1.2 About the Switch
The Ethernet Switch is equipped with unshielded twisted-pair (UTP) cable ports providing dedicated 10 or
100Mbps bandwidth. GSD-1020 supports MDI-X/ MDI convertible on each 10/100 port and 2 Gigabit Switch
port that can be used for uplinking to another switch. The dual speed ports use standard twisted-pair cabling
and are ideal for segmenting networks into small, connected sub-networks. Each 100M port can support up
to 200Mbps of throughput in full-duplex mode. Each 1000M port can support up to 2Gbps in Full-duplex
mode.
In addition, the Switch is also support 2 Ethernet Gigabit ports to uplink to a server or network backbone.
These Gigabit Switches are designed for Plug and Play installation, allows the network administrator to
simply connect the network and power cables and the Switching/bridging functions begin automatically.
The front panel of GSD-1020 provide LEDs for easy recognition of the switch operation status and for
troubleshooting. These LED indicators display the power status for the system and Link/Act, 100, full-duplex
for each10/100M port, Act, 1000/100, full-duplex for each Gigabit port.
