3.1. Energy Efficiency (GREENnet Technology)
TRENDnet's GREENnet technology is an embedded energy-saving feature that reduces power consumption without affecting performance. This technology helps lower electricity bills and contributes to environmental conservation.
4. Operating the Switch
Once powered on and connected, the TRENDnet TEG-S25D switch operates automatically. It is an unmanaged switch, meaning it requires no configuration. Data transfer begins immediately upon connecting devices.
4.1. LED Indicators
The front panel of the switch features LED indicators that provide real-time status information for each port and the device itself. These LEDs are crucial for monitoring network activity and troubleshooting.
- PWR (Power) LED: Indicates the power status of the switch.
- LINK/ACT (Link/Activity) LEDs: For each port, a solid light indicates a successful network link, and a blinking light indicates data activity.
- 10/100/1000 (Speed) LEDs: For each port, indicates the connection speed (e.g., green for Gigabit, amber for Fast Ethernet).

6. Maintenance
To ensure optimal performance and longevity of your TRENDnet TEG-S25D switch, consider the following maintenance tips:
- Ventilation: Ensure the switch is placed in a well-ventilated area. Do not block the ventilation holes on the sides of the device.
- Cleaning: Regularly clean the exterior of the switch with a soft, dry cloth. Avoid using liquid or aerosol cleaners.
- Cable Management: Keep network cables organized to prevent accidental disconnections and improve airflow.
- Power Protection: Connect the switch to a surge protector or an Uninterruptible Power Supply (UPS) to protect against power fluctuations.
7. Troubleshooting
If you encounter issues with your TRENDnet TEG-S25D switch, try the following basic troubleshooting steps:
- No Power: Check if the power cord is securely connected to both the switch and the electrical outlet. Verify the power outlet is functional.
- No Link Light: Ensure the Ethernet cable is securely connected to both the switch port and the network device. Try a different cable or port. Verify the connected device is powered on and functioning correctly.
- Slow Connection: Check the speed LED for the connected port to confirm it's operating at the expected speed (e.g., 1000Mbps for Gigabit). Ensure your Ethernet cables are rated for Gigabit speeds (Cat5e or higher).
- Network Congestion: If multiple devices are experiencing slow speeds, ensure your internet service provider (ISP) connection is adequate for your usage. Consider upgrading network infrastructure if consistently experiencing high traffic.
