Hardware Description
This section mainly describes the hardware of the 24 10/100/1000TX plus 4 Mini
GBIC Web Managed Switch and gives a physical and functional overview on the
certain switch.
Physical Dimension
24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch’s physical dimensions
is
440mm x 161mm x 44mm (Lx W x H).
Front Panel
The Front Panel of the 24 10/100/1000TX plus 4 Mini GBIC Web Managed
Switch consists of 24x 10/100/1000 Base-TX RJ-45 ports (Auto MDI/MDIX) and 4
Mini GBIC slots which can insert the Mini Gigabit Fiber module (optional). The
LED Indicators are also located on the front panel of the switch.
The Front panel of 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch
RJ-45 Ports (Auto MDI/MDIX): 24x 10/100/1000 N-way auto-sensing for
10Base-T or 100Base-TX or 1000Base-T connections.
In general,
MDI
means connecting to another Hub or Switch while
MDIX
means connecting to a workstation or PC. Therefore,
Auto MDI/MDIX
would
allow connecting to another Switch or workstation without changing
non-crossover or crossover cabling.

4 MINI GBIC slot: 4 slots for inserting the mini GBIC module that is optional.
Reset: Press the reset button for 2~5 seconds to reboot the switch or over 5
seconds to load factory default and reboot the switch.
LED Indicators
The LED Indicators display real-time information of systematic operation status.
The following table provides descriptions of LED status and their meaning.

Rear Panel
The 3-pronged power plug is located at the rear Panel of the 24 10/100/1000TX
plus 4 Mini GBIC Web Managed Switch as shown in figure. The switch will work
with AC in the range of 100-240V AC, 50-60Hz.
The Rear Panel of 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch
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 Pads
A. Make sure mounting surface on the bottom of the switch is grease and dust
free.
B. Remove adhesive backing of Rubber Pads.
C. Apply the Rubber Pads to each corner on the bottom of the switch and these
footpads can prevent the switch from shock/vibration.
Rack-mounted Installation
The 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch come with a
rack-mounted kid and can be mounted in an EIA standard size/19-inch Rack. The
11
switch can be placed in a wiring closet with other equipment.
Perform the following steps to rack mount the switch:
1. 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.
2. After attached mounting brackets, position the 24 10/100/1000TX plus 4 Mini
GBIC Web Managed switch 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.
[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.
12
Network Application
This section provides few samples of network topology in witch the switch is used.
In general, the 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch is
designed as a segment switch. That is, with its large address table (8K MAC
address) and high performance, it is ideal for interconnecting networking
segments.
PC, workstations and servers can communicate each other by directly connecting
with 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch. The switch
automatically learns nodes address, which are subsequently used to filter and
forward all traffic based on the destination address.
By using Uplink port, the switch can connect with another switch or hub to
interconnect other small-switched workgroups to form a larger switched network.
Meanwhile, you can also use fiber ports to connect switches.
Small Workgroup
The 24 10/100/1000TX plus 4 Mini GBIC Web Managed Switch can be used as a
standalone switch for personal computers, server and printer server which are
directly connected to form a small workgroup.
13
Segment Bridge
For enterprise networks where large data broadcasts are constantly processed,
this switch is an ideal solution for department users to connect to the corporate
backbone.
In the illustration below, two Ethernet switches with PCs, print server, and local
server attached, are both connect 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.

Web-Based Management
This section introduces the configuration and functionality of the Web-Based
management of the certain switch.
About Web-based Management
On the CPU board of the switch there is an embedded HTML web site residing in
flash memory, which offers advanced management features and allow users to
manage the switch from anywhere in the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 5.0. And, it is applied
with Java Applets for reducing network bandwidth consumption, enhance access
speed and present an easy viewing screen.
[NOTE]
By default, IE5.0 or later version does not allow Java Applets to activate
sockets. In fact, the user has to explicitly modify the browser setting to enable
Java Applets to operate network ports.
