Switch Netgear GS348 48-port Gigabit Ethernet unmanaged switch, 48x 1Gbps copper ports

Netgear GS348 is a 48-port Gigabit Ethernet unmanaged switch that provides forty‑eight 1 Gbps copper ports for wired network connectivity. Designed for plug‑and‑play deployment, the switch expands LAN capacity in offices, meeting rooms, server closets and small data centers without the need for configuration. It supports standard Gigabit Ethernet speeds to connect computers, printers, NAS devices and wireless access points, offering consistent wired throughput and simplified installation.

Advantages

The unmanaged design allows immediate use after powering and connecting devices, eliminating setup overhead. Forty‑eight gigabit copper ports deliver high port density for growing networks while maintaining predictable performance for common business and SMB workloads. The metal chassis contributes to stable operation in rack or desktop placements, and the compact profile helps integrate the switch into existing network racks or shelves. Standard Ethernet compatibility ensures wide device support and straightforward cabling.

Suitable for

• Expanding wired LAN in small to medium offices
• Connecting desktop PCs, VoIP phones and printers
• Linking NAS units and backup appliances to the network
• Providing wired ports for wireless access points and IP cameras
• Edge aggregation in small server rooms or lab environments

Key specifications

• Port count: 48 copper 10/100/1000 Mbps RJ‑45 ports
• Switching capacity and forwarding rate: typical for unmanaged Gigabit Ethernet layer‑2 switching
• Form factor: compact metal chassis suitable for desktop or rack placement
• Power: internal power supply (AC input), fanless or quiet operation depending on model thermal design
• Management: unmanaged, plug‑and‑play operation with no configuration interface
• Compatibility: supports standard Ethernet protocols and autonegotiation for connected devices

How to use

Place the switch on a stable surface or mount it in a rack using compatible brackets if available. Connect the included AC power cable to a grounded outlet and power on the device. Use standard Cat5e or Cat6 copper Ethernet cables to connect computers, printers, access points and storage devices to the RJ‑45 ports. The switch performs MAC address learning and forwards traffic automatically; no additional configuration is required. For best results, connect uplinks to other switches or routers using gigabit ports and ensure proper cable lengths and terminations.

Usage recommendations

For stable performance, use Cat5e or better cables and avoid running Ethernet alongside power lines for long stretches. Place the switch in a ventilated area with ambient temperatures within the manufacturer's specified range and plan port placement to allow future expansion without frequent re-cabling.
