Level One GEU-0521 User Manual
GEU-0521 Version: 2
5-Port Gigabit Switch, 1 x SFP
GEU-0521 is designed to make conversion between 10/100/1000Base-T and 1000Base-SX/LX Fiber
Ethernet. The overall network flexibility is enhanced, and the network efficiency is also improved to
accommodate and deliver high bandwidth applications. Providing 10Gbps internal switching fabric,
the GEU-0521 can handle an extremely large amount of data in a secure topology linking to a backbone or
high capacity servers. The GEU-0521 provides 4K MAC address table, 9K bytes JUMBO Frame, and offers
wire-speed packet transfer performance without risk of packet loss. The high data throughput of the device
makes it ideal for most Gigabit environments, especially for the network to be upgraded to a Gigabit
environment.
