The configuration steps differ for unmanaged and managed PoE switches.

非管理型 PoE 交換器設定

Take the TL-SG1005P as an example. Please refer to the following:

Step 1. Power on the POE switch.

Step 2. Locate the Extend Mode toggle and switch it to the ON position. The label on the device will indicate which ports support this mode. For TL-SG1005P, Extend Mode applies to ports 1–2.

Port Behavior:

• OFF – Ports operate at 10/100/1000 Mbps, with PoE support up to 100 m.
• ON – Ports operate at 10 Mbps, with PoE support up to 250 m.

Note: Actual transmission distance may vary depending on the PoE-powered device’s power consumption, cable quality, and cable type.

Step 3. Configuration complete. In Extend Mode, you can connect up to two powered devices (e.g., IP cameras) to the switch.

Configuration for Managed PoE Switches in Controller Mode

Step 1. Log in to the controller’s interface through Web broswer.

Step 2. Go to Site > Home > Quick Config, enable the Extend Mode and select the switch you want to configure.

Note: This feature is available only for controllers with version v5.15.22.40 and above.

For controllers below v5.15.22.40, Manually set the switch port speed to 10 Mbps. This also accomplishes the purpose of Extend Mode.

Go to Devices > Switch > Ports > enable Profile Overrides > Link Speed > enable Manual to configure the link speed of the switch port to 10Mbps/Auto.

Step 3. Click Apply to save the settings.

Configuration for Managed PoE Switches in Standalone Mode

Step 1. Log in to the switch web management page via its IP address.

Step 2. Go to L2 FEATURES > Switching > Port > Port Config and configure the desired ports.

Step 3. Click Apply and Save button to save the settings.

Conclusion

You have now learned how to configure Extend Mode on a PoE switch, whether it’s unmanaged or managed.
