LevelOne GEU-0521 / Switch / unmanaged / 4 x 10/100/1000 + 1 x Gigabit SFP / desktop, wall-mountable | GEU-0521
Product Features
- High-speed networking
The GEU-0521 provides an excellent solution for expanding your Gigabit network. By Gigabit speed, this product provides high flexibility and high bandwidth connectivity to servers, workstations and other attached devices. It enables you to save time transferring large files. - Auto-MDI/MDI-X
Every copper port can automatically sense your type of cable, so there is no need for crossover cables whether you are connecting this switch to another switch or to a computer. - Auto-negotiation
Every port can automatically sense if the connected network devices are running at 10 Mbps, 100 Mbps or 1000 Mbps and half/full-duplex mode, and adjust accordingly. - Non-blocking
This switch receives and forwards traffic seamlessly with its non-blocking wire-speed. Every port simultaneously supports up to 2000 Mbps of bandwidth in full-duplex mode. This feature provides full wire speed to the connected devices and allows you to run a smooth network. - Store and forward
By this function, this switch can maximize network performance while minimizing the propagation of bad network packets.
