Network switch QOLTEC 52248 — 8 x RJ45 ports, 1000 Mbps

QOLTEC 52248 is a compact wired network switch offering eight RJ45 Gigabit ports, each supporting up to 1000 Mbps throughput. Designed for small offices, home networks and workgroups, the switch provides stable wired connectivity for multiple devices and supports file transfers, video streaming and VoIP traffic. The plug-and-play design requires no configuration, making it a practical choice to expand a local area network and consolidate wired connections.

Advantages

The device delivers full Gigabit speed on all eight ports to maintain high throughput between networked devices. Its compact metal/plastic housing and fanless design ensure low noise operation and simple placement on a desk or mounted in a small network cabinet. The switch offers auto-negotiation and auto-MDI/MDIX functionality for straightforward connection of computers, printers, NAS units and other Ethernet devices without manual cable type selection.

Suitable for

• Small office networks requiring reliable wired connections
• Home networking for streaming, gaming and smart home hubs
• Workgroups sharing large files or accessing a NAS
• VoIP phones and videoconferencing endpoints
• Temporary network expansion at events or meetings

How to use

Place the switch on a stable surface near your router or network devices and connect the included power adapter to a standard AC outlet. Use standard Ethernet cables to connect computers, printers, NAS devices or a router to any of the eight RJ45 ports. The switch operates in plug-and-play mode; LEDs indicate link status and activity. For optimal performance, connect high-bandwidth devices with Cat5e or higher-rated cables and avoid placing the unit in confined spaces that can restrict passive cooling.

Usage recommendations

For best results, use shielded or unshielded Cat5e/Cat6 cables for Gigabit links, position the switch in a ventilated area to maintain passive cooling, and connect devices that exchange large files or stream high-definition media directly to the switch to reduce wireless congestion. Regularly check LED status to ensure proper link activity and replace cables that show intermittent connectivity.
