4. Instrucciones de configuración
4.1 Instalación física
- Elija una ubicación: Place the switch on a stable, flat surface (desktop), mount it on a wall, or install it in a 19-inch rack using the provided kit. Ensure adequate ventilation around the switch to prevent overheating.
- Conexión de energía: Connect the provided power cord to the AC IN port on the rear panel of the switch and then to a standard AC power outlet (100-240V).
- Conexiones de red:
- Connect your Power over Ethernet (PoE) compatible devices (e.g., IP cameras, wireless access points, IP phones) to any of the 16 PoE+ ports (ports 1-16) using standard Ethernet cables.
- Connect your network backbone (e.g., router, NVR, main switch) to one of the 2 Gigabit uplink ports (ports 17-18) using a standard Ethernet cable.

5. Instrucciones de funcionamiento
5.1 Encendido
After connecting the power cord, the switch will automatically power on. The Power LED indicator on the front panel will illuminate, indicating that the device is receiving power.
5.2 Indicadores LED
| Indicador | Estado | Descripción |
|---|---|---|
| LED de encendido | On | El interruptor está encendido. |
| Link/Act LED (Per Port) | On | Un dispositivo está conectado al puerto. |
| Brillante | Se están transmitiendo o recibiendo datos a través del puerto. | |
| PoE LED (Per PoE Port) | On | Se suministra alimentación PoE al dispositivo conectado. |
| Brillante | PoE power fault or overload detected. |
5.3 Modo VLAN
The switch features a physical VLAN switch on the front panel. When enabled, this mode isolates the PoE ports (ports 1-16) from each other, preventing direct communication between them. All PoE ports can still communicate with the uplink ports (ports 17-18). This feature enhances network security and can improve bandwidth utilization for specific applications like surveillance systems.
- Default (VLAN Disabled): Todos los puertos pueden comunicarse entre sí.
- Extend (VLAN Enabled): PoE ports are isolated from each other but can communicate with uplink ports.

6. Mantenimiento
- Limpieza: Utilice un paño suave y seco para limpiar el exterior del interruptor. No utilice limpiadores líquidos ni en aerosol.
- Ventilación: Ensure that the ventilation openings are not blocked. Maintain adequate space around the switch for proper airflow.
- Condiciones ambientales: Opere el interruptor dentro de los rangos de temperatura y humedad especificados (consulte la sección Especificaciones).
- Actualizaciones de firmware: Como es un conmutador no administrado, generalmente no se requieren actualizaciones de firmware.
7. Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| Sin poder | Power cord not connected or power outlet is faulty. | Ensure the power cord is securely connected to both the switch and a working power outlet. Check the power outlet with another device. |
| Sin enlace/actividad en un puerto | Cable Ethernet defectuoso, tipo de cable incorrecto o el dispositivo conectado está apagado o defectuoso. | Verify the Ethernet cable is correctly connected and not damaged. Ensure the connected device is powered on and functioning. Try a different port or cable. |
| No PoE Power to Device | Device is not PoE compatible, total power budget exceeded, or faulty cable. | Ensure the connected device supports IEEE 802.3af/at PoE standards. Check the total power consumption of all connected PoE devices to ensure it does not exceed 250W. Verify the Ethernet cable. If the PoE LED is flashing, there might be a power fault or overload. |
| Network Performance Issues | High network traffic, faulty cables, or incorrect VLAN setting. | Check for excessive network activity. Ensure all cables are in good condition. If VLAN mode is enabled, ensure it is configured as desired for your network setup. |
