5. Configuración

5.1 Instalación física

El conmutador se puede colocar en un escritorio o montar en un rack de equipos estándar de 19 pulgadas.

Colocación de escritorio:

• Coloque el interruptor sobre una superficie plana y estable.
• Ensure adequate space around the switch for ventilation (at least 10 cm on all sides).
• Evite colocar objetos pesados ​​encima del interruptor.

Montaje en bastidor:

• Fije los soportes de montaje en bastidor proporcionados a los lados del conmutador utilizando los tornillos.
• Secure the switch into a standard 19-inch equipment rack using appropriate rack screws.
• Ensure proper grounding of the rack.

5.2 Conexión de la alimentación

1. Conecte un extremo del cable de alimentación a la entrada de alimentación de CA en el panel trasero del conmutador.
2. Conecte el otro extremo del cable de alimentación a una toma eléctrica con conexión a tierra.
3. The switch will power on automatically. Verify the Power LED on the front panel illuminates.

5.3 Conexión de dispositivos de red

• Connect your network devices (computers, servers, access points) to the RJ45 Gigabit Ethernet ports using standard Ethernet cables (Cat5e or higher).
• For fiber optic connections, insert compatible SFP transceivers into the SFP ports and connect fiber optic cables.
• Observe the Link/Act LEDs on the front panel. A solid green LED indicates a valid link, and a blinking LED indicates network activity.

5.4 Acceso a la configuración inicial

The HP 1920S switch can be configured via a web-based graphical user interface (GUI) or a command-line interface (CLI) via a console port (if available on your specific model).

• Web Interfaz gráfica de usuario: Connect a computer to any Ethernet port on the switch. The switch typically obtains an IP address via DHCP or has a default static IP address (refer to the Quick Start Guide for the default IP and login credentials). Open a web navegador e ingrese la dirección IP del conmutador.
• CLI (Consola): Connect a console cable (RJ45-to-DB9) from your computer's serial port to the switch's console port. Use a terminal emulation program (e.g., PuTTY, Tera Term) with appropriate serial port settings (e.g., 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control).

It is highly recommended to change the default login credentials immediately after initial access for security purposes.

6. Operando

Once the switch is physically installed and powered on, you can begin configuring and managing your network.

6.1 Configuración básica de red

• Dirección IP: Configure a static IP address for the switch within your network's subnet for reliable management access.
• VLAN: Create and configure Virtual Local Area Networks (VLANs) to segment your network for improved security and performance. Assign ports to specific VLANs as needed.
• Configuración del puerto: Adjust port speed, duplex mode, and enable/disable ports as required.

6.2 Estado de monitoreo

El web GUI provides various monitoring tools:

• Estado del sistema: View overall device health, CPU usage, and memory usage.
• Estado del puerto: Monitor link status, speed, and traffic statistics for each port.
• Registros: Review system logs for events, errors, and security alerts.
