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 check as follows:
A1: 
Make sure the AC power cord is connected 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. The Power LED is not lit.
It is recommended that you check the following items:
A1:
 Make sure that the cable connectors are rmly plugged into the switch and the device.
A2: 
Make sure the connected device is turned on and working well. 
A3:
 The cable must be less than 100 meters long (328 feet). If Extend Mode is enabled, it 
should be less than 250 meters (820 feet).
Q2. Why is the Link/Act LED not lit while a device is connected to 
the corresponding port?

Q3. Why is PoE/PoE+ Port 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 a higher priority. The system will cut o power to 
the ports with larger port numbers to ensure supplying to other ports.
Take TL-SG1008P as an example. If port 1, 2 and 4 are consuming 15.4 W respectively, and 
an additional PoE device with 20 W is connected to port 3, the system will cut o the power 
of port 4 to compensate for the overload.

General Specications
A1: 
Before upgrading a connected PoE powered device (PD), disable PoE Auto Recovery to 
avoid the PD’s damage.
A2:
 When a PD does not send data packets to the switch for a long period in certain 
scenarios (e.g. an IPC in sleep mode), disable PoE Auto Recovery to avoid the PD 
repeatedly rebooting. 
Q4. What should I notice before using the PoE Auto Recovery 
feature?
