Network switch Cudy GS105 — 5‑port Gigabit Ethernet (10/100/1000), black, 5 V DC power included

The 5-port Gigabit Ethernet switch provides five 10/100/1000 Mbps RJ-45 ports for fast, non-blocking data transfer. It supports automatic negotiation and IEEE 802.3x flow control to maintain reliable throughput and reduce congestion. The compact switch is suitable for expanding wired networks in homes, small offices and business environments, and can be used with IP cameras, VoIP phones and Wi‑Fi access points.

Advantages

The switch delivers gigabit speeds on all five ports for smooth file transfers and low-latency communication. Auto-negotiation ensures compatibility with 10/100/1000 Mbps Ethernet devices, while IEEE 802.3x flow control (full duplex) and backpressure (half duplex) help prevent packet loss during heavy traffic. Loop alarm support increases network reliability by alerting to link loops.

Key specifications

• Ports: 5 × 10/100/1000 Mbps RJ-45
• Data transfer: Non-blocking gigabit switching
• Auto-negotiation: Yes (10/100/1000 Mbps)
• Flow control: IEEE 802.3x (Full Duplex), backpressure (Half Duplex)
• Loop alarm: Supported
• Use cases: IP surveillance, VoIP, Wi‑Fi access point connectivity

How to use

Connect Ethernet cables from your devices (computers, IP cameras, VoIP phones, or Wi‑Fi APs) to the RJ-45 ports. The switch negotiates link speed automatically; power it on and the LEDs will indicate link/activity status. For most setups no configuration is required—simply place the switch between your router and local wired devices to increase available wired ports and improve local network throughput.

Recommendations

Place the switch in a ventilated location and use quality Ethernet cables (CAT5e or higher) to achieve gigabit speeds. Avoid creating physical loops in cable connections; enable loop detection or use the loop alarm feature if available in your network design.
