Frequently Asked Questions (FAQ)

The Power LED should be lit when the power system is working normally. If the 

Power LED is not lit, please try the following:

A1:

 Make sure the AC power cord is connected to the switch with power source 

properly.

A2:

 Make sure the voltage of the power supply meets the requirements of the input 

voltage of the switch. 

A3:

 Make sure the power source is on. 

Q1. Why is the Power LED not lit? 

Please try the following:

A1:

 

Make sure that the cable connectors are firmly plugged into the switch and the 

device.

A2:

 Make sure the connected device is turned on and works normally. 

A3:

 The cable must be less than 100 meters long (328 feet).

Q2. Why is the Link/Act LED not lit while a device is connected to 

the corresponding port?

Q3. Why are PoE ports not supplying power for PoE devices?

When the total power consumption of connected PoE devices exceeds the 

maximum, the PoE port with a smaller port number has higher priority. The system 

will cut off power to the ports with larger port numbers to ensure supplying to other 

ports. 

Take TL-SG1005P as an example. If port 1, 2 and 4 are consuming 15.4 W 

respectively, and an additional PoE device with 19 W is inserted to port 3, the system 

will cut off the power of port 4 to compensate for the overload.
