5. Impostazione

5.1 Montaggio su rack

1. Fissare le staffe di montaggio su rack fornite ai lati dello switch utilizzando le viti in dotazione.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Collegamento di alimentazione

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Collegare l'altra estremità del cavo di alimentazione a una presa elettrica con messa a terra.
3. Ensure the power supply is properly seated and secured.

5.3 Connessioni di rete

• Connect Ethernet cables from your network devices (computers, access points, IP phones) to the 48 Gigabit Ethernet ports on the front panel.
• For uplink connectivity, install the appropriate uplink module (if not pre-installed) and connect fiber or copper cables to your core network or other switches.
• For stacking, connect StackWise-480 cables between the stack ports of multiple Catalyst 9300 switches.

5.4 Configurazione iniziale

1. Connect a computer to the console port using the provided console cable.
2. Use a terminal emulation program (e.g., PuTTY, Tera Term) with settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
3. Power on the switch. The boot process will display messages on the console.
4. Follow the on-screen prompts to perform initial setup, including setting the hostname, IP address, and administrative passwords.

6. Funzionamento dell'interruttore

6.1 Accensione/spegnimento

To power on the switch, ensure the power cord is securely connected to a live outlet. The switch will automatically begin its boot sequence. To power off, disconnect the power cord. For graceful shutdown, use the appropriate command-line interface (CLI) commands.

6.2 Indicatori LED

Monitor the LED indicators on the front panel to understand the switch's operational status:

• LED di sistema: Indicates overall system health (e.g., green for normal, amber for warning, red for critical).
• LED PoE: Shows the status of Power over Ethernet (e.g., green for active PoE, amber for fault).
• LED di stato della porta: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Collegamento dei dispositivi

Connect network devices to the Gigabit Ethernet ports. For devices requiring power, ensure they are PoE-compatible and the switch's PoE budget is sufficient. The switch automatically detects and provides power to PoE-enabled devices.

6.4 Funzionalità avanzate

The Cisco Catalyst 9300 supports advanced features such as:

• StackWise Virtual: For creating a single logical switch from multiple physical switches.
• Cisco IOS XE: A modern, programmable operating system for advanced network management and automation.
• Funzionalità di sicurezza: Integrated security for threat detection and mitigation.

7. Manutenzione

7.1 Pulizia

Periodically clean the exterior of the switch with a soft, dry, lint-free cloth. Do not use liquid or aerosol cleaners directly on the switch. Ensure ventilation openings are free from dust and obstructions.

7.2 Aggiornamenti firmware

Controllare regolarmente il supporto Cisco website for the latest firmware updates. Applying updates can improve performance, add new features, and address security vulnerabilities. Follow Cisco's official documentation for firmware upgrade procedures.

7.3 Considerazioni ambientali

Maintain the operating environment within specified temperature and humidity ranges. Ensure proper airflow around the switch to prevent overheating. Refer to the specifications section for environmental limits.

8. Risoluzione Dei Problemi

8.1 Nessun potere

• Verificare che il cavo di alimentazione sia collegato saldamente sia all'interruttore sia a una presa elettrica funzionante.
• Check the power supply module(s) are properly seated.
• Provare la presa elettrica con un altro dispositivo.

8.2 Nessuna connettività di rete

• Check the port status LEDs for a link light. If no link, try a different cable or port.
• Verificare che il dispositivo collegato sia acceso e funzioni correttamente.
• Ensure correct VLAN and IP configurations on the switch and connected devices.

8.3 Dispositivo PoE non acceso

• Confirm the connected device is PoE-compatible (IEEE 802.3af/at).
• Check the PoE LED on the switch for any fault indications.
• Verify the switch's total PoE budget is not exceeded.
• Ensure PoE is enabled on the specific port via CLI.
