TP-Link TL-SG108PE user manual

The lights on TP-Link switch, such as the TL-SG108PE, serve the purpose of status indicators. Here's what each of them represent:
1. Power Indicator: If this light is on, it indicates that the system is powered up and functioning as expected. If this light is off, the switch is not receiving any electrical power i.e., it is turned off.
2. Link/Act Indicator: Each port on the switch will have its own Link/Act LED. When this light is/stays on, it means a device is connected to that specific port and is in good working condition. When the light is off, no device is connected to that specific port. If the light is flashing, it means data is being transmitted or received through the port.
3. PoE Indicator: This light is on when the port is supplying power to a powered device. If it is off, the port has stopped supplying the power.
4. PoE Max: This indicator lights up when the total PoE power is reaching the maximum power. It flashes when the switch is in an overload state.
5. Mode Indicator: In Standard mode, when the indicator lights up, data transmission of all ports is normal. In Extend mode, the Link/Act LEDs of port 1-4 will be off, indicating the data rate is in 10Mbps in half-duplex operation, and the transmission distance can be as far as 250 meters.
Remember to ensure you are looking at the right light for the correct port when diagnosing issues. It is also recommended to consult the user manual specific to your model if you're unsure.
