## Summary description

The LevelOne GEU-0521 is an unmanaged 5-port gigabit switch with 1 SFP port. It features 4 RJ-45 Ethernet ports supporting Gigabit Ethernet (10/100/1000) in full duplex mode. With a MAC address table of 4000 entries and a switching capacity of 1 Gbit/s, it ensures efficient data transfer. Compliant with IEEE networking standards, it is wall mountable for easy installation.

## Long description

LevelOne GEU-0521 is an unmanaged 5-port Gigabit Ethernet switch with four RJ-45 Gigabit (10/100/1000) ports and one SFP slot for 1000Base-SX/LX fiber connections. The device is designed to convert and connect copper-based Gigabit networks to fiber links, increasing network flexibility and supporting high-bandwidth applications. It supports a 4K MAC address table, 9K jumbo frames and a 10Gbps internal switching fabric to sustain high data throughput without packet loss, and is compatible with IEEE 802.3 family standards. The compact, wall-mountable metal housing and grey finish make it suitable for small office or closet installations.
Advantages
The GEU-0521 delivers wire-speed packet forwarding for Gigabit ports and fiber uplink, a 4K MAC address table for efficient switching, and 9K-byte jumbo frame support to improve throughput for large packets. The SFP slot enables flexible fiber connectivity (1000Base-SX/LX) to backbone links or high-capacity servers. Compliance with IEEE standards ensures interoperability with existing equipment.
Suitable for
 Small office or home office networks requiring Gigabit copper-to-fiber conversion
 Connecting Gigabit workstations or IP devices to a fiber backbone
 Edge switching where unmanaged, plug-and-play operation is preferred
 Deployments needing jumbo frame support for large data transfers

How to use
Mount the switch on a stable surface or wall using the mounting holes, connect power, then plug Ethernet cables from PCs, servers or other network devices into the RJ-45 ports. Insert a compatible 1000Base-SX or 1000Base-LX SFP module into the SFP slot and connect fiber optic cable to link to a backbone or remote switch. The unmanaged design requires no configuration; the switch performs auto negotiation on copper ports and forwards traffic according to learned MAC addresses.
Usage recommendations
Place the switch in a ventilated location away from direct heat sources. Use quality Cat5e or Cat6 cables for Gigabit links and follow proper fiber handling when installing SFP modules. For backbone connections choose the appropriate SFP module (SX for multimode, LX for single mode) and ensure matched transceivers at both ends.
