Unmanaged switch TP‑LINK LS105P, 5x Fast Ethernet (10/100) ports, 4x PoE ports, 1 Gbit/s switching capacity, fanless, black

The 4-port 10/100 Mbps PoE switch provides 41 W total PoE budget and four 802.3af-compliant PoE ports that deliver up to 15.4 W each, enabling power and network connectivity for fixed devices such as IP cameras, wireless access points, and IP phones over a single Ethernet cable. The switch supports an extended PoE transmission mode that increases reach up to 250 m for deployments requiring longer cable runs. Its fanless design and metal enclosure offer quiet, durable operation suitable for desktop placement or wall mounting.

Advantages

The switch is plug-and-play with no configuration required, allowing quick installation. PoE Auto Recovery automatically reboots unresponsive PoE-powered devices to restore connectivity. Silent, fanless operation reduces noise and power consumption. The robust metal housing and flexible mounting options support use in different environments.

Key specifications

• Ports: Four 10/100 Mbps Ethernet ports with 802.3af PoE
• Total PoE budget: 41 W
• Per-port PoE output: Up to 15.4 W
• Extended PoE range: Up to 250 m in Extend Mode
• Operation: Plug and play, fanless design
• Mounting: Desktop or wall-mountable metal enclosure

How to use

Connect the switch to a power source and plug Ethernet cables from the switch ports to your PoE devices such as IP cameras or access points. If devices are located beyond standard Ethernet range, enable Extend Mode to increase PoE transmission distance up to 250 m. The switch requires no additional configuration; PoE ports will detect and power compatible devices automatically. If a PoE device becomes unresponsive, PoE Auto Recovery will attempt an automatic reboot to restore service.

Recommendations

For optimal performance, ensure the combined power draw of connected devices does not exceed the 41 W PoE budget. Use quality Ethernet cabling and follow recommended installation distances for non-extended mode to maintain network reliability.
