Level One GEU-1621 User Manual
GEU-1621 Version: 2
16-Port Gigabit Switch
The GEU-1621 is equipped with 16 Gigabit ports that lead you to a real Gigabit connections. Users are able
to transfer large and high bandwidth-needed files faster, and hence get a real improvement of efficiency.
Offers a fast and reliable networkThe store-and-forward architecture filters errors and forwards packets in a
non-blocking environment. Flow control ensures the correctness of data transmitting. The IEEE 802.3x and
backpressure flow control mechanisms work respectively for full and half duplex modes.
Power Saving FeaturesThe GEU-1621 supports IEEE 802.3az Energy Efficient Ethernet to provide powersaving benefits without compromising the performance. The switch automatically enters the sleep mode, if
there is no link activity detected, using less energy than idling at full power.
Easy Installation and MaintenanceThe switch supports Nway auto-negotiation protocol to detect the
networking speed (10/100/1000 Mbps) and the duplex modes (Full/Half) automatically. Auto-MDI/MDI-X
function eliminates the effort to use crossover cables. Diagnostic LEDs are provided to get real-time
information of the connection status and network.
