TP-Link LS105LP User manual

Connection
Note: For simplicity, we will take LS106LP for example throughout this Guide.
Note:
1. PoE ports can also connect to non-PoE devices, but only transmit data.
2. LS105LP/ LS106LP can supply up to 15.4 W for each PoE port and 41 W for all PoE ports.
3. LS109P can supply up to 30 W for each PoE port and 63 W for all PoE ports.

Switches Explanation
Isolation (For LS109P)
O: 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.
Extend (For LS105LP/LS106LP/LS109P)
O: 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)
O: The PoE Auto Recovery function is disabled.
On: The switch will constantly detect the working status of a PoE powered device (PD). When the switch
nds that the PD works abnormally, the switch will reboot it.
Note: The numbers in brackets indicate the ports where the feature takes eect. For example, when Extend (Port 1-4) is toggled to On, the Extend mode will be enabled for ports 1-4.

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 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.
Q1. Why is the Power LED 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 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).
Q2. Why is the Link/Act LED not lit while a device is connected to
the corresponding port?
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 o 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 o the power of
port 4 to compensate for the overload.

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.
