Introduction
Welcome to the World of Network Switching.
In the modern business society, communication and information
sharing are fundamental to our lifestyle. And computer networks
have proven to be one of the fastest means of communication.
The LevelOne GSW-2470TGX Smart Switch is a multi-port Switch that
can be used to build high-performance switched workgroup
networks. This switch is a store-and-forward device that offers low
latency for high-speed networking. The Switch is targeted at
workgroup, department or backbone computing environment at SME
(small, medium enterprise) business.
Figure 1-1. The LevelOne GSW-2470TGX Smart Switch
The LevelOne GSW-2470TGX Smart Switch features a
“store-and-forward “switching scheme. This allows the switch to
auto-learn and store source address on 8K-entry MAC address
table.

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. 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, switching eliminated unnecessary transmission that slow the
network. By employing address-learning, which replaced the
inefficient receiving port.
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 require disablement for some
networking operations involves legacy equipment. Disabling the
auto-negotiation is accomplished by fixing the speed or duplex of a
port.
Ethernet Switching Technology supplied higher performance at
costs lower 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 brought a whole new way of thinking to networking.

Hardware Description
This Section mainly describes the hardware of the LevelOne
GSW-2470TGX Smart Switch, and gives a physical and functional
overview of this Module Switch.
The physical dimensions of the 24 TX Auto MDIX are:
440mmx 161mm x 44mm (L x W x H)
FrontPanel
The Front Panel of the24 TX Auto MDIX consists of 24x
10/100Base-TX RJ-45 ports and 2 Gigabit Copper ports. The LED
Indicators are also located on the front panel of the Switch.
Figure 2-1. The Front panel
RJ-45 ports (Auto MDI/MDIX): 24x 10/100Mbps auto-sensing
port for 10Base-T or 100Base-TX devices connection.
[In 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.]
2Gigabit Copper ports: 2x 100/1000Mbps auto-sensing port for
Full-duplex connection.

RearPanel
The 3-pronged power plug is located at the rear panel of the
LevelOne GSW-2470TGX Smart Switch as show in the Figure 2-3. The
Switch will work with AC in the range 100-240V AC, 50-60Hz.
Figure 2-3. The Rear Panel of the LevelOne GSW-2470TGX Smart Switch
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 Feet.
C. Apply the Rubber Feet to each corner on the bottom of the
Switch. These footpads can prevent the Switch from
shock/vibration.
Figure 2-4. Attaching Rubber Feet to each corner on the bottom of the Switch
Rack-mounted Installation
The 24TX Auto MDIX comes with a rack-mounted kit (Not a standard
option for this switch) and can be mounted in an EIA standard size,
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. 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.
B. After attached both mounting brackets, position the 24 Port 10/100
Auto MDIX 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.

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 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.

Connecting to the Switch (For Smart Switch
Model)
The Console port is a female DB-9 connector that enables a
connection to a PC or terminal for monitoring and configuring the
LevelOne GSW-2470TGX Smart Switch. Use the supplied RS-232
cable with a male DB-9 connector to connect a terminal or PC to the
Console port.
The Console configuration (out of band) allow you to set your Switch
to enable a user at a remote console terminal to communicate with
the 24TX Intelligent Switch as if the console terminal were directly
connected to it.
