Frequently Asked Questions - TL-SL1311P TP-LINK

Why is the Power LED not lit?

Check that the AC power cord is securely connected to the switch and the power source. Ensure the voltage meets the switch's input requirements and the power source is turned on.

Why is the Link/Act LED not lit when a device is connected?

Ensure the cable connectors are firmly plugged into both the switch and the device. Verify the connected device is powered on and working. The cable length must not exceed 100 m (328 ft), or 250 m (820 ft) if Extend Mode is enabled.

Why are the PoE ports not supplying power to my PoE device?

If the total power consumption of connected PoE devices exceeds the PoE budget (65 W), the switch prioritizes lower-numbered ports and cuts power to higher-numbered ports. For example, if ports 1, 2, and 4 use 15.4 W each and a 20 W device is added to port 3, power to port 4 is cut.

What should I know before using the PoE Auto Recovery feature?

Disable PoE Auto Recovery before upgrading a connected PoE powered device (PD) to avoid damage. Also disable it if a PD does not send data for long periods (e.g., an IPC in sleep mode) to prevent repeated reboots.

What is the maximum cable length for normal and Extend modes?

In normal mode, the maximum cable length is 100 m (328 ft). When Extend Mode is enabled (via the switch's physical toggle for ports 1-4), ports operate at 10 Mbps and support PoE power up to 250 m (820 ft).

Can non-PoE devices be connected to PoE ports?

Yes, PoE ports can also connect to non-PoE devices, but they will only transmit data and not supply power.

How do I reset the switch to factory defaults?

The TL-SL1311P does not have a reset button. To reset, disconnect the power supply and reconnect it after a few seconds. This will clear dynamic settings but not change physical switch toggles.

What SFP modules are supported?

The SFP slot supports 1000 Mbps SFP modules (e.g., 1000BASE-SX, LX, LX10, BX10). Use only compatible modules from reputable manufacturers.

Is the switch wall-mountable?

Yes, the switch is wall-mountable. The distance between mounting holes is 150 mm. Use appropriate screws (not included) to secure it.

What safety precautions should I follow?

Keep the device away from water, fire, humidity, and hot environments. Do not disassemble, repair, or modify the device. Use only the provided power adapter. The socket-outlet should be easily accessible to disconnect power.

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 1-4.

Extend (for TL-SF1008LP/TL-SF1008P/TL-SF1009P/TL-SL1311P/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 (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 (For TL-SF1008P/TL-SF1009P/TL-SL1311P/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 (For TL-SF1009P/TL-SL1311P/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:

1. PoE ports can also connect to non-PoE devices, but only transmit data.
2. TL-SL1311MP/TL-SL1311P 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 is connected 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. 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 supplying to other ports.

Take TL-SF1008P as an example. If port 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.
