3. Installation
3.1 Connexion d'alimentation
The switch supports dual redundant power inputs (PWR1 and PWR2) with a DC voltage range of 12V to 58V. Connect your external power supply to the terminal block on the side of the switch. Ensure correct polarity (P1+ and P1- for PWR1, P2+ and P2- for PWR2). The power supply is not included and must be purchased separately.

Connexion réseau 3.2
Connect your Ethernet devices (e.g., computers, cameras, routers) to any of the five 10/100Mbps RJ45 ports using standard Ethernet cables. The switch is unmanaged, meaning no configuration is required for basic network operation.
3.3 Montage sur rail DIN
The switch is designed for easy installation on a standard DIN-rail. Simply attach the integrated clip on the back of the switch to the DIN-rail until it clicks securely into place.

4. Mode d'emploi
4.1 indicateurs d'alimentation
- P1/P2 LEDs: These indicators illuminate when power is supplied to the corresponding PWR1 or PWR2 input. If both are lit, both power sources are active.
4.2 Ethernet Port Indicators
- Each Ethernet port has two LEDs: a yellow/orange light and a green light.
- Yellow/Orange & Green Light ON: Indicates a 100Mbps connection.
- Only Green Light ON: Indicates a 10Mbps connection.
- Lumières clignotantes: Indique une activité de données sur le port.

4.3 Unmanaged Operation
The keepLiNK Industrial Ethernet Switch is an unmanaged device. This means it operates automatically without requiring any software configuration. Simply connect your devices, and the switch will handle data forwarding.
5. Entretien
To ensure optimal performance and longevity of your industrial Ethernet switch, follow these maintenance guidelines:
- Nettoyage: Nettoyez régulièrement l'extérieur de l'interrupteur avec un chiffon doux et sec. N'utilisez pas de nettoyants liquides ni en aérosol.
- Conditions environnementales : Ensure the switch operates within its specified temperature range of -30°C to 75°C (-22°F to 167°F). While IP40 rated, avoid exposing the device to excessive moisture or direct water spray.
- Gestion des câbles: Keep network cables organized and free from kinks or excessive tension to prevent damage and ensure reliable connections.
- Vérification de l'alimentation électrique : Regularly inspect power connections for secure fit and any signs of wear or damage.
6. Dépannage
If you encounter issues with your keepLiNK Industrial Ethernet Switch, refer to the following common troubleshooting steps:
- Pas d'alimentation : Check if the power supply is correctly connected and providing the required DC12V-58V. Verify that the P1/P2 LEDs on the switch are illuminated.
- Aucun lien sur le port : Ensure the Ethernet cable is securely connected to both the switch port and the connected device. Check the cable for damage. Verify the connected device is powered on and functioning correctly.
- Vitesse de connexion lente : Observe the port LEDs. If only the green light is on, the connection is 10Mbps. If both yellow/orange and green lights are on, it's 100Mbps. Ensure your connected device supports 100Mbps and that the cable is not faulty.
- Connectivité intermittente : Check for loose cable connections. Ensure the operating environment is within the specified temperature range and free from excessive electromagnetic interference.
