Management
5.1 Network Connection
Before installing the device, you need to be able to access the device via a computer
equipped with an Ethernet card or wireless LAN interface. To simplify the connection, it is
recommended to use an Ethernet card to connect to a LAN.
Step 1: Select power source. The device can be powered by +12~48V DC power input.
Step 2: Connect a computer to the device. Use either a straight-through Ethernet cable or
cross-over cable to connect the device to a computer. Once the LED of the LAN port lights up,
which indicates the connection is established, the computer will initiate a DHCP request to
retrieve an IP address from the device.
Step 3: Configure the device on a web-based management utility. Open a web browser on
your computer and type http://192.168.10.1 (default gateway IP of the device) in the address
box to access the webpage. A login window will pop up where you can enter the default login
name admin and password admin. For security reasons, we strongly recommend you to
change the password. Click on System Tools > Login Setting after logging in to change the
password.
