2.2. Device Connection

Connect the switch to your network and power supply as follows:

• Connect the switch to the power supply using the provided power cord.
• The uplink RJ45 ports (17-18) on the switch can be connected to devices such as NVRs or routers.
• The uplink SFP interfaces (19-20) can be combined with fiber modules to connect fiber lines, enabling long-distance transmission.
• The 16 PoE power supply ports (1-16) can be connected to PoE-powered devices such as IP cameras, wireless access points (APs), and IP phones.

3. Operating Modes

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

• Standard Mode: All ports communicate freely, functioning as a typical unmanaged PoE switch.
• Priority Mode: Ports 1-8 are prioritized to reduce packet loss and congestion, ideal for critical devices.
• Extend Mode: 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.
• VLAN Mode: 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.

4. Maintenance

To ensure optimal performance and longevity of your Tenda TEG1120P-16-250W switch, consider the following maintenance guidelines:

• Environment: Operate the switch within its specified temperature range (up to 40 Degrees Celsius) and in a well-ventilated area to prevent overheating.
• Cleaning: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid or aerosol cleaners.
• Cable Management: Ensure all network cables are properly organized and secured to prevent accidental disconnections or damage.
• Power Supply: Use only the provided power adapter. Avoid overloading the power circuit.
• Firmware Updates: Periodically check the manufacturer's website for any available firmware updates to enhance performance and security.

5. Troubleshooting

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

• No Power: Ensure the power cord is securely connected to both the switch and a working power outlet. Check the power indicator LED on the switch.
• No Network Connectivity: 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.
• PoE Device Not Powering On: 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.
• Slow Network Speed: 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.
• Device Not Recognized: Restart both the switch and the connected device.

If problems persist after attempting these steps, please contact Tenda customer support for further assistance.
