SAFETY INFORMATION
SAFETY INFORMATION
CAUTION: Circuit devices are sensitive to static electricity, which can damage their delicate electronics. Dry weather conditions
or walking across a carpeted floor may cause you to acquire a static electrical charge.
To protect your device, always:
Touch the metal chassis of your computer to ground the static electrical charge before you pick up the circuit device.
Pick up the device by holding it on the left and right edges only.
If you need to connect this device to an outdoor device, add an arrester on the cable between the outdoor device and this device.
NOTE: The switch is indoor device; if it will be used in an outdoor environment or connects with an outdoor device, you must use
a lightning arrester to protect the switch.
WARNING:
Self-demolition on the product is strictly prohibited. Damage caused by self-demolition will be charged repairing fees.
Do not place product at outdoor or sandstorm..
Before installation, make sure the input power supply and product specifications are compatible with each other.
To reduce the risk of electric shock, disconnect all AC or DC power cord and RPS cables to completely remove power from the unit.
Before importing/exporting a configuration, make sure the firmware version is always the same.
After a firmware upgrade, the switch will replace the configuration automatically with the latest firmware version.
WARNING: EYE HAZARD! The SFP modules are Class 1 laser devices. Do not look direcly at the beam coming from the transmit
port.

CHAPTER 4: CONFIGURATION
4.1 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, 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 the 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.
NOTE:
The factory default IP address of the switch is 192.168.1.1
The factory default Subnet Mask of switch is 255.255.255.0
4.2 INITIAL SWITCH CONFIGURATION PROCEDURE
The initial switch configuration procedure is as follows:
STEP 1. Power up the PC that you will use for the initial configuration. Make sure the PC has an Ethernet RJ-45 connector to be
connected to the switch via standard Ethernet LAN cable.
STEP 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 2A: Type “network and sharing“ into the Search box in the Start Menu.
STEP 2B: Select Network and Sharing Center.
STEP 2C: Click on Change adapter settings on the left of the PC screen.
NOTE: Users can also skip step 1 to 3, by pressing WinKey+R and type ”ncpa.cpl” command to get to step 4 directly.
STEP 2D: Right-click on your local adapter and select Properties.
STEP 2E: In the Local Area Connection Properties window, highlight Internet Protocol Version 4 (TCP/IPv4) then click the
Properties button.
NOTE: Record all your PC’s current IP settings to be able to restore them later.
STEP 2F: 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 2G: Click OK to change the PC’s IP address.
STEP 3: Power up the switch to be initially configured, and wait until it has finished its start-up processes.
STEP 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 is OK.
STEP 5. Run your Web browser on the PC, enter the factory default IP address to access the switch’s Web interface.
If your PC is configured correctly, you will see the login page of the switch as shown in the following figure.

The following table provides information for users to easily troubleshoot problems by taking actions based on the suggested
solutions.
TABLE 5-1. TROUBLESHOOTING
SYMPTOM POSSIBLE CAUSE SUGGESTED SOLUTIONS
System LED is OFF The switch is not receiving
power
1. Check if correct power cord is connected firmly to the switch and to the AC outlet
socket.
2. Perform power cycling the switch by unplugging and plugging the power cord
back into the switch.
3. If the LED is still off, try to plug the power cord into different AC outlet socket
to make sure the correct AC source is supplied.
Port Status LED is OFF The port is not connected
or the port is not working
1. Check if the cable connector plug is firmly inserted and locked into the port
at both the switch and the connected device.
2. Make sure the connected device is up and running correctly.
3. If the symptom still exists, try a different cable or a different port, to identify
if it is related to the cable or specific port.
4. Check if the port is disabled in the configuration settings via the web user
interface.
