tp-link TL-SF1008LP Unmanaged Desktop PoE/PoE+ Switch Installation Guide

LED Explanation

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)

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.

Recovery (only for TL-SF1008P)

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.

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.

Isolation (only for TL-SF1009P)

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

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

Connection

Note: PoE ports can also connect to non-PoE devices, but only transmit data.

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 know 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 is in a certain mode (e.g. an IPC in sleep mode) in which it does not send data packets to the switch for a long period, disable PoE Auto Recovery to avoid the PD repeatedly rebooting.

PoE Disclaimer

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