System Requirements
Before starting, you must ensure the following:
●You already have a cable or DSL broadband connection to the Internet, with a suitable modem, and that this connection works properly. The modem must have an Ethernet port for connection to your Gateway.
●You have a computer that has an Ethernet connection available and is already correctly configured for communication with the Internet. Your computer must be able to connect to the Internet via the modem, and must have a Web browser installed.
●There are no other DHCP server devices on your local network that are responsible for allocating IP addresses to your computers and other network- connected devices. Your Gateway will now perform this function by default.
If one or more of these conditions are not met, refer to the comprehensive Gateway User Guide provided for further guidance.

When positioning your Gateway, ensure:
●It is out of direct sunlight and away from sources of heat.
●Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical noise such as radios, transmitters and broadband amplifiers.
●Water or moisture cannot enter the case of the unit.
●Air flow around the unit and through the vents in the side of the case is not restricted. We recommend you provide a minimum of 25mm (1in.) clearance.

1Alert LED orange
Indicates a number of different conditions, as described below.
Off - The Gateway is operating normally.
Flashing quickly (1/2 second on - 1/2 second off) - Indicates one of the following conditions:
•The Gateway has just been started up and is running a self-test routine, or
•The administrator has invoked the Reset to Factory Defaults command, or
•The system software is in the process of being upgraded
In each of these cases, wait until the Gateway has completed the current operation and the alert LED is Off.
Flashing slowly (2 seconds on - 2 seconds off) - The Gateway has completed the Reset to Factory Defaults process, and is waiting for you to reset the unit. To do this, remove power, wait 10 seconds and then re- apply power. The Gateway will then enter the start- up sequence and resume normal operation.
On for 2 seconds, and then off - The Gateway has detected and prevented a hacker from attacking your network from the Internet.
Continuously on - A fault has been detected with your Gateway during the start-up process. Refer to the main User Guide.
2Power LED green
Indicates that the Gateway is powered on.
3Four LAN Status LEDs
green (100Mbps link) / yellow (10Mbps link)
If the LED is on, the link between the port and the next piece of network equipment is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, or the connected device is switched off, or there is a problem with the connection (refer to the "Problem Solving" section).
4Cable/DSL Status LED
green (100Mbps link) / yellow (10Mbps link)
If the LED is on, the link between the Gateway and the cable or DSL modem is OK. If the LED is flashing, the link is OK and data is being transmitted or received. If the LED is off, nothing is connected, the modem is switched off or there is a problem (refer to the "Problem Solving" section).
5Power Adapter socket
Only use the power adapter that is supplied with this Gateway. Do not use any other adapter.
6Ethernet Cable/DSL port
Use the supplied patch cable to connect the Gateway to the 10/100 port on your cable or DSL modem. This port will automatically adjust for the correct speed, duplex and cable type. Which means you can connect to your Cable/DSL modem using either straight-through or crossover cables.
7Four 10/100 LAN ports
Use suitable cable with RJ-45 connectors. You can connect your Gateway to a computer, or to any other piece of equipment that has an Ethernet connection (for example, a hub or a switch). These ports will automatically adjust for the correct speed, duplex mode and cable type, which means that you can connect devices to your Gateway using either straight-through or crossover cables.
