LevelOne GSW-2472TGX
1. Introduction
Welcome to the World of Network Switching. In the modern business society,
communication and information sharing are fundamental to our life. And computer
networks have proven to be one of the fastest ways of communication.
LevelOne GSW-2472TGX, 24Fast/2 Gigabit combo Web 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.
LevelOne GSW-2472TGX features a “store-and-forward “ switching scheme. This
allows the switch to auto-learn and store source address in a 6K-entry MAC address
table.
LevelOne GSW-2472TGX supports Auto MDI/MDIX.MDI (Medium Dependent
Interface) Port is also called an "uplink port". The MDI port does not transmit cross and
receive lines, which is done by the regular ports (MDI-X ports) that connect to end
stations. 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.
LevelOne GSW-2472TGX has 24 auto-sensing 10/100Base-TX RJ-45 ports and 2
auto detect Giga port for higher connection speed.

2. Hardware Description
This Section describes the hardware of GSW-2472TGX, and give a physical and
functional overview of this Switch.
The physical dimensions: 440mmx 161mm x 44mm (L x W x H)
FrontPanel
The Front Panel of GSW-2472TGX consists of 24x 10/100Base-TX RJ-45 ports (Auto
MDI/MDIX) and 2 auto detect Giga port which could be Copper Gigabit port or Mini
Gigabit Fiber module (optional). The LED Indicators are also located on the front panel
of the Switch.
Figure 2-1. The Front panel of GSW-2472TGX
RJ-45 Ports (Auto MDI/MDIX): 24x 10/100 N-way auto-sensing for 10Base-T or
100Base-TX connections.
[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. ]
2 Giga port: 2 auto detect Giga port—UTP or fiber. Giga fiber is the mini GBIC module
that is optional.
[Note] When you install the Mini GBIC into the switch, you must disconnect the giga
5

24Fast /2 Gigabit Ethernet combo Web Smart Switch
copper connection if you have connected device with it. Otherwise, the switch will not
detect the Mini GBIC that you have installed. While you using giga copper port or Mini
GBIC port, only one of them will work, ex: when giga copper port is connecting, then
Mini GBIC is disabling.

RearPanel
The 3-pronged power plug is located at the rear Panel of GSW-2472TGX as shown in
Figure 2-3. The Switch will work with AC in the range 100-240V AC, 50-60Hz.
Figure 2-3. The Rear Panel of GSW-2472TGX
Desktop Installation
Set the Switch on a sufficiently large flat space with a power outlet nearby. The surface
where you put the 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
7

24Fast /2 Gigabit Ethernet combo Web Smart Switch
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
GSW-2472TGX come with a rack-mounted kid 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.
Figure 2-5. Attach mounting brackets with screws
B. After attached both mounting brackets, position GSW-2472TGX 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 2-6. Mount the Switch in an EIA standard 19-inch Rack
[Note] For 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 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.
