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 firmly 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. The Link/Act LED is not lit when a device is connected to the
corresponding port.
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 off power to
the ports with larger port numbers to ensure supplying to other ports.
Take TL-SF1008P as an example. If port 1, 2 and 4 are consuming 15.4 W respectively, and
an additional PoE device with 20 W is inserted to port 3, the system will cut off the power of
port 4 to compensate for the overload.
Q3. Why are PoE ports not supplying power for PoE devices?

PoE Disclaimer
The speed of the ports in extend mode will downgrade to 10 Mbps. The actual transmission
distance may vary due to power consumption of PoE-powered devices or the cable quality
and type.
PoE budget calculations are based on laboratory testing. Actual PoE power budget is not
guaranteed and will vary as a result of client limitations and environmental factors.

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