1. I troductio
Welcome to the World of Network Switching. n modern business,
communication and information sharing are fundamental to success.
Computer networks have proven to be one of the fastest ways of
communication.
The SmartGST-2402 is a multi-port Switch that can be used to build high-
performance switched workgroup networks. t is a store-and-forward device
that offers low latency for high-speed networking and is targeted at
workgroup, department, or backbone computing environments.
Figure 1-1. SmartGST-2402
The SmartGST-2402's “store-and-forward“ switching scheme allows the
switch to auto-learn and store source address in an 8K-entry MAC address
table.
MDI (Medium Dependent nterface) Port is also called an "uplink port". The
MD port does not cross the transmission and reception lines, which is done
by the regular ports (MD -X ports) that connect to end stations. n general,
MDI means connecting to another Hub or Switch while MDIX means
connecting to a workstation or PC. Therefore, Auto MDI/MDIX means that
you can connect to another Switch or workstation without changing non-
crossover or crossover cabling.
The SmartGST-2402 has twenty four auto-sensing 10/100Base-TX RJ-45
ports plus one module slot for optional dual port 100Base-FX, 1000T, and
1000SX/LX Mini GB C modules. This enables hi

Ether et Switchi g Tech ology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with CSMA/CD (Carrier
Sense multiple access with Collision Detection) protocol, and greatly reduced
unnecessar
y
transmissions.

This revolutionized networking. First, by allowing two-way, simultaneous
transmissions over the same port (Full-duplex), which essentially doubled the
bandwidth. Second, by reducing the collision domain to a single switch-port,
which eliminated the need for carrier sensing. Third, by using the store-and-
forward technology’s approach of inspecting each packet to intercept corrupt
or redundant data. By employing address learning, this switching eliminated
unnecessary transmission that slowed the network.
Auto-negotiation regulates the speed and duplex of each port, based on the
capability of both devices. Flow-control allows transmission from a 100Mbps
node to a 10Mbps node without loss of data. Auto-negotiation and flow-control
may need to be disabled for some networking operations involving legacy
equipment. Disabling the auto-negotiation is accomplished by fixing the speed
or duplex of a port.
Ethernet Switching Technology supplies higher performance at lower costs
than other solutions. Wider bandwidth, no congestion, and the reduction in
traffic is why switching is replacing expensive routers and inefficient hubs as
the ultimate networking solution. Switching brings a whole new way of thinking
to networking.

2. Hardware Descriptio
This Section describes the hardware of the SmartGST-2402 and gives a
physical and functional overview of this switch.
The physical dimensions: 440mm x 161mm x 44mm (L x W x H)
Fro t Pa el
The Front Panel of the SmartGST-2402 consists of twenty-four 10/100Base-
TX RJ-45 ports (Auto MD /MD X) and one expansion slot. The LED ndicators
are also located on the front panel of the Switch.

Desktop I stallatio
Set the Switch on a sufficiently large flat space with a power outlet nearby.
The surface where you put your Switch should be clean, smooth, level and
sturdy. Make sure there is enough clearance around the Switch to allow
attachment of cables, power cord and allow air circulation.
Attachi g Rubber Feet
A. Make sure mounting surface on the bottom of the Switch is grease and
dust free.
B. Remove adhesive backing from your Rubber Feet.
C. Apply the rubber feet to each corner on the bottom of the Switch. These
footpads can protect the Switch from shock/vibration.
Figure 2 4 Attaching Rubber Feet to each corner on the bottom of the Switch

Rack-mou ted I stallatio
The SmartGST-2402 comes with a rack-mounting kit and can be mounted in
any E A standard size, 19" Rack. The Switch can be placed in a wiring closet
with other equipment.
Perform the following steps to rack mount the switch:
A. Position one bracket to align with the holes on one side of the switch and
secure it with the smaller bracket screws. Then attach the remaining
bracket to the other side of the Switch.
Figure 2-4. Attach mounting brackets with screws
B. After attaching mounting brackets, position the SmartGST-2402 in the
rack by lining up the holes in the brackets with the appropriate holes on
the rack. Secure the Switch to the rack with a screwdriver and the rack-
mounting screws.

Figure 2-5. Mounting the Switch in an E A standard 19" Rack
Note: For proper ventilation, allow about at least 4" (10 cm) of clearance on
the front and 3.4" (8 cm) on the back of the Switch. This is especially
important for enclosed rack installations.
Power O
Connect the power cord to the power socket on the rear panel of the Switch.
The other side of power cord connects to the power outlet. The internal power
supply of the Switch works with voltage range of AC in the 100-240VAC,
frequency 50~60Hz.
Check the power indicator on the front panel to see if power is properly
supplied.

3. Network Applicatio
This section provides a few samples of network topology in which the Switch
is used. The SmartGST-2402 is designed as a segment switch. With its large
address table (8k MAC address) and high performance, it is ideal for
interconnecting networking segments.
PC, workstations, and servers can communicate with each other by directly
connecting with SmartGST-2402. The switch automatically learns node
addresses, which are subsequently used to filter and forward all traffic based
on the destination address.
By using any port as an uplink port, the Switch can connect with another
switch or hub and interconnect other small-switched workgroups to form a
larger switched network. Switches can also be interconnected using the fiber
port. The distance between two switches via fiber cable can be up to 2
kilometers (Multi-Mode fiber) or 30 kilometers (Single Mode fiber).
Small Workgroup
The SmartGST-2402 can be used as a standalone switch to which personal
computers, servers, and/or printer servers, are directly connect to form a
small workgroup.

Figure 3-1. Small Workgroup Application
Segme t Bridge
This switch is an ideal solution for departmental users in corporate backbones
where large data broadcasts are constantly broadcast.
n the illustration below, two Ethernet switches with PCs, a print server, and a
local server are all connected to the Switch. All the devices in this network can
communicate with each other through the Switch. Connecting servers to the
Switch allow other users to access the data on server.

Co ecti g to the Switch
The Console port is a female DB-9 connector that enables a connection to a
PC or terminal for monitoring and configuring the Switch. Use the supplied
RS-232 cable to connect a terminal or PC to the Console port.
The Console configuration (out of band) allows you to set the Switch for
"remote terminal" as if the console terminal were directly connected to it.
