2. Package Contents
Verify that your package contains the following items:
- TP-Link TL-SG108PE Switch
- Power Adapter
- Installation Guide
- Rubber Feet
3. Setup and Installation
Follow these steps to set up your TL-SG108PE switch:
- Prepare the Switch: Place the switch on a stable, flat surface or mount it to a wall using appropriate hardware (not included). Ensure adequate ventilation around the device. Attach the included rubber feet to the bottom of the switch if placing it on a desktop.
- Connect to Power: Connect the provided power adapter to the switch's power port and then plug the adapter into a standard electrical outlet. The Power LED on the switch will illuminate.
- Connect Network Devices:
- Connect your router or main network device to any of the 8 Gigabit RJ45 ports using an Ethernet cable.
- For PoE-powered devices (e.g., IP cameras, VoIP phones, wireless access points), connect them to ports 1-4. The switch will automatically detect and provide power to these devices.
- For non-PoE devices (e.g., computers, printers, network-attached storage), connect them to any of the 8 ports.
- Verify Connections: Check the LED indicators for each connected port. A solid green LED indicates a 1000 Mbps link, while a yellow LED indicates a 10/100 Mbps link. A flashing LED indicates activity. For PoE ports (1-4), a solid green PoE LED indicates power is being supplied, and a flashing green LED indicates a fault.

4. Operating the Switch
The TL-SG108PE is an Easy Smart Managed Switch, offering both plug-and-play functionality and advanced management options.
4.1 Basic Operation (Plug and Play)
Once connected as described in the Setup section, the switch will automatically detect and configure connected devices. No further action is required for basic network connectivity.
4.2 Advanced Management
For advanced features such as VLAN, QoS, and IGMP Snooping, access the switch's web-based management interface or use the smart configuration utility.
Figure 3: Accessing the management utility for advanced configuration.
Accessing the Management Interface:
- Ensure your computer is connected to the switch.
- Refer to the Installation Guide for the default IP address and login credentials.
- Open a web browser and enter the switch's IP address.
- Log in using the provided credentials to access the configuration options.
4.3 Power over Ethernet (PoE) Functionality
The TL-SG108PE provides power to compatible devices through ports 1-4. The total power budget is 64W, with up to 30W available per port. The switch features:
- PoE Auto Recovery: If a PoE-powered device becomes unresponsive, the switch can automatically detect this and reboot the device, restoring functionality.
- Intelligent Power Management: Prioritizes power delivery to critical devices and manages the total power budget to prevent overload.
- PD Detection: Automatically detects the required PoE power for your device and protects non-PoE equipment from damage.

5. Maintenance
To ensure optimal performance and longevity of your TL-SG108PE switch, consider the following maintenance guidelines:
- Environment: Operate the switch within its specified temperature and humidity ranges. Avoid placing it in direct sunlight, near heat sources, or in areas with excessive dust or moisture.
- Ventilation: Ensure that the ventilation holes on the sides of the switch are not blocked to allow for proper airflow and heat dissipation.
- Cleaning: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners.
- Firmware Updates: Check the TP-Link official website periodically for firmware updates. Keeping the firmware updated can improve performance, add new features, and address security vulnerabilities.
- Cable Management: Ensure network cables are neatly organized and not excessively bent or strained to prevent signal degradation or damage.
6. Troubleshooting
If you encounter issues with your TL-SG108PE switch, refer to the following common troubleshooting steps:
- No Power: Ensure the power adapter is securely connected to both the switch and a working electrical outlet. Check the Power LED on the switch.
- No Link/Connectivity: Verify that Ethernet cables are properly connected to both the switch and the network device. Check the link/activity LEDs on the switch ports. Try a different Ethernet cable or port.
- PoE Device Not Powering On: Ensure the PoE device is connected to one of ports 1-4. Check the PoE LED for the respective port. Confirm the PoE device is 802.3af/at compliant and that the total power budget (64W) is not exceeded.
- Slow Network Speed: Ensure all connected devices and cables support Gigabit Ethernet for optimal performance. Check for excessive network traffic or potential cable issues.
- Cannot Access Management Interface: Verify your computer's IP address is in the same subnet as the switch. Ensure there are no IP address conflicts. Try resetting the switch to factory defaults (refer to the Installation Guide for instructions on using the Reset button).
- Intermittent Connectivity: Check for loose cable connections. Ensure the switch is not overheating. Consider updating the switch firmware.
