TP-Link LS105LP/LS106LP/LS109P Desktop PoE+ Switch Installation Guide

Quick Guide

This guide covers the installation and operation of the TP-Link LS105LP, LS106LP, and LS109P Desktop PoE+ Switches. Key features include PoE+ support, Extend mode for long-distance transmission, and PoE Auto Recovery. Ensure your power source meets the switch requirements and that Ethernet cables are within the specified length limits (100m standard, 250m in Extend mode).

Connection

To set up the switch, connect the power adapter to the switch and a power outlet. Connect your router to the uplink port (or a standard port) and connect your PoE devices (such as IP cameras, access points, or IP phones) to the PoE ports. Note that PoE ports can also connect to non-PoE devices for data transmission only.

LED Explanation

The LEDs provide real-time status of the switch:

• Power: On indicates the switch is powered on.
• PoE Status: On indicates the port is providing PoE power; Flashing indicates a current overload or short-circuit.
• Link/Act: On indicates a link at 10/100 Mbps; Flashing indicates data transmission.
• PoE Max: Indicates the total power supply status. Flashing indicates the total power supply is at or above the threshold (41W for LS105LP/LS106LP, 63W for LS109P).

Switch Features

The switch includes specific modes to enhance functionality:

• Extend (LS105LP/LS106LP/LS109P): When enabled, ports run at 10 Mbps and support PoE power supply up to 250 meters away.
• Isolation (LS109P only): When enabled, ports cannot communicate with other downlink ports, only with the uplink port.
• Recovery (LS105LP/LS106LP/LS109P): When enabled, the switch constantly monitors the PoE powered device. If the device stops responding, the switch will automatically reboot it.

Troubleshooting

If you encounter issues, check the following:

• Power LED not lit: Ensure the power cord is connected properly and the power source is active.
• Link/Act LED not lit: Verify cable connections, ensure the connected device is powered on, and check that the cable length is within limits (100m or 250m if Extend mode is on).
• PoE ports not supplying power: If total power consumption exceeds the maximum, the switch prioritizes lower port numbers and may cut power to higher-numbered ports.

Specifications

• Standards: IEEE802.3i, IEEE802.3u, IEEE802.3x, IEEE802.3af, IEEE802.3at.
• PoE Budget: 41W (LS105LP/LS106LP) or 63W (LS109P).
• Operating Temperature: 0°C to 40°C (32°F to 104°F).
• Operating Humidity: 10% to 90% RH non-condensing.

Safety Information

Keep the device away from water, fire, humidity, or hot environments. Do not attempt to disassemble, repair, or modify the device. Place the device with its bottom surface downward. Use only the provided power adapter.
