Network switch Cudy GS105U — Unmanaged 5-port Gigabit Ethernet (10/100/1000), white, 5 V

Cudy GS105U is an unmanaged 5‑port Gigabit Ethernet (10/100/1000) desktop switch designed for simple wired network expansion. The compact white unit offers five RJ‑45 ports, a 2048‑entry MAC address table and a 10 Gbit/s switching capacity. Compliant with IEEE 802.3ab/i/u/x standards, it is powered via 5 V DC with a USB‑C power supply and can be placed on a desk or mounted on a wall for convenient use in home or small office environments.

Advantages

The Cudy GS105U provides straightforward plug‑and‑play connectivity without configuration, enabling immediate network extension. Its Gigabit ports deliver full‑duplex speeds for connected devices, while the 2048‑entry MAC table helps manage local traffic efficiently. The compact, white housing is unobtrusive on a desk and includes wall‑mounting options. USB‑C power input allows flexible powering solutions using common 5 V adapters or USB power sources.

How to use

Place the Cudy GS105U on a flat surface or mount it to a wall using the integrated mounting slots. Connect the included USB‑C power cable to a compatible 5 V adapter or USB power source and plug it into the switch. Attach Ethernet cables from your router, modem or upstream switch to one port and connect other wired devices to the remaining RJ‑45 ports. The device operates without configuration; link/activity LEDs indicate port status and data transfer.

Recommendations

For optimal performance, use quality Cat5e or Cat6 cables and ensure connected devices support Gigabit speeds. Place the switch in a well‑ventilated area away from heat sources and moisture. If using a USB power bank or third‑party adapter, verify it supplies stable 5 V output at sufficient current for continuous operation.
