Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a
network, eliminated congestion problems inherent with Carrier Sense multiple
access with Collision Detection ( CSMA/CD ) protocol, and greatly reduced
unnecessary transmissions.
This revolutionized networking. irst, by allowing two-way, simultaneous
transmissions over the same port ( ull-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 store-and-forward
technology to inspect each packet and intercept corrupt or redundant data.
Switching eliminated unnecessary transmission that slows the network. Address-
learning was employed to replace the inefficient receiving port.
Auto-negotiation regulates the speed and duplex of each port, based on the
capability of both devices. low-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 network applications involving legacy equipment. Disabling
the auto-negotiation is accomplished by fixing the speed or duplex of a port.
Ethernet Switching Technology supplied 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 new way of thinking to networking.
Hardware Description
This Section describes the hardware of the SmartGST-2402M and gives a physical and
functional overview of this Switch.

Rear Panel
The 3-pronged power plug and ventilation fan are located at the rear Panel of the
SmartGST-2402M as shown in igure 2-2. The Switch will work with AC in the
range 100-240V AC, 50-60Hz.

Desktop Installation
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.
Attaching 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 eet.
C. Apply the Rubber eet to each corner on the bottom of the Switch. These
footpads can protect the Switch from shock and vibration.

Rack mounted Installation
The SmartGST-2402M comes with a rack-mounting kit and can be mounted in an
EIA standard sized, 19-inch Rack. The Switch can be placed in a wiring closet with
other equipment.
Perform the following steps to rack mount the switch:
A. Align one bracket 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 you’ve attached both mounting brackets, position the SmartGST-2402M 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. Mount the SmartGST-2402M in a standard 19-inch Rack
Note: or proper ventilation, allow about at least 4 inches ( 10 cm ) of clearance on the
front and 3.4 inches ( 8 cm ) on the back of the Switch. This is especially important
for enclosed rack installation.

Power On
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 in
the Switch works with AC in the voltage range 100-240VAC, frequency 50~60Hz.
Check the power indicator on the front panel to see if power is properly supplied.
Network Application
This section provides you a few samples of network topology in which the Switch is
used. The SmartGST-2402M is designed as a segment switch. With its large
address table (6000 MAC addresses) and high performance, it is ideal for
interconnecting networking segments.
You can use the SmartGST-2402M to interconnect PCs, workstations, and servers
to each other by connecting these devices directly to the Switch. The switch
automatically learns node addresses, which are subsequently used to filter and
forward all traffic based on the destination address.
By using the Uplink feature, the Switch can connect with another switch or hub to
interconnect each of your switched workgroups forming a larger switched network.
Also you can also use the expansion port to connect switches for great distances.
The distance between two switches via fiber cable can be up to 10 Kilometers
(Gigabit LX port with Single Mode fiber).
Small Workgroup
The SmartGST-2402M can be used to create a small workgroup by directly
connecting personal computers, servers, and printer servers.

Segment Bridge
In enterprise networks where large data broadcasts are constantly processed, this
switch is perfect for department users connecting to the corporate backbone.
In the illustration below, two Ethernet switches with PCs, a print server, and a local
server attached, are both connected to the SmartGST-2402M. Each device in this
network can communicate with the others through the SmartGST-2402M.
Connecting servers to the Switch allows other users to access the server’s data.
