Chapter 2Hardware Description
This section mainly describes the hardware of the 24 10/100/1000T with 4 1000SFP
shared cage SNMP Managed Switch.
2.1 Physical Dimension
The physical dimensions of the 24 10/100/1000T with 4 1000SFP shared cage SNMP
Managed Switch is 440mm(W) x 161mm(D) x 44mm(H)
2.2 Front Panel
The Front Panel of the 24 10/100/1000T with 4 1000SFP shared cage SNMP Managed
Switch consist of 24 x auto-sensing 10/100/1000Mbps Ethernet RJ-45 ports (automatic
MDI/MDIX), 4 Mini GBIC ports, and the LED indicators are also located on the front
panel of the switch.
Front Panel of the 24 10/100/1000T with 4 1000SFP shared cage SNMP Managed Switch
RJ-45 Ports (Auto MDI/MDIX): 24 10/100/1000 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 means that you can
connect to another Switch or workstation without changing non-crossover or
crossover cabling.

12
4 Mini-GBIC ports: The appropriate replaceable Mini-GBIC ports are available with
a variety of different transmitter and receiver types, allowing users to select the
appropriate transceiver for each link to provide the required optical reach over
the available optical fiber type. Ports 21 ~ 24 are the four combo ports which
consist of one RJ-45 port and one mini-GBIC port each. Traditional RJ-45 ports
can be used for uplinking wide-band paths in short distance (<100m), or the
appropriate replaceable mini-GBIC ports can be used for the application of
wide-band uplinking and long distance transmissions to fit the flexible field request.
2.3 Rear Panel
The 3-pronged power plug is located at the Rear Panel of 24 10/100/1000T with 4
1000SFP shared cage SNMP Managed Switch as shown in the figure below. The Switch
will work with AC in the range of 100-240V AC, 50-60Hz.

Chapter 3Hardware Installation
3.1 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 air
circulation.
Attaching Rubber Feet
1. Make sure mounting surface on the bottom of the Switch is grease and dust free.
2. Remove adhesive backing from your Rubber Feet.
3. Apply the Rubber Feet to each corner on the bottom of the Switch. These footpads
can prevent the Switch from shock/vibration.
3.2 Rack-mounted Installation
The Switch comes with a rack-mounted kit and can be mounted in an EIA standard size,
19-inch Rack. It can be placed in a wiring closet with other equipment.
Perform the following steps to rack-mount the switch:
A. Position one plate to align with the holes on one side of the hub and secure it with
the smaller plate screws. Then, attach the remaining plate to the other side of the
Switch.
Attach mounting plates with screws

15
B. After attaching both mounting plates, position the Switch in the rack by lining up the
holes in the plates with the appropriate holes on the rack. Secure the Switch to the
rack with a screwdriver and the rack-mounting screws.
Mount the Switch in an EIA standard 19-inch Rack
Note: For proper ventilation, allows 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.
3.3 Cabling
Use four twisted-pair, Category 5e or above cabling for RJ-45 port connection. The
cable between the switch and the link partner (switch, hub, workstation, etc.) must
be less than 100 meters (328 ft.) long.
Fiber segment using single-mode connector can be applied to standard (such as
9/125 µm, 9.5/125 µm, or 10/125 µm) single-mode fiber cable. User can connect two
devices in the distance up to 30km.
Fiber segment using multi-mode connector can be applied to standard (such as 50
or 62.5/125 µm) multi-mode fiber cable. User can connect two devices up to 2km
distances.

16
To connect the transceiver and LC cable, please follow the steps shown below:
First, insert the transceiver into the SFP module. Notice that the triangle mark is the
bottom of the module.

Second, insert the fiber cable of LC connector into the transceiver.

Chapter 4 Network Application
This section provides you a few samples of network topology in which the switch is used.
In general, the 24 10/100/1000T with 4 1000SFP shared cage SNMP Managed Switch is
designed to be used as a desktop or segment switch.
4.1 Desktop Application
The 24 10/100/1000T with 4 1000SFP shared cage SNMP Managed Switch is designed
to be a desktop size switch that is an ideal solution for small workgroup. The Switch can
be used as a stand-alone switch to which personal computers, server, printer server are
directly connected to form small workgroup.
4.2 Segment Application
For enterprise networks where large data broadcast are constantly processed, this
switch is suitable for department user to connect to the corporate backbone.

18
User can connect PCs, workstations, and servers to each other via the 24 10/100/1000T
with 4 1000SFP shared cage SNMP Managed Switch. All the devices in this network can
communicate with each other. Connecting servers to the backbone switch allow other
users to access the data of server.
The switch automatically learns node address, which are subsequently used to filter and
forward all traffic based on the destination address. User can use any of the RJ-45 port
of the 24 10/100/1000T with 4 1000SFP shared cage SNMP Managed Switch to connect
with another Switch or Hub to interconnect each of user‟s small-switched workgroups to
form a larger switched network.

19
Chapter 5 Console Management
5.1 Connecting to the Console Port
Use the supplied RS-232 cable to connect a terminal or PC to the console port. The
connected terminal or PC must support the terminal emulation program.
Connecting the switch to a terminal via RS-232 cable
5.2 Login in the Console Interface
When the connection between Switch and PC is ready, turn on the PC and run a terminal
emulation program or Hyper Terminal and configure its communication parameters to
match the following default characteristics of the console port:
Baud Rate: 9600 bps
Data Bits: 8
Parity: none
