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.

2.2 Rear Panel
The rear panel of the Switch indicates an AC inlet power socket which accepts input power from 100 to
240VAC, 50-60Hz.
Power Notice:
1. The device is a power-required device, it means, it will not work till it is powered. If your networks should
active all the time, please consider using UPS (Uninterrupted Power Supply) for your device. It will
prevent you from network data loss or network downtime.
2. In some area, installing a surge suppression device may also help to protect your switch from being
damaged by unregulated surge or current to the Switch or the power adapter.

3.1 Before start up
Before your installation, please refer to the followings for your cabling:
100Base-TX
All 100Base-TX ports come with auto-negotiation capability. They automatically support 100Base-TX and
10Base-T networks. Users only need to plug a working network device into one of the 100Base-TX ports,
then turn on the Switch. The port will automatically runs in 10Mbps, 20Mbps, 100Mbps or 200Mbps after
the negotiation with the connected device.
1000Base-T
The Switch are with two Gigabit port. This two ports support 10Mbps, 100Mbps and 1000Mbps speed and
also are full-duplex supported.
Cabling
Each 10/100/1000Base-T ports use RJ-45 sockets -- similar to phone jacks -- for connection of
unshielded twisted-pair cable (UTP). The IEEE802.3ab Gigabit Ethernet standard requires 4-pair
Category 5/5e UTP cable. IEEE 802.3u Fast Ethernet standard requires Category 5 UTP for 100Mbps
100Base-TX. 10Base-T networks can use Cat.3, 4, or 5 UTP (see table below). Maximum distance is
100meters (328 feet).
3. INSTALLATION
Port Type Cable Type Connector
10Base-T Cat 3, 4, 5, 2-pair RJ-45
100Base-TX Cat.5 UTP, 2-pair RJ-45
1000Base-T Cat. 5/5e UTP, 4-pair RJ-45
Any Ethernet devices like hubs/ PCs can connect to the Switch by using straight-through wires. The eight
10/100Mbps port and two 1000Base-T are auto-MDI/ MDI-X can be used on straight-through or crossover
cable.
3.2 Connecting end node, hub or switch
1. Place the Switch on a smooth surface or fasten the mounting brackets purchased separately with the
provided screws in a standard 10”/19” rack.
2. Connect the power cord to the power inlet socket of Switch and the other end into the local power
source outlet.
3. Connect other switch or PC to one port of the GSD-1020 using Category 3/4/5 UTP/STP cabling.
4. Connect another switch or PC to the other port of Switch by following the same process as described
in Step3.

Figure 3. End node, Hub or Switch connection
Notice:
Cable distance for Switch
The cable distance between Ethernet Switch and hub/PC should not exceed 100 meter for UTP/STP
cable.
Make sure the wiring is correct
It can be used Category 3/4/5 cable in 10 Mbps operation. To reliably operate your network at
100Mbps and 1000Mbps, you must use an Unshielded Twisted-Pair (UTP) Category 5 cable, or
better Data Grade cabling. While a Category 3 or 4 cable may initially seem to work, it will soon
cause data loss.
3.3 Connecting to Network Backbone or Server
Connect to the Gigabit Ethernet ports with Category 5 copper cable for uplinking to a network backbone
or network server. These ports operate at 1000Mbps in full-duplex mode. A valid connection is indicated
when the Link LED is light.

4. SWITCH OPERATION
Address Table
The Giga Switch is implemented with an address table. This address table composed of many entries. Each
entry is used to store the address information of some node in network, including MAC address, port no, etc.
This information comes from the learning process of Ethernet Switch.
Learning
When one packet comes in from any port, the Giga Switch will record the source address, port no. and the
other related information in address table. This information will be used to decide either forwarding or filtering
for future packets.
Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address
besides the source address learning. The Ethernet Switching will lookup the address-table for the destination
address. If not found, this packet will be forwarded to all the other ports except the port which this packet
comes in. And these ports will transmit this packet to the network it connected. If found, and the destination
address is located at different port from this packet comes in, the Ethernet Switching will forward this packet to
the port where this destination address is located according to the information from address table. But, if the
destination address is located at the same port with this packet comes in, then this packet will be filtered.
Thereby increasing the network throughput and availability
Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and Forward Ethernet Switching
stores the incoming frame in an internal buffer, do the complete error checking before transmission. Therefore,
no error packets occurrence, it is the best choice when a network needs efficiency and stability.
The Ethernet Switch scans the destination address from the packet-header, searches the routing table
provided for the incoming port and forwards the packet, only if required. The fast forwarding makes the switch
attractive for connecting servers directly to the network, thereby increasing throughput and availability.
However, the switch is most commonly used to segment existing hubs, which nearly always improves overall
performance. A Ethernet Switching can be easily configured in any Ethernet network environment to
significantly boost bandwidth using conventional cabling and adapters.
Due to the learning function of the Ethernet switching, the source address and corresponding port number of
each incoming and outgoing packet are stored in a routing table. This information is subsequently used to filter
packets whose destination address is on the same segment as the source address. This confines network
traffic to its respective domain and reduces the overall load on the network.
The Giga Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.
Auto-Negotiation
The STP ports on the GSD-1020 switch have built-in "Auto-negotiation". This technology automatically sets
the best possible bandwidth when a connection is established with another network device (usually at Power
On or Reset). This is done by detecting the modes and speeds at the second of both device is connected and
capable of, Both 10Base-T and 100Base-TX devices can connect with the port in either Half- or Full-duplex
mode. 1000Base-T can only connected in Full-duplex mode.

5. TROUBLESHOOTING
This chapter contains information to help you solve problems. If Giga Switch is not functioning properly, make
sure the Ethernet Switch was set up according to instructions in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Giga Switch
Some stations can not talk to other stations located on The other port
Solution:
The address table may contain older information than of the address table of that node. Please power
down to refresh the address information.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is set to full duplex and the
partner is set to half duplex, then the performance will be poor.
