2.6 Accés a la configuració inicial

To perform initial configuration, connect a console cable from your management workstation to the console port on the router. Use a terminal emulation program (e.g., PuTTY, Tera Term) with the following settings:

• Velocitat de transmissió: 9600
• Bits de dades: 8
• Paritat: cap
• Bits d'aturada: 1
• Control de flux: cap

Upon successful connection, you will be prompted to enter configuration commands.

3. Instruccions de funcionament

3.1 Encès/Apagat

To power on the router, ensure the power cable is securely connected and then switch on the power source. The router will initiate its boot sequence. To power off, safely shut down the system via the command-line interface (CLI) if possible, then disconnect the power source.

Periodically clean the router's exterior with a soft, dry, lint-free cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow. Do not use liquid cleaners or aerosols directly on the device.

4.3 Environmental Monitoring

Monitor the operating environment to ensure it remains within specified temperature and humidity ranges. Extreme conditions can lead to device malfunction or premature failure.

4.4 Còpia de seguretat de la configuració

Regularly back up your router's configuration to an external server or storage device. This allows for quick restoration in case of a system failure or misconfiguration.

5. Solució De Problemes

This section provides solutions to common issues you might encounter with the Cisco ASR 901 router.

5.1 Sense poder

• Verifiqueu que el cable d'alimentació estigui connectat correctament tant al router com a la presa de corrent.
• Check the power source (outlet, power strip, circuit breaker) for functionality.
• Assegureu-vos que la font d'alimentació (si és externa) funcioni correctament.

5.2 Sense connectivitat de xarxa

• Check the LINK/ACT LEDs on the affected ports. If off, verify cable connections and the status of the connected device.
• Ensure the correct network cables (e.g., Ethernet) are used and are not damaged.
• Verify interface configuration in the CLI (show interface comandament).
• Check for IP address conflicts or incorrect subnet masks.

5.3 System Fault (Amber SYS LED)
