• RJ-45 Console Port: Used for initial configuration and management via a terminal emulator.

5. Configuració

Follow these steps to set up your Cisco Catalyst 3560G-24PS-S switch.

5.1 Muntatge de l'interruptor

El commutador es pot col·locar sobre un escriptori o muntar-se en un rack d'equips estàndard de 19 polzades.

• Ubicació d'escriptori: Attach the four rubber feet to the bottom of the switch. Ensure the switch is placed on a flat, stable surface with adequate ventilation.
• Muntatge en bastidor: Use the provided 19-inch rack-mounting brackets and screws to secure the switch into a standard equipment rack. Ensure proper airflow within the rack.

5.2 Connexió de potència

1. Assegureu-vos que l'interruptor estigui apagat.
2. Connect the supplied AC power cord to the power connector on the rear panel of the switch.
3. Connecteu l'altre extrem del cable d'alimentació a una presa de corrent amb connexió a terra.
4. The switch will power on automatically. Observe the system LED for status.

5.3 Connexió de cables de xarxa

1. Connect standard RJ-45 Ethernet cables from your network devices (computers, IP phones, wireless access points) to the 10/100/1000Base-T ports on the switch's front panel.
2. For uplink connections, insert appropriate SFP transceivers into the SFP slots and connect fiber optic or copper cables as required.
3. Ensure cables are securely seated. The port LEDs will indicate link status and activity.

5.4 Accés a la configuració inicial

To perform initial configuration, connect a computer to the switch's console port using the provided RJ-45-to-DB-9 adapter cable and 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

6. Funcionament de l'interruptor

Once powered on and connected, the Cisco Catalyst 3560G-24PS-S switch operates as a Layer 2/3 network device.

6.1 Funcionalitat d'alimentació a través d'Ethernet (PoE)

The switch's 24 ports support IEEE 802.3af and Cisco prestandard PoE, automatically detecting and providing power to connected PoE-compatible devices such as IP phones, wireless access points, and IP cameras. The PoE status LEDs indicate power delivery status for each port.

6.2 Serveis de xarxa

The switch supports a range of intelligent network services:

• Qualitat de servei (QoS): Prioritizes network traffic to ensure performance for critical applications.
• Llistes de control d'accés (ACL): Filtra el trànsit de xarxa segons regles definides per a una seguretat millorada.
• Limitació de tarifes: Controls the maximum bandwidth for specific traffic flows.
• Enrutament IP: Provides Layer 3 routing capabilities for inter-VLAN communication and network segmentation.

Detailed configuration of these features is performed via the command-line interface (CLI) or a network management system, as described in the Cisco documentation.

7. Manteniment
