SG80 is a gigabit Ethernet switch, of high performance and easy maintenance. The switch is dedicated to a high speed forward demand like schools, small business offices, tiny enterprises and other small places. With an attractive MINI desktop design, and 8 ports,it is particularly suitable for small-size network. It also provides 8 10/100/1000 Mbps auto-negotiation ports, and supports automatic MDI/MDIX. These gigabit ports can not only be used as ordinary ports, but can also cascade to other network devices throught UPLINK port. In full duplex mode, SG80 can be used to replace the 10, 100 Mbps switch, to solve the bottleneck problem of the server terminal connection.
