3. Pokyny k nastavení

Follow these steps to properly connect your DIGITUS Cat 8.1 LAN Cable:

1. Identifikace portů: Locate the Ethernet ports on your network devices (e.g., router, switch, computer, server, gaming console, Smart TV). These are typically RJ45 ports.
2. Připojení prvního konce: Gently insert one end of the DIGITUS Cat 8.1 LAN Cable into the Ethernet port of your first device until you hear a click, indicating it is securely latched.
3. Připojení druhého konce: Insert the other end of the cable into the Ethernet port of your second device. Ensure it also clicks into place.
4. Ověřit připojení: Most network devices have indicator lights next to the Ethernet port. A solid or blinking light typically indicates a successful connection and data activity.
5. Vedení kabelů: Route the cable carefully to avoid sharp bends, kinks, or excessive tension, which can damage the cable and degrade performance.

The cable's RJ45 connectors are designed for secure and reliable connections, featuring a snap lever protection to prevent accidental disconnections.

4. Obsluha kabelu

Once connected, the DIGITUS Cat 8.1 LAN Cable operates passively to facilitate data transfer between your network devices. No specific user interaction is required for its operation beyond proper connection.

4.1. High-Speed Networking

This cable is engineered to support extremely high data transfer rates, making it suitable for:

• Data centers and server rooms requiring 25/40 Gigabit Ethernet.
• High-performance computing and cloud environments.
• Gaming setups where low latency and high bandwidth are critical.
• Streaming 4K/8K UHD content without buffering.

4.2. Power over Ethernet (PoE++)

If your connected devices and network equipment support PoE++ (IEEE 802.3bt), this cable can transmit both data and power up to 100W. This eliminates the need for separate power cables for compatible devices such as IP cameras, VoIP phones, and wireless access points.

5. Údržba

The DIGITUS Cat 8.1 LAN Cable is designed for durability and requires minimal maintenance. Adhering to the following guidelines will help ensure its long-term performance:

• Vyhněte se fyzickému stresu: Do not bend the cable sharply, crimp it, or place heavy objects on it. Excessive bending can damage the internal conductors and shielding, leading to performance degradation.
• Správná manipulace: When disconnecting, always press the release tab on the RJ45 connector before pulling. Never pull directly on the cable itself, as this can damage the connector or the cable's internal wiring.
• Čistota: Keep the connectors free from dust and debris. If necessary, gently clean the metal contacts with a dry, lint-free cloth or compressed air.
• Podmínky prostředí: Store and operate the cable in a dry environment, away from extreme temperatures and direct sunlight. The LSZH jacket provides protection, but proper environmental conditions are still recommended.
• Inspekce: Periodically inspect the cable and connectors for any signs of wear, damage, or corrosion. Replace the cable if any damage is observed.

6. Řešení problémů

If you encounter issues with your network connection, consider the following troubleshooting steps:

• Žádné síťové připojení:
  • Ensure both ends of the cable are securely plugged into their respective ports. Listen for the "click" sound.
  • Check the indicator lights on your network devices. If they are off, try a different port or device.
  • Test the cable with another known working device or replace it with a different Ethernet cable to rule out a faulty cable.
  • Restart your router/modem and the connected device.
• Pomalá rychlost sítě:
  • Verify that all network components (router, switch, network adapter) support the desired speed (e.g., 10Gbps or 40Gbps). A Cat 8.1 cable will only perform at the speed of the slowest component in the chain.
  • Ensure the cable is not bent, kinked, or damaged. Physical damage can significantly reduce performance.
  • Check for sources of electromagnetic interference (EMI) near the cable, although the S/FTP shielding and PCB in the connector are designed to mitigate this.
  • Update network adapter drivers on your computer.
• Přerušované připojení:
  • Ensure connectors are clean and free of debris.
  • Zkontrolujte uvolněné spoje.
  • If possible, test with a different cable to determine if the issue is with the cable or other network hardware.

For persistent issues, refer to the documentation for your network devices or contact technical support.
