Chapter 2 Preparations before Instruction
2.1 Precautions
Please read the following precautions carefully before operation, to avoid damaging the
device or causing body injuries.
1). Please remove the power socket before cleaning the switch. Don’ wipe the switch with wet
cloth or wash the switch with liquid.
2). Don’t stock the device in damp environment or near water, to avoid water or moisture
penetrating into the inner device.
3). Don’t put the device on a unstable box or desk, the device will get damaged from falling.
4). Please keep good ventilation indoor, and make sure the heat dissipation function of switch
works well.
5). The switch only works normally in suitable voltage. Please check the working voltage first.
6). Please don’t open the switch enclosure randomly, especially when the switch is powered
on, there is risk of electric shock.

User’s Guide

7). Please wear anti-static wrist strap when change the interface board,to avoid the static
electricity damage the board.
2.2 Check Installation Environment
The switch is for indoor use only, please pay attention to the following problems when install
the switch in a cabinet or put the device directly on the desktop.
1) The air vents of switch must have enough space to dissipate the heat inside enclosure.
2) A good heat dissipation system in the cabinet or on the desktop.
3) The cabinet or desktop strong enough to support the weight of switch and installation
accessories.
4) Safe ground connection for the cabinet or desktop.
2.3 Installation Tools

2) Cross screw driver
3) Anti-static wrist strap
Chapter 3 Installation
3.1 Install the Switch
3.1.1 Install the switch on a 19 inch standard cabinet
1) First fix the provided two L-shaped brackets on the two sides of switch.
2) Fix the switch on the rack with screws(screws are not provided).
Picture 3.1.1 Cabinet Installation
3.1.2 Install the switch on the desktop
When there is no 19 inch standard cabinet, the switch is usually put on clean desktop. The
operation is easier, please follow the below instructions:
1) Keep the desktop stable and safely grounded.
2) Set aside 10cm space around switch for heat dissipation.

User’s Guide
Page 8 of 34
3) Don’t put any heavy device on the switch.

3.2.2 Connection of AC power cord
Step one: please connect one end of power cord to the power jack on the switch rear panel,
Connect the other end to the AC power socket.
Step two: check the power indicator(PWR) on the front panel, if the LED is on, connection is
Successful.
3.3 Test after Installation
Make sure the working voltage is the same with the rated voltage of switch.
Check the connection of grounded cord.
Check the connection of configuration cable and power input cord.

Switch adopt Web-based interface management, the default IP is 192.168.255.1. Please
make sure the IP address of PC is in the same network segment with that of switch,or the PC
can’t access to manage the switch. After the setting of IP address, please input
192.168.255.1 in the browser to access the configuration interface of switch.
The Web management interface consists of five parts, which are switch status, basic
configuration, advanced configuration, network security, system maintenance.
Picture 1.1.1 Login Page
Enter user password in the above login page, the default password is admin. The system only
support single user login, other logins will be refused until the user logs out.
If IP address conflict occurs, it suggests the latest user didn’t log out successfully. Please
reboot the device or try to log in again180s later.
It is advised to reset the IP address and password in first login, and make sure the switch is
not configured in the same network segment with DHCP server or Internet Gateway device.

The above IP address configuration page can be used to configure the IP address of
device management interface “Interface Vlan 1”. The default IP address, subnet mask
and gateway will be showed in the page. When revise the configuration, please press
“save”to confirm new configuration. Press “reset”to back to original configuration.
Above configuration need to be done under default “Static”state,if switch the IP address
mode to DHCP, IP address will be get dynamically. Please record the new IP address for
future login.
Notice: Don’t modify the subnet mask unless exceptional case, login problem will be caused by
improper modification.

System log configuration is checked in above page. Remote log server can be
configured, system log can be saved on the remote server as backup use. Enable or
disable the remote backup function in this page, “server IP address”need to be entered
manually.
3.4Port Setting
Picture 3.4.1 Port Setting
Port Status: The user can enable or disable a port in this page.Click “Enable” to open the port,
click “Disable” to close the port, the default setting is “Enable”.
Port Mode: 6 modes can be configured:Auto-negotiation,10 Half,10 Full,100 Half, 100 Full
and1000 Full. Default mode is Auto-negotiation, can be changed in pull-down list.
Flow Control: This function is defaulted closed, open it when needed.
Loop Detection:The function is defaulted closed, open it when needed.A port will be blocked
to cut the loop when loop is detected.( Notice: the port link indicator in front panel will be still
on when the port is blocked, for the physic connection is existed; while the link indicator on

the top of web management pages will be off.)
Chapter 4 Advanced Configuration
4.1 Port Mirror Configuration
Picture 4.1.1 Port Mirror Configuration
Users can do Port Mirror Configuration in above page. Port mirroring is used on a network
switch to send a copy of network packets or data traffic from some ports (or an entire VLAN)
to a network monitoring connection on specified switch port. The original port is called Source
Port, and the specified port is Mirroring Port. This is commonly used for network appliances
that require monitoring of network traffic without influencing the normal working of every port,
it’s a convenient online-monitoring function.
All ports have mirroring function, but only one port can be configured as Mirroring Port. In the
same system, there is only one mirroring port, while more than one Source Ports can be
existed. When a port is configured as mirroring port, its corresponding port can’t be
configured as source port.

User’s Guide

4.2 Port Aggregation
4.2.1 Static Aggregation
Picture 4.2.1 Static Aggregation
Switches support 8 aggregation groups, each group contains maximum 8 ports. The
members in the same aggregation group should have same configuration for port
forwarding rate mode and VLAN distribution.
If LACP function applied for some ports, then static aggregation can’t be configured.
Notice: Static aggregation can’t be configured when LACP function enabled.
4.2.2 LACP Setting
Picture 4.2.2 LACP Setting
When the LACP protocol is on, the aggregated devices interactively gather information
through LACP. According to the parameters and status of each device, automatically receive
and dispatch Data of matchable link aggregation. When the Aggregation is formed, switches
keep in an aggregation link status, switches automatically adjusts link aggregation or
dissolute when configuration changes.
If the port is configured as static aggregation, the dynamic LACP will be not available.
Notice: Static aggregation LACP function can’t be used together.
