Hardware Installation
Before installing the device, make sure you have all of the package contents available and a
PC with Microsoft Internet Explorer 6.0 or later, for using web-based system management
tools.
Wheninstalled outdoors, make sure the connectors on the panel are facing down
to prevent water intrusion.
Do not remove the water-proof casing, and avoid touching or moving the device
when the antennas are transmitting or receiving.
When installing the device, make sure to keep the radiating at a minimum
distance of 20 cm (7.9 inches) from all persons to minimize the potential for
human contact during normal operation.
Do not operate the device near unshielded blasting caps or in an otherwise
explosive environment unless the device has been modified for such use by
qualified personnel.
The device can be fixed to a pole or the wall using the supplied mounting plate. Make sure
the connectors on the bottom panel are facing down when installing to prevent water
intrusion.

Instead of screwing the screws in all the way, it is advised to leave a space of about
2mm to allow room for sliding the device between the wall and the screws.
3.2 Pole Mounting
You can mount the device to a pole using adjustable steel band straps included in the kit.
When installing the device to a pole:
Step 1: Attach the mounting plate to the back of the device using four screws. The plate can

Management
5.1 Network Connection
Before installing the gateway, you need to be able to access the gateway 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.
Please Follow the steps below to install and connect the gateway to PCs:
Step 1: Select a power source. The device is powered via the PoE (Power over Ethernet)
port, so there is no need for additional power cords..
Step 2: Connect a computer to the device. Use either a straight-through Ethernet cable or
cross-over cable to connect the ETH1 port of the gateway to a computer. Once the LED of
the LAN port lights up, which indicates the connection isestablished, the computer will initiate
a DHCP request to retrieve an IP address from the VPN gateway.
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 web page. 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.

Subnet Mask
The subnet mask of the LAN. The default value is 255.255.255.0
LLDP Protocol
LLDP is a vendor-neutral protocol used by network devices for
advertising their identity, capabilities, and neighbors on a LAN. You
can enable or disable LLDP protocol.
DHCP
DHCP is a network protocol designed to allow devices connected to a network to
communicate with each other using an IP address. The connection works in a
client-server model, in which DHCP clients request an IP address from a DHCP server.
The gateway comes with a built-in DHCP (Dynamic Host Control Protocol) server which
assigns an IP address to a computer (DHCP client) on the LAN automatically. The gateway
can also serve as a relay agent which Sunday will forward DHCP requests from DHCP clients
to a DHCP server on the Internet.
The IP allocation provides one-to-one mapping of MAC address to IP address. When a
computer with a MAC address requesting an IP address from the gateway, it will be assigned
with the IP address according to the mapping. You can choose one from the client list and
add it to the mapping list.
