Frequently Asked Questions - LS105LP TP-LINK

How many PoE ports does the TP-Link LS105LP have?

The LS105LP has 4 PoE ports (ports 1-4) and 1 uplink port (port 5). All ports are 10/100Mbps.

What is the PoE power budget of the LS105LP?

Each PoE port can deliver up to 15.4W (802.3af). The total PoE power budget is 61.6W when all four ports are used.

Does the LS105LP support 802.3at (PoE+)?

No, the LS105LP only supports IEEE 802.3af (PoE). For 802.3at support, consider other models like LS108GP.

How do I enable Extend Mode on the LS105LP?

Extend Mode is typically enabled via a physical switch on the device or through the web interface. It extends the data and power transmission distance to 250 m at 10 Mbps.

What is the maximum cable distance for normal operation?

Standard operation supports 100 m (328 ft) over Cat5e or better cable. With Extend Mode enabled, distance can reach up to 250 m.

Does the LS105LP require configuration?

No, the LS105LP is a plug-and-play switch. It automatically detects and powers PoE devices without any manual configuration.

Can I connect a non-PoE device to a PoE port?

Yes, the switch automatically detects if the connected device is PoE-compliant. Non-PoE devices will receive only data, not power, and are safe to connect.

What is the switching capacity of the LS105LP?

The switching capacity is 1.0 Gbps, which is sufficient for 5 ports of 10/100Mbps full-duplex.

How do I reset the LS105LP to factory defaults?

If the switch has a reset button, press and hold it for about 10 seconds while the device is powered on. Release when the LEDs flash.

Does the LS105LP support VLAN or Isolation Mode?

No, the LS105LP does not support VLAN or Isolation Mode. These features are available on models like LS109P and LS1210GP.

USER MANUAL LS105LP TP-LINK

LS106LP/LS108GP LS109P/LS1210GP

Overview

The TP-Link LiteWave Series PoE Switches require no configuration and provide PoE (Power over Ethernet) ports. They can automatically detect and supply power with all IEEE 802.3af/at compliant Powered Devices (PDs). In this situation, the electrical power is transmitted along with data in one single cable allowing you to expand your network to where there are no power lines or outlets, where you wish to fix devices such as APs, IP Cameras or IP Phones, etc.

Highlights

• With multiple PoE ports, transfer data and power on one single cable
• Working with IEEE 802.3af /at compliant PDs, expand your network*
• 802.1p/DSCP QoS enable smooth latency-sensitive traffic
• Up to 250 m data and power transmission under Extend Mode** specially designed for surveillance system
• Isolation Mode (for LS109P&LS1210GP only) allows one-click client traffic separation for higher security and performance
• PoE Auto Recovery guarantees stable operation of PoE devices by automatically rebooting the dropped or unresponsive PD devices
• Plug and play, no configuration and installation required

Note:
* LS105LP and LS106LP only support IEEE 802.3af, and provide PoE Power up to 15.4W for each PoE port; other switches support IEEE 802.3af/at, and provide PoE Power up to 30W for each PoE port.
** The speed of the ports which are under extend mode will be downgraded to 10Mbps. Actual transmission distance may vary from the quality of the cables.
*** 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.
