Δικτυακός διακόπτης QOLTEC 52247 5 x θύρες RJ45 1000 Mbit/s Gigabit unmanaged

QOLTEC 52247 is a compact unmanaged Gigabit network switch with five RJ45 ports supporting 1000 Mbps per port. The device is designed for straightforward expansion of wired LAN connections in small offices, home networks and workstations where additional Ethernet ports are required. As an unmanaged plug‑and‑play switch, it delivers full‑duplex Gigabit throughput for connected devices without configuration, offering a simple way to increase wired bandwidth and reduce network congestion for desktop PCs, printers, IP cameras and other Ethernet devices.

Advantages

The switch provides five full Gigabit ports that support automatic MDI/MDIX crossover, eliminating the need for dedicated crossover cables. Its unmanaged design requires no setup or management interfaces, enabling immediate operation after physical connection and power‑up. Energy‑efficient operation reduces power consumption during idle periods, while metal and plastic housing options provide compact durability for desktop or shelf placement. LED indicators for link/activity and speed make status monitoring intuitive.

Suitable for

• Expanding wired connections in small offices and home networks
• Connecting desktops, NAS, IP cameras and network printers
• Creating a simple workstation LAN without configuration
• Temporary networking for events, workshops or test environments

Key specifications

• Number of ports: 5 × RJ45
• Port speed: 10/100/1000 Mbps per port (Gigabit Ethernet)
• Operation: Unmanaged, plug‑and‑play
• Duplex: Full‑duplex and half‑duplex support with auto‑negotiation
• Auto MDI/MDIX: Supported on all ports
• LED indicators: Link/activity and speed per port
• Form factor: Desktop/shelf‑mountable compact unit
• Power: External power adapter (included)

How to use

Place the switch on a stable surface near your router or main network point and connect the included power adapter to a standard outlet. Use Ethernet cables to connect each RJ45 port to computers, network storage, printers or other Ethernet devices; the ports will auto‑negotiate speed and duplex. Link and activity LEDs indicate connection status and data transfer. No software configuration is required; devices will obtain network access through the existing LAN and DHCP server, if present.

Recommendations

For best performance, use Cat5e or higher quality Ethernet cables to achieve stable Gigabit speeds. Place the switch in a ventilated area away from direct heat sources. When connecting devices with heavy sustained traffic, distribute workloads across ports and avoid daisy‑chaining multiple unmanaged switches to minimise collision domains and maintain optimal throughput.
