Unmanaged switch TP-Link TL-SG105S 5-poorts 10/100/1000Mbps

The TP-Link TL-SG105S is an unmanaged 5-port Gigabit Ethernet desktop switch that provides a simple way to add 10/100/1000 Mbps connectivity to a home or small office network. With five RJ‑45 Gigabit ports and a switching capacity of 10 Gbit/s, the TL-SG105S supports full-duplex operation and a 2,000‑entry MAC address table. The compact, fanless design is suitable for quiet environments and can be wall-mounted if required.

Advantages

The switch delivers gigabit speeds to multiple devices without configuration, offering plug-and-play installation and auto MDI/MDIX on all ports. Energy-efficient technology adjusts power based on link status and cable length to reduce consumption. QoS (802.1p and DSCP) and IGMP Snooping help optimize latency-sensitive traffic and multicast streams. Its unmanaged design and compliance with IEEE networking standards make it compatible with typical home and office equipment.

Suitable for

• Expanding wired connections for home networks
• Small office or workgroup desktop connections
• Connecting NAS, printers, or IP cameras requiring Gigabit
• Low-noise environments thanks to fanless operation

How to use

Place the TL-SG105S on a stable surface or mount it on a wall using compatible screws. Connect each device to the RJ‑45 ports with standard Ethernet cables; the switch supports auto-negotiation to select 10/100/1000 Mbps speeds and auto MDI/MDIX to eliminate crossover cables. Power on the unit and observe the link/activity LEDs to verify connections. No further configuration is required for basic operation.

Recommendations

For optimal energy savings, use high-quality Ethernet cables and avoid unnecessarily long cable runs. Place the switch in a well-ventilated, dust-free location and connect devices that require stable, low-latency links (such as NAS, IP cameras, or VoIP equipment) to the Gigabit ports.
