5. Configuración

5.1 Montaxe en rack

1. Fixe os soportes de montaxe en bastidor fornecidos aos laterais do conmutador usando os parafusos incluídos.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Conexión de alimentación

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Conecte o outro extremo do cable de alimentación a unha toma eléctrica conectada a terra.
3. Asegúrate de que a fonte de alimentación estea correctamente asentada e fixada.

5.3 Conexións de rede

• 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 Configuración inicial

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. Funcionamento do interruptor

6.1 Encendido/apagado

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 Indicadores LED

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

• LED do sistema: Indica o estado xeral do sistema (por exemplo, verde para normal, ámbar para aviso, vermello para crítico).
• LED PoE: Shows the status of Power over Ethernet (e.g., green for active PoE, amber for fault).
• LED de estado do porto: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Conexión de dispositivos

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 Funcións avanzadas
