Installation Guide

10/100Mbps Desktop PoE/PoE+ Switch LS105LP/LS106LP/LS109P

LED Explanation

Power PoE Status

On: Providing PoE power
Flashing: Current-overload/Short-circuit
Off: Not providing PoE power
On: Power on
Off: Power of

PoE Status

On: Providing PoE power
Flashing: Current-overload/Short-circuit
Off: Not providing PoE power

PoE Max

For LS105LP/LS106LP: On: 34 W≤Total power supply < 41 W
Flashing: Total power supply ≥ 41 W Off: Total power supply < 34 W
For LS109P: On: 56 W≤Total power supply < 63 W Flashing: Total power supply ≥ 63 W Off: Total power supply < 56 W

Switches Explanation

Note: The numbers in brackets indicate the ports where the feature takes effect. For example, when Extend (Port 1-4) is toggled to On, the Extend mode will be enabled for ports 1-4.

Extend (For LS105LP/LS106LP/LS109P)

Off: The corresponding ports run at 10/100 Mbps and support PoE power supply up to 100 m away.
On: The corresponding ports run at 10 Mbps and support PoE power supply up to 250 m away.
Recovery (For LS105LP/LS106LP/LS109P)
Off: The PoE Auto Recovery function is disabled.
On: The switch will constantly detect the working status of a PoE powered device (PD). When the switchfinds that the PD works abnormally, the switch will reboot it.
Note: For simplicity, we will take LS106LP for example throughout this Guide.

Isolation (For LS109P)

Off: Ports can transmit data with each other.
On: The corresponding ports cannot transmit data with other downlink ports. They can transmit data only with the uplink port

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:
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.

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:
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).

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?

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.
