LED Descriptions
The LEDs on the front panel provide users with switch status checking and
monitoring. There are three types of LEDs as follows:
•System LED indicates if the switch is powered up correctly or not, or,
indicates if there is a system alarm triggered for troubleshooting.
•Mode LEDs indicates the mode of all RJ45/SFP ports on the switch.
Users can press the Mode button sequentially to switch among the two
different modes (Link/Activity/Speed mode and PoE mode).
•Port Status LEDs indicates the current status of each RJ45/SFP port.
Users can check these LEDs to understand the port status in different
modes, after changing the mode by pressing Mode button.
The following table details the functions and descriptions of various LED
indicators. Table 1: System LED

Mode/Reset Button
By pressing the Mode/Reset Button for certain period of time, users can
perform the following tasks.
•Change Port Status LED Mode to read the port status correctly in the
two different modes (Link/Act/Speed mode or PoE mode).
•Reset the Switch to reboot and get the switch back to the previous
configuration settings saved.
•Restore the Switch to Factory Defaults to restore the original
factory default settings back to the switch.
Note: According to the table below, users can easily judge which task is
being performed by reading the LED behaviors while pressing the
Mode/Reset button. Once the LED behaviors are correctly
displayed, users may just release the button.

Chapter 2 Installing the Switch
Package Contents
•The Switch
•AC Power cord
•Four adhesive rubber feet
•Installation Guide
•Mounting kit
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 in a 19-inch Rack
Step 1: Attach the mounting brackets to both sides of the chassis. Insert screws
and tighten then with a screwdriver to secure the brackets.
Figure 3: Attaching Brackets to the Switch
Step 2: Place the switch on a rack shelf in the rack. Push it in until the oval holes
in the brackets align with the mounting holes in the rack posts.
Step 3: Attach the brackets to the posts. Insert screws and tighten them.
Figure 4: Attaching Brackets to the Rack Post

Mounting the Switch on Desk or Shelf
Step 1: Verify that the workbench is sturdy and reliably grounded.
Step 2: 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.
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.

Chapter 3 Initial Configuration of
Switch
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,
192.168.0.250), then you can access the Web interface of the switch using
the switch’s default IP address as shown below.
Note: The factory default IP address of the switch is 192.168.0.1
The factory default Subnet Mask of switch is 255.255.255.0
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:

10
Step 1:Type “network and sharing“ into the Search box in the Start
Menu
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 window
highlight 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 between 192.168.1.2 and 192.168.1.254), 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.
If your PC is configured correctly, you will see the login page of the
switch as shown by Figure 9 below.

11
Figure 9: 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.
- Clean browser 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 is admin
The factory default Password of the switch is admin

state has been
detected by the
switch.
Check the system log within the switch
from WEB UI to understand the abnormal
state (e.g. exceeding operating
temperature range) and take
corresponding actions to resolve.
