GEU-0521 5-Port Gigabit Switch, 1 x SFP Fiber Uplink

The LevelOne GEU-0521 is a compact 5-port Gigabit switch designed to bridge copper and fiber networks in small office, workgroup and edge deployments. With 4 x 10/100/1000BASE-T RJ45 ports and 1 x 1000BASE-X SFP slot, it enables flexible copper-to-fiber conversion for extending network reach to remote rooms, buildings or wiring closets.

Delivering non-blocking wire-speed switching and support for 9K jumbo frames, the GEU-0521 is well suited for high-bandwidth applications such as large file transfers, IP surveillance backhaul and server/NAS connections. IEEE 802.3x Flow Control helps reduce packet loss and maintain reliable data transmission, while auto-negotiation and auto-MDI/MDIX on all copper ports simplify cabling and uplink connections.

The switch supports MAC address auto-learning and auto-aging to maintain stable forwarding performance in growing networks. Its compact housing supports both desktop and wall mounting, making it easy to deploy in space-constrained environments, wiring closets or equipment rooms. As an unmanaged plug-and-play device, no software configuration is required—simply connect the Ethernet and fiber cables, power it up, and the GEU-0521 immediately begins forwarding traffic.
