4. Configuració

4.1 Instal·lació física

1. Col·locació: Place the device on a flat, stable surface or mount it in a rack using appropriate mounting hardware (sold separately). Ensure adequate ventilation around the unit.
2. Connexió d'alimentació: Connect the power adapter to the DC jack on the device and then to a suitable power outlet. The device supports Passive PoE input on Ethernet port 1 (10-57V).
3. Connexions de xarxa:
   • Connect your network devices (computers, servers, other switches) to the Gigabit Ethernet ports using standard Ethernet cables.
   • For fiber optic connections, insert compatible SFP modules into the SFP cages and connect fiber optic cables.

4.2 Accés inicial

The device comes pre-configured with a default IP address (typically 192.168.88.1) and a default username (admin) with no password. You can access the device via:

• Web Navegador (WebFiga): Obre a web browser and navigate to the device's IP address.
• WinBox Utility: Download and run the WinBox utility from the MikroTik website. It will discover the device by MAC address or IP address.
• Serial Console: Connect a serial cable to the console port (if available on your model) and use a terminal emulator.

Important: For security, change the default administrator password immediately after initial access.

5. Funcionament

The CRS112-8G-4S-IN operates on MikroTik's RouterOS, a powerful and flexible operating system. It combines Layer 2 (switching) and Layer 3 (routing) functionalities.

5.1 Basic Switching Configuration

The device's Ethernet and SFP ports are part of a switch chip. Basic switch configurations, such as VLAN tagging, port isolation, and port mirroring, can be managed through the Canvia menu in RouterOS. Ports can also be removed from the switch configuration and used for routing purposes if desired.

5.2 Routing Capabilities

As a Cloud Router Switch, the CRS112-8G-4S-IN can perform routing functions. All Layer 3 operations are handled by the CPU. While capable of advanced routing protocols, performance for high-throughput routing will be limited by the CPU's capacity (400 MHz nominal frequency).

5.3 RouterOS Documentation

For detailed configuration guides and advanced features, refer to the official MikroTik RouterOS documentation available on the MikroTik weblloc (wiki.mikrotik.com). This resource provides comprehensive information on all aspects of RouterOS configuration.

6. Manteniment

6.1 actualitzacions de microprogramari

Regularly update RouterOS firmware to ensure optimal performance, security, and access to new features. Firmware updates can be performed via the RouterOS interface (WebFig or WinBox) by downloading the latest package from the MikroTik weblloc.

6.2 Neteja

Keep the device clean and free from dust. Use a soft, dry cloth for cleaning the exterior. Do not use liquid cleaners or aerosols. Ensure ventilation openings are not obstructed.

6.3 Consideracions ambientals

Operate the device within the specified temperature range (up to 70 Degrees Celsius). Avoid exposing the device to direct sunlight, high humidity, or extreme temperature fluctuations.

7. Solució De Problemes

This section addresses common issues you might encounter with your CRS112-8G-4S-IN.

• El dispositiu no s'encén: Verify the power adapter is correctly connected to the device and a working power outlet. Check if the power LED is illuminated.
• Cannot access RouterOS: Ensure your computer is on the same subnet as the device's default IP (192.168.88.1). Check network cable connections. Try accessing via MAC address using WinBox. If the IP address was changed and forgotten, a hard reset might be necessary (refer to MikroTik documentation for reset procedures).
• No network connectivity on a port: Check the cable connection. Verify the link LED for the port is active. Ensure the port is enabled and correctly configured in RouterOS (e.g., not disabled, correct VLAN settings).
• Mal rendiment: For routing tasks, CPU utilization might be high. Check system resources in RouterOS. For switching, ensure proper VLAN configuration and avoid loops.

For more advanced troubleshooting, consult the MikroTik Wiki or contact technical support.
