## Long description

The Netis System ST3105G (ST3120) Gigabit Ethernet switch is a compact 5-port unmanaged switch that delivers 10/100/1000 Mbps connectivity for small office and home networks. It provides five Auto-Negotiation RJ‑45 ports with Auto MDI/MDIX, enabling straightforward connection of PCs, printers, NAS devices and other Ethernet equipment without the need for crossover cables or dedicated uplink ports. The switch supports standard Ethernet protocols and offers plug-and-play operation together with a low-power design that simplifies upgrading an existing network to full gigabit speeds.
Advantages
The switch offers full-duplex gigabit performance on all ports, a MAC address table capable of storing up to 2000 entries for efficient frame forwarding, and compatibility with common IEEE networking standards (including IEEE 802.3, 802.3u, 802.3x and 802.1ab). Its Auto MDI/MDIX support removes cable-type constraints, while the wall-mountable enclosure and two-color options (black and white) allow flexible physical placement. No configuration is required, making it suitable for users who need a reliable, maintenance-free network extension.
Suitable for
Expanding wired ports for small offices and home networks
Connecting desktop PCs, network printers and IP cameras
Integrating a network-attached storage (NAS) device for faster local transfers
Upgrading legacy 100 Mbps switches to gigabit connectivity
Key specifications
Ports: 5 × RJ-45 Gigabit Ethernet (10/100/1000 Mbps) with Auto-Negotiation
Auto MDI/MDIX: supported on all ports
MAC address table size: 2000 entries
Duplex mode: full duplex and half duplex supported (auto-negotiation)
Standards supported: IEEE 802.3, IEEE 802.3u, IEEE 802.3x, IEEE 802.1ab
Power: DC-in jack (external power adapter required)
Form factor: compact, wall-mountable enclosure
Color options: black and white
How to use
Place the Netis ST3105G on a flat surface or mount it on a wall using the built-in mounting slots. Connect the external power adapter to the DC-in jack and plug it into a mains outlet. Use standard Ethernet cables to connect devices to any of the five RJ‑45 ports; the switch will automatically negotiate link speed and duplex mode. No configuration or management interface is required — once connected, devices will communicate at the highest mutually supported speed.
Usage recommendations
For best performance, use Cat5e or higher-rated Ethernet cables and ensure connected devices support gigabit Ethernet. Place the switch in a well-ventilated location away from heat sources and excessive dust. If stacking multiple switches in the same network, connect them via gigabit links and avoid creating network loops unless a spanning tree or equivalent loop prevention mechanism is present.
