Hardware Description
This section mainly describes the hardware of the 4 10/100/1000T + 1 Mini-GBIC
Web Managed Switch, and gives a physical and functional overview on certain
switch.
Physical dimension
The 4 10/100/1000T + 1 Mini-GBIC Web Managed Switch physical dimension is
165 x 100 x 32.5 mm (W x D x H).
Front Panel
The Front Panel of the 4 10/100/1000T + 1 Mini-GBIC Web Managed Switch
consists of LED Indicators and a reset button. Please refer to LED Indicator
section for LED description.
Reset button: It provides an easy way for user to reset the configuration
back to the default settings. Press the button more than 5 seconds, and then
the switch will restart and set all configurations back to the default settings.

5
Rear Panel
The rear panel consists of the 4 10/100/1000Base-TX RJ-45 port, one Mini GBIC
slot, and DC Power Jack as shown in the figure below. The switch will work with
DC in the range of 12V/0.8A.
The Rear Panel of 4 10/100/1000T + 1 Mini-GBIC Web Managed Switch
RJ-45 Ports (Auto MDI/MDIX): 4x 10/100/1000 N-way auto-sensing for
10Base-T, 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.
Mini GBIC slot: The appropriate replaceable Mini-GBIC port is 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. There is one LED
indicator—LNK/ACT—for Mini-GBIC port on the front panel.
LED Indicators
The LED Indicators display the real-time information of systematic operation
status. Please see definition of the LED indicators as follows.

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 Pads.
C. Apply the Rubber Feet to each corner on the bottom of the switch. These
footpads can prevent the switch from shock/vibration.
Power On
Connect the power adaptor to the power jack on the rear panel of the switch. The
other side of power adaptor is connected to the power outlet. The external power
supply in the switch works with DC power in 12V/0.8A. Please check with the
power indicator on the front panel to see if power is properly supplied.

8
Network Application
This section provides user a few samples of network topology in witch the switch
is used. In general, the 4 10/100/1000T + 1 Mini-GBIC Web Managed Switch is
designed as a segment switch. That is, with its address table (8000 MAC address)
and high performance, it is ideal for interconnecting networking segments.
PC, workstations, and servers can communicate each other by directly
connecting with 4 10/100/1000T + 1 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. The distance
between two switches via fiber cable depends on the type of fiber transceiver.
Small Workgroup
The 4 10/100/1000T + 1 Mini-GBIC Web Managed Switch can be used as a
standalone switch to which personal computers, server, printer server, are
directly connected to form small workgroup.
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.

9
Two 4 10/100/1000T + 1 Mini-GBIC Web Managed Switches with PCs, print
server, and local server attached, are both connected to the core switch. All the
devices in this network can communicate with each other through the 4
10/100/1000T + 1 Mini-GBIC Web Managed Switch. Connecting servers to the 4
10/100/1000T + 1 Mini-GBIC Web Managed Switch allows users accessing the
data on server. By using fiber ports to connect switches, the distance between
two switches depends on the type of fiber transceiver.

Web-Based Management
This section introduces the function of the 4 10/100/1000T + 1 Mini-GBIC Web
Managed Switch configuration.
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 on the network through a standard browser
such as Microsoft Internet Explorer.
The Web-Based Management supports Internet Explorer 6.0. And, it is applied
with Java Applets for reducing network bandwidth consumption, enhance access
speed and present an easy viewing screen.

VLAN Setting
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which would allow users to isolate network traffic, and therefore only the
members of the VLAN will receive traffic from the members of the same VLAN.
Basically, creating a VLAN from a switch is logically equivalent to reconnecting a
group of network devices to another Layer 2 switch. However, all the network
devices are still plugged into the same switch physically.
Assign the VLAN ID in number between 1 and 4095.
Group the members of VLAN by ticking the check box.
Click Apply to bring up the configuration interface as below.
Tick all check boxes by clicking ‘add all’ or remove all ticks by clicking ‘clear
all’.

16
There are 16 VLAN entries per page among 16 pages. To search the
specified VLAN, please type in the VLAN ID in the empty field beside the
label of ‘Quick Search Vlan Entry, Vlan ID:’ and then press ‘Search’.

VLAN Port Setting
Click VLANPortSetting to bring up the configuration interface for adjusting
the VID Setting.
PVID: Enter the Port VLAN ID.
Awareness: Enable the awareness so that ports will strip the VLAN tag from
received frames and insert the tag (contains PVID) into transmitted frames.
