3. Tryby pracy

The TEG1120P-16-250W switch features a mode switch that allows you to select from four operating modes to suit different network scenarios:

Figure 6: Mode Switch on the Device

• Tryb standardowy: All ports communicate freely, functioning as a typical unmanaged PoE switch.
• Tryb priorytetowy: Ports 1-8 are prioritized to reduce packet loss and congestion, ideal for critical devices.
• Tryb rozszerzania: Ports 9-16 support extended transmission up to 250 meters, with full inter-port communication. Speed for these ports will be downgraded to 10 Mbps for distances between 100m-200m. This mode is ideal for surveillance systems.
• Tryb VLAN: PoE+ ports 1-16 are isolated from each other but maintain communication with the uplink ports (17-20, SFP1, SFP2). This protects against broadcast storms and DHCP spoofing.

• Środowisko: Operate the switch within its specified temperature range (up to 40 Degrees Celsius) and in a well-ventilated area to prevent overheating.
• Czyszczenie: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners.
• Zarządzanie kablami: Ensure all network cables are properly organized and secured to prevent accidental disconnections or damage.
• Zasilanie: Use only the provided power adapter. Avoid overloading the power circuit.
• Aktualizacje oprogramowania układowego: Okresowo sprawdzaj producenta website for any available firmware updates to enhance performance and security.

5. Rozwiązywanie Problemów

If you encounter issues with your Tenda TEG1120P-16-250W switch, try the following troubleshooting steps:

• Brak zasilania: Ensure the power cord is securely connected to both the switch and a working power outlet. Check the power indicator LED on the switch.
• Brak połączenia sieciowego: Verify that Ethernet cables are properly connected to both the switch and the connected devices. Check the link/activity LEDs for each port. Try using different cables or ports.
• Urządzenie PoE nie włącza się: Confirm that the connected device is PoE compatible (IEEE 802.3af/at). Check the PoE status LED for the port. Ensure the total PoE power budget (230W) is not exceeded. If intelligent power management has activated, lower priority ports may be temporarily unpowered.
• Niska prędkość sieci: Check for excessive network traffic or potential cable issues. In Extend Mode, ports 9-16 operate at 10 Mbps; ensure this is suitable for your application.
• Network Loops/Broadcast Storms: If experiencing network instability, ensure VLAN mode is enabled if required to isolate ports and prevent broadcast storms.
• Urządzenie nierozpoznane: Restart both the switch and the connected device.
