do not use abrasive cleaners.
• Aggiornamenti del firmware: Controllare regolarmente il MikroTik website for firmware updates for RouterOS. Keeping the firmware updated ensures optimal performance, security, and access to new features.
• Ispezione fisica: Annually inspect mounting hardware for corrosion or loosening. Ensure all cables are securely connected and free from damage.

7. Risoluzione Dei Problemi

7.1 Il dispositivo non si accende

• Verify the PoE injector is properly connected to a working power outlet.
• Check the Ethernet cable between the PoE injector and the LHG 5 for damage or improper connection.
• Ensure the PoE injector is compatible with Passive PoE and provides the correct voltage.

7.2 Nessuna connettività di rete

• Confirm the Ethernet cable from the PoE injector's LAN port to your network is functional.
• Check the device's IP configuration. Ensure your computer is on the same subnet for initial access.
• Verify wireless settings (SSID, security, frequency) are correctly configured for your network.
• Ensure clear line-of-sight and proper antenna alignment for wireless links.

7.3 Poor Wireless Performance

• Check antenna alignment. Even slight misalignment can significantly reduce signal strength.
• Ensure there are no obstructions (trees, buildings) in the line-of-sight.
• Scan for interference from other 5GHz devices in the area and adjust channels if necessary.
• Verify RouterOS settings for transmit power and data rates.
