•Installation Guide
•Mounting kit
Mounting the Switch on a DIN Rail
Step 1: Attach the DIN Rail mounting kit to rear panel of the chassis.
Insert screws and tighten then with a screwdriver to secure the
kit.
Figure 3: Attaching DIN Rail Kit to the Switch
Step 2: Insert the upper lip of the DIN rail into the DIN-rail mounting
kit. And press the switch towards the DIN rail until it snaps into
place.

7
Figure 4: Insert switch to the DIN Rail
Step 3: Make sure that the switch is attached securely to DIN Rail.
Figure 5: The switch is attached to DIN Rail
Mounting the Switch on Wall (Optional)
Step 1: Attach the wall mounting plates to rear panel of the chassis.
Insert screws and tighten then with a screwdriver to secure the
plates.

8
Figure 6: Attaching Wall Mounting Plates to the Switch
Figure 7: The Dimension of Wall Mounting Plates
Step 2: Install user-supplied screws on the appropriate location on the
wall.
Step 3: Make sure that the switch is attached securely to wall.
Connecting the DC Power Cord
Step 1: Insert the negative/positive DC wires into the V-/V+ terminals,
respectively.

9
Step 2: To keep the DC wires from pulling loose, use a small flat-blade
screwdriver to tighten the wire-clamp screws on the front of the
terminal block connector.
Step 3: Insert the terminal block connector prongs into the terminal
block receptor.
Step 4: Check the SYS LED. If it is ON, the power connection is correct.

Connecting the DI/DO Relay Wires
Figure 9: Connecting DI/DO Relay Wires

10
STEP 1: Insert the negative (ground)/positive DI/DO Relay wires into the
+/- terminals, respectively.
STEP 2: To keep the DI/DO Relay wires from pulling loose, use a small
flat-blade screwdriver to tighten the wire-clamp screws on the
front of the terminal block connector.
STEP 3: Insert the terminal block connector prongs into the terminal
block receptor.
Note:
Digital output (relay): 24VDC/1A
Digital input: level 0(Low) -> 0V to 6V, level 1 (High) -> 10V to 24V
FAULT:
The two contacts of the terminal block connector are used to detect
user-configured events. The two wires attached to the fault contacts form
an open circuit when a user-configured event is triggered. If a user-
configured event does not occur, the fault circuit remains closed.
Installing SFP Modules
You can install or remove a mini-GBIC SFP module from a SFP port
without having to power off the switch.
Step 1: Insert the module into the SFP port.
Step 2: Press firmly to ensure that the module seats into the connector.

Note:
The SFP ports should use UL Listed Optional Transceiver product, Rated
3.3Vdc, Laser Class 1.

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, 192.168.1.250), 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 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:
Step 1: Type “network and sharing“into the Search box in the Start
Menu

13
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.

14
If your PC is configured correctly, you will see the login page of the switch
as shown by Figure 9 below.
Figure 11: 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.
