Switches Explanation

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

Extend (for TL-SF1008LP/TL-SF1008P/TL-SF1009P/TL-SL1311MP)

Off: Ports run at 10/100 Mbps and support PoE power supply up to 100 m away.On: Ports run at 10 Mbps and support PoE power supply up to 250 m away.

Priority (only for TL-SF1008LP/TL-SF1008P/TL-SF1009P)Off: All the ports transmit data with the same priority.On: The specific ports transmit data with a higher priority than other ports.

Recovery (only for TL-SF1008P/TL-SL1311MP)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 switch finds that the PD works abnormally, the switch will reboot it.

Isolation (only for TL-SF1009P/TL-SL1311MP)Off: Ports can transmit data with each other.On: Specific ports cannot transmit data with other downlink ports. They can transmit data only with the uplink ports.

Note: For simplicity, we will take TL-SF1008P for example throughout the Guide.



  1. PoE ports can also connect to non-PoE devices, but only transmit data.
  2. TL-SL1311MP has three uplink ports, which typically connect to uplink devices like routers. Uplink 1 is an SFP slot and works with a 1000 Mbps SFP module. Uplink 2 and uplink 3 are RJ45 ports.

Frequently Asked Questions (FAQ)

Q1. The Power LED is not lit.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 has connected to the switch with the 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. The Link/Act LED is not lit when 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 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).

Q3. Why are 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 a higher priority. The system will cut off power to the ports with larger port numbers to ensure supply to other ports.

Take TL-SF1008P as an example. If ports 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.

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.

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