LED Explanation
Understanding the status indicators on your switch.
Power LED
On: Power on Off: Power off
Link/Act LED (For TL-SG105/TL-SG105S/TL-SG108/TL-SG108S)
- Link/Act (Green):
- On: Running at 10/100/1000 Mbps
- Off: No device is linked to the corresponding port
- Flashing: Transmitting/receiving data
Link/Act LED (For TL-SG116)
- 1000M (Green):
- On: Running at 1000 Mbps
- Flashing: Transmitting/receiving data
- 10/100M (Yellow):
- On: Running at 10/100 Mbps
- Flashing: Transmitting/receiving data
?Note: For simplicity, this guide uses the TL-SG108 as an example throughout.
Connection
?Diagram Description: Illustrates the network connection setup. An 'Internet' source connects to a 'Router' via its 'WAN Port'. The 'Router's 'LAN Port' connects to the TP-Link 'TL-SG108' switch. The switch has a 'Power' input and 'Ethernet Ports (1-8)'. A 'Power Adapter' connects to the switch. Two 'PC' devices are shown connected to the switch's Ethernet ports.
