FAQs
Can the PoE ports connect to non-PoE devices?
Yes, the PoE ports can also connect to non-PoE devices, but they will only
transmit data and not provide power.
What is the maximum power supply for each PoE port?
For LS105LP/LS106LP, each PoE port can supply up to 15.4 W. For LS109P, each
PoE port can supply up to 30 W.
What is the total PoE budget for the switch?
For LS105LP/LS106LP, the total PoE budget is 41 W. For LS109P, the total PoE
budget is 63 W.
What is the purpose of the Recovery mode?
The Recovery mode constantly detects the working status of a PoE powered
device (PD). If the switch detects that the PD works abnormally, it will
automatically reboot it.

Frequently Asked Questions (FAQ)
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:
- Make sure the AC power cord is connected to the switch with power source properly.
- Make sure the voltage of the power supply meets the requirements of the input voltage of the switch.
- Make sure the power source is on.
Q2. Why is the Link/Act LED not lit while a device is connected to the corresponding port?
It is recommended that you check the following items:
- Make sure that the cable connectors are firmly plugged into the switch and the device.
- Make sure the connected device is turned on and works normally.
- 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).
Q3. Why are the 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 LS106LP as an example. If port 1, 2 and 4 are consuming 10 W
respectively, and an additional PoE device with 15 W is connected to port 3,
the system will cut off the power of port 4 to compensate for the overload.
Q4. What should I notice before using the PoE Auto Recovery feature?
- Before upgrading a connected PoE powered device (PD), disable PoE Auto Recovery to avoid the PD’s damage.
- 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.
