Frequently Asked Questions (FAQ)
Specifications
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-SG108PE as an example. Port 1, 2 and 4 are consuming 15.4 W respectively.
If an additional PoE device with 18 W is inserted to port 3, the system will cut off the
power of port 4 to compensate for the overload.
Q3. Why is PoE/PoE+ Port not supplying power for PoE devices?
Q1. Why is the Power LED not lit?
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 power adapter 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.
A4:
On the LED On/Off configuration page, check whether the LED status is on. By
default, the LED status is on.
Q2. Why is the Link/Act LED not lit while a device is connected to
the corresponding port?
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). If Extend Mode is
enabled, it should be less than 250 meters (820 feet).
A4:
On the LED On/Off configuration page, check whether the LED status is on. By
default, the LED status is on.
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.
