Package Contents
The Switch
AC Power cord (Option)
Four adhesive rubber feet
Installation Guide
Note:
The switch is an indoor device. If it is to be used with outdoor devices
such as outdoor IP cameras or outdoor WiFi APs, then users are strongly
suggested to install a surge protector or surge suppressor in order to
protect the switch.
Mounting the Switch on Wall
Step 1:stall user-supplied screws on the appropriate location on the all,
and be aware of the dimensional limitation of the screws.
Figure 3: Installscrews to the wall

Step 2:make sure that the switch is attached securely to wall.
Figure 4:Attaching switch to the wall
Mounting the Switch on Desk or Shelf
Step1: Verify that the workbench is sturdy and reliably grounded.
Step2:Attach the four adhesive rubber feet to the bottom of the switch.
Figure 5:Attaching the Rubber Feet
Connecting the AC Power Cord
Step 1:Connect the AC power cord to the AC power receptacle of
switch.

7
Step 2:Connect the other end of the AC power cord to the AC power
outlet.
Step 3:Check the SYS LED. If it is ON, the power connection is correct.
Figure 6:Connecting AC power cord
Installing SFP Modules
You can install or remove a mini-GBIC SFP module from a SFP port
without having to power off the switch.
Step1:Insert the module into the SFP port.
Step2:Press firmly to ensure that the module seats into the connector.

Chapter 3 Initial ConfigurationofSwitch
Initial Switch Configuration Using Web Browsers
After powering up the switch for the first time, you can perform the initial
switch configuration using a web browser. For managing other switch
features, please refer to the Web interface user guide for details.
To begin with the initial configuration stage, you need to reconfigure your
PC’s IP address and subnet mask so as to make sure the PC can
communicate with the switch. After changing PC’s IP address (for example,
192.168.1.250), then you can access the Web interface of the switch using
the switch’s default IP address as shown below.
The initial switch configuration procedure is as follows:
Note:
The factory default IP address of the switch is 192.168.1.1
The factory default Subnet Mask of switch is255.255.255.0
Initial Switch Configuration Procedure
The initial switch configuration procedure is as follows:
1. Power up the PC that you will use for the initial configuration. Please
make sure the PC has the Ethernet RJ45 connector to be connected to
the switch via standard Ethernet LAN cable.
2. Reconfigure the PC’s IP address and Subnet Mask as below, so that it
can communicate with the switch.The method to change the PC’s IP
address, for example, for a PC running Windows® 7/8.x/10, is as
follows:
Step 1:Type “network and sharing“into the Search box in the Start
Menu

10
Step 2: Select Network and Sharing Center
Step 3: Click on Change adapter settings on the left of PC screen
Note:
Users can also skip step 1 to 3, by pressing WinKey+Rand
type ”ncpa.cpl”command to get to step 4 directly.
Step 4:Right-click on your local adapter and select Properties
Step 5:In the Local Area Connection Properties
windowhighlight Internet Protocol Version 4 (TCP/IPv4)
then click the Properties button.
Note:
Be sure to record all your PC’s current IP settings to be able to restore
them later.
Step 6: Select the radio button Use the following IP address and
enter in the IP for the PC (e.g. any IP address not in use, and in
between192.168.1.2 and192.168.1.254), Subnet mask (e.g.
255.255.255.0), and Default gateway that corresponds with
your network setup. Then enter your Preferred and Alternate
DNS server addresses.
Step 7: Click OK to change the PC’s IP address.
3. Power up the switch to be initially configured, and wait until it has
finished its start-up processes.
4. Connect the PC to any port on the switch using a standard
Ethernet cable, and check the port LED on the switch to make sure
the link status of the PC’s is OK.
5. Run your Web browser on the PC, enter the factory default IP
address,so as to access the switch’s Web interface.

11
If your PC is configured correctly, you will see the login page of the switch
as shown by Figure 9 below.
Figure 8:Web Interface login page
If you do not see the above login page, please perform the following
steps:
- Refresh the web page.
- Check to see if there is an IP conflict issue.
- Cleanbrowser cookies and temporary internet files.
- Check your PC settings again and repeat step 2.
6. Enter the factory default username and password in login page.
Click “Login” to log into the switch.
Note:
The factory default Username of the switch isadmin.
There is no factory default Password of the switch.
