Gigabit Ethernet Switch Zyxel GS-105B v5 — 5-Port Unmanaged Desktop Switch

Zyxel GS-105B v5 is a compact 5-port Gigabit Ethernet unmanaged desktop switch designed to extend wired network capacity with minimal setup. The device provides five Auto-MDI/MDIX RJ-45 ports supporting 10/100/1000 Mbps data rates, enabling direct connections for PCs, printers, NAS units and other Ethernet-enabled devices. Its plug-and-play operation, fanless design and low power consumption make it suitable for quiet environments where basic, reliable switching is required.

Advantages

The Zyxel GS-105B v5 offers straightforward installation with no configuration required, making it easy to add wired ports to existing networks. Gigabit-capable ports deliver higher transfer speeds compared to Fast Ethernet, improving performance for large file transfers and media streaming across local devices. The metal desktop housing provides stable placement and passive cooling, while energy-efficient features help reduce power draw during periods of low activity.

Suitable for

• Small office and home network port expansion
• Connecting desktop PCs, network printers and NAS drives
• Adding wired connections for smart home hubs and media players
• Temporary network setups for meetings or workshops

Key specifications

• Number of ports: 5 Gigabit Ethernet (10/100/1000 Mbps) RJ-45
• Switch type: Unmanaged, plug-and-play
• Cadence: Auto-negotiation and Auto-MDI/MDIX support
• Throughput: Line-speed switching on all ports
• Form factor: Desktop metal housing, fanless design
• Power: External power adapter, energy-efficient operation
• Noise: Silent operation (no fan)

How to use

Place the switch on a stable surface near your network devices and connect the external power adapter to an appropriate outlet. Use standard Ethernet cables to link your router or modem to one of the switch ports and connect other devices to the remaining ports. The unit will automatically detect link speed and duplex settings. No management interface or software configuration is required; devices on the local network will communicate through the switch immediately after cabling and power-up.

Usage recommendations

For optimal performance, use quality Cat5e or Cat6 Ethernet cables and connect directly to Gigabit-capable ports on devices. Avoid blocking ventilation around the metal housing and place the switch away from sources of excessive heat or moisture. If large numbers of devices or advanced traffic control are needed, consider a managed switch or a model with more ports to match network requirements.
