Chapter 1 Introduction to the Web Smart Switch
1.1 General Description
High Performance
The device is a powerful, high-performance Gigabit Ethernet switch with 8 10/100/1000 Mbps ports,
providing you a cost-effective, space-saving solution for expanding your network. The gigabit ports
can lead you to a real gigabit connection, making you be able to transfer high bandwidth-needed
files higher and faster in an easy way.
This device provides the easy management function through the Ethernet Web. The network
administrator can configure the status and the port function setting of the device through the
Web-Based UI. When installing the auto-discovery management tool helps network managers to
search and access those switches on LAN easily. Therefore, network managers can access
switches that support auto-discovery on LAN without memorizing IP address.
Smart Features
The device provides rich features including Link Aggregation, VLANs, IGMP Snooping, Port
Trunking, Spanning Tree, Security and other network management to meet the requirements
evolving medium and small-sized enterprises. QoS secures the bandwidth for some
bandwidth-demanded applications including VoIP or video conference. Additionally, IEEE 802.3az
Energy Efficient Ethernet ability is supported to promise operation in Low Power Idle Mode and
save power consumption.
Easy Installation and Management
This switch is plug & play and hassle-free in installation. Auto-MDI/MDI-X crossover on all ports
eliminates the need for crossover cables for connection to another switch or hub. Auto-Negotiation
on each port senses the link speed of a network device and intelligently adjusts for compatibility and
optimal performance. This switch also features diagnostic LEDs, which display the status and
activities of the network.
1.2 The Front Panel
The following figure shows the front panel of the switch.
The following table describes the port labels on the front panel.

The system is transmitting/receiving to/from a 1000 Mbps
Ethernet network.
Reset the switch to its factory default configuration via the RESET button. Press the RESET button
for three seconds and release. The switch automatically reboots and reloads its factory
configuration file. The RESET button is on the front panel of the switch.
1.4 The Rear Panel
The following figure shows the rear panel of the switch:
Power Receptacle
To be compatible with the electric service standards around the world, the switch is designed to
afford the power supply in the range from 100 to 240 VAC, 50/60 Hz. Please make sure that your
outlet standard to be within this range.
To power on the switch, please plug the female end of the power cord firmly into the receptacle of
the switch, the other end into an electric service outlet, and
the Switch power on or off. After the switch powered on, please check if the power LED is lit for a
use the POWER ON/OFF switch to have
normal power status.

1.5 Installation
This switch can be placed on your desktop directly, or mounted on the wall. Please refer to the
instructions for installation.
Before installing the switch, we recommend:
1. The switch is placed with appropriate ventilation environment. A minimum 25 mm space around
the unit is recommended.
2. The switch and the relevant components are away from sources of electrical noise such as
radios, transmitters and broadband amplifiers
3. The switch is away from environments beyond recommend moisture
Desktop Installation
1. Install the switch on a level surface that can support the weight of the unit and the relevant
components.
2. Plug the switch with the power cable of adaptor and plug the power adaptor to the power outlet.
Wall-mount Installation
The switch may be standalone, or mounted on wall. Wall mounting facilitate to an orderly
installation when you are going to install series of networking devices.
Procedures to Wall-mount the switch:
1. Screw the two screws provided with your Switch into the wall. Use screws with 6 mm ~ 8 mm (0.24" ~
0.31") wide heads. Do not screw the screws all the way in to the wall; leave a small gap between the
head of the screw and the wall.
2. Align the holes on the back of the Switch with the screws on the wall. Hang the Switch on the screws.
Note:
The Switch should be wall-mounted horizontally. The Switch's side panels with ventilation slots
should not be facing up or down as this position is less safe.
Installing Network Cables
1. Crossover or straight-through cable: All the ports on the switch support Auto-MDI/MDI-X
functionality. Both straight-through or crossover cables can be used as the media to connect the
switch with PCs as well as other devices like switches, hubs or router.
2. Category 3, 4, 5 or 5e, 6 UTP/STP cable: To make a valid connection and obtain the optimal
performance, an appropriate cable that corresponds to different transmitting/receiving speed is
required. To choose a suitable cable, please refer to the following table.
Media Speed Wiring
10/100/1000 Mbps

Chapter 2 Basic Web Management Information
2.1 System login
1. Start your web browser.
2. Type “http://”and the IP address of the switch (for example, the default management IP address
is 192.168.1.1) in the Location or Address field. Press [ENTER].
3. The login screen appears. The default username and password are “admin”, so you can click
OK and go to the web configuration screen directly.

Management
VLAN
This allows the entry of a VLAN from which a management station will be
allowed to manage the device using TCP/IP (in-band via web manager or
Telnet). Management stations that are on VLANs other than the one selected
here will not be able to manage the Switch. The default management VLAN is
VLAN 1.

The following table describes the labels in this screen.
LABEL DESCRIPTION
Port Select
Enabled
Select the port(s) from the list box that you will change the port settings for.
Select Enable from the drop-down box to enable a port. The factory
default for all ports is enabled. A port must be enabled for data
transmission to occur. Select Disable to not use a port.
Speed
Port speed capabilities:
Auto: Auto speed with all capabilities.
Auto-10M: Auto speed with 10M ability only.
Auto-100M: Auto speed with 100M ability only.
Auto-1000M: Auto speed with 1000M ability only.
Auto-10/100M: Auto speed with 10/100M ability.
10M: Force speed with 10M ability.
100M: Force speed with 100M ability.
1000M: Force speed with 1000M ability.
Selecting Auto (auto-negotiation) allows one port to negotiate with a peer
port automatically to obtain the connection speed and duplex mode that
both ends support. When auto-negotiation is turned on, a port on the
switch negotiates with the peer automatically to determine the connection
speed and duplex mode. If the peer port does not support auto-negotiation
or turns off this feature, the switch determines the connection speed by
detecting the signal on the cable and using half duplex mode. When the
switch’s auto-negotiation is
turned off, a port uses the pre-configured
speed and duplex mode when making a connection, thus requiring you to
make sure that the settings of the peer port are the same in order to
connect.
Duplex
Port duplex capabilities:
Auto: Auto duplex with all capabilities.
Half: Auto speed with 10/100M ability only.
Full: Auto speed with 10/100/1000M ability only.

Flow Control
Apply
Flow Control
Config
Flow Control
Status
A concentration of traffic on a port decreases port bandwidth and
overflows buffer memory causing packet discards and frame losses. Flow
Control is used to regulate transmission of signals to match the bandwidth
of the receiving port. The switch uses IEEE802.3x flow control in full
duplex mode and backpressure flow control in half duplex mode.
IEEE802.3x flow control is used in full duplex mode to send a pause signal
to the sending port, causing it to temporarily stop sending signals when the
receiving port memory buffers fill. Back Pressure flow control is typically
used in half duplex mode to send a "collision" signal to the sending port
(mimicking a state of packet collision) causing the sending port to
temporarily stop sending signals and resend later.
Select “Enabled” to enable it. Or select “Disabled” to disable it.
Click Apply to save your changes to the switch.
The Config column displays if Flow Control has been configured to be
turned On or Off for the port.
The column displays the port’s current Flow Control status.
3.3.2 Port Mirroring
The Mirror function copies all the packets that are transmitted by the source port to the destination
port. It allows administrators to analyze and monitor the traffic of the monitored ports.
The Mirror Configuration steps are as follows:
Click Switching > Mirror > Local Mirror Setting in the navigation panel to display the screen as
shown below.
