Chapter 2 Installation
2.1 Connecting Cables
Place HG520 in a safe and accessible location where you can
easily view the LED indicators on the front panel of the device.
HG520 should be connected to a phone port, a power socket,
and a computer or the network before it functions.
Caution:
Ifyouneedtoinstall a telephone between HG520andthewallsocket,makesure you
install a splitter first to prevent loss in voice quality.
You are now ready to connect HG520. Follow these steps:
I. Disconnect the power – Make sure you turn off the power for
the computer and HG520.
II. Connect the ADSL cable
Use a telephone cable to connect the DSL interface of HG520 to
either of the following interfaces:

Huawei Technologies Proprietary
12
zWall socket: Plug one end of the twisted-pair cable
(standard phone line) into the ADSL port on the rear panel of
HG520 and insert the other end into the wall socket.
zExternal splitter: Or you can insert one end of the
twisted-pair ADSL cable into the modem connector on the
external splitter.
zInsert the other end into the ADSL connector on the back
panel of HG520.
zAfter installed, you can connect telephone to the phone
connector on the external splitter.
III. Connect HG520 to your computer – Use an Ethernet cable
provided to connect HG520 and your computer or notebook PC
through the 10/100Base-TX Ethernet ports.
IV. Connect the power supply and start up HG520– Use the
power adapter supplied and switch the power switch to the ON
position. The Power LED indicator lights up and remain lit. Check and
make sure the electronic current and voltage meet the requirement of
the supplied power adapter. Check and make sure that the LAN: LINK
and ADSL: LINK LED indicators light up in green. This indicates a
successful connection between the ISP and the user’s PC.
Note:
zPlease note that the cable supplied is the straight-through cable. Be sure that the
cable connected between LAN and HG520 does not exceed 100 meters.
zUse crossover cable to connect HG520 and the uplink port of a switch or hub.

Chapter 3 Configuration Preparation
The default value of HG520 meets the need of most of the
network environment. Beginners and the users with simple network
environment are able to plug and play with no need to configure
HG520.
However, if the network location of HG520 is within the network
scope, and special requirements or modifications were done to the
cooper wire loop quality/quantity, network protocol, network topology
structures and other aspects. For instance, if you need to set a special
value for the VPI/VCI, it is highly recommended that you configure the
related settings for HG520 to adapt to the new network environment.
3.1 Build up a Configuration Environment
Before the configuration, ensure that you have made the
following preparations:
4) Connect HG520 and your computer with the straight-through
cable as shown in Figure 3-1.
5) Power on HG520 and start up the computer.
6) Configure the computer to obtain IP address automatically.
Or you can configure the computer IP address to be in the
same network segment as HG520. Thedefault IP address of
HG520 is192.168.1.1.
