Five-port Gigabit switch

The TP-Link TL-SG105 is an unmanaged desktop switch with five RJ45 ports operating at 10/100/1000Mbps. It uses store-and-forward switching and supports 9K jumbo frames for efficient data transfer. A sturdy metal enclosure provides fanless, silent operation and allows desktop or wall mounting.

Home and small-office expansion

This switch suits users who need extra wired connections for devices such as laptops, consoles or printers without any configuration. It is not for networks requiring PoE, uplink ports, VLANs or Layer 3 routing features. Buyers needing managed traffic control or redundant power should look elsewhere.

Capacity and headroom

Five Gigabit ports deliver full-duplex throughput up to 2000Mbps per port with IEEE 802.3x flow control. QoS prioritises latency-sensitive voice and video traffic while 84 percentage power saving reduces consumption based on link status and cable length. The switch runs out of ports at five devices and offers no fibre uplinks or stacking.

Questions about this item

What cables and devices do I need to connect to the 5 RJ45 ports running at 10/100/1000 Mbps?

You need standard Ethernet cables (Cat5e or better) and devices with RJ45 network ports such as a router, PC, NAS, printer or game console. The switch auto-negotiates speed and MDI/MDIX so no crossover cables are required.

Will my older 10/100 Mbps gear slow down the gigabit ports on this switch?

No. Each port negotiates independently at 10, 100 or 1000 Mbps, so legacy 10/100 devices run at their rated speed while gigabit devices still operate at 1000 Mbps on the other ports.

How can I verify the switch is passing traffic correctly after I plug everything in?

Check the per-port LEDs built into each RJ45 jack — a steady or blinking link/activity light shows an active connection and data flow, while the system power LED confirms the unit is receiving 100–240 V AC power.
