CHAPTER 1
Intro duc ing the PLA
1.1 O ve rvie w
This chapter introduces the main applications and features of your Zyxel G.hn Powerline adapter, which
is called “PLA” in this guide.
The PLA plugs into an ordinary power outlet to easily extend a cable or DSL broadband connection or
existing Ethernet (LAN) network to any other electrical outlet in any room of a house, all without the
need for any new cabling. The AC power pass-through feature allows you to unplug electrical device
from a power socket, plug the PLA into the socket and then plug the electrical device back into the
PLA. The power plug varies depending on your region.
In the following diagram, the first PLA (PLA1) connects to an Internet gateway such as a modem and
plugs into an ordinary power outlet. The second PLA (PLA2) plugs into another power outlet and
connects to a computer. PLA1 and PLA2 communicates through ordinary power lines.
Fig ure 1 PLA Application
Refer to your Quick Start Guide for hardware connection information.
In this User’s Guide the electrical wiring network is referred to as the “G.hn Network”.

1.1.1 G .hn Sta nda rd
G.hn is a specification for home networking devices that operates over power lines. G.hn specifies the
point-to-point security inside a domain, which means that each pair of transmitter and receiver uses a
unique encryption key which is not shared by other devices in the same domain. Devices can securely
communicate with each other at high data transfer rates.
The PLA uses 128-bit Advanced Encryption Standard (AES) to ensure safe transfer of information.
1.2 LEDs
The following section describes the lights (LEDs) on the PLA.
The following figure is the front panel of the PLA. Use the lights to determine if the PLA is behaving
normally or if there are some problems on your G.hn Network.
Fig ure 2 PLA Lights
The following table describes the behavior of the lights on the PLA.

1.3 Sta ndb y Mo de
You can set your PLA to save on power when there is no Ethernet connection or activity. Use the Web
Configurator’s Ethe rne t screen to set the period of time when the PLA will go into standby mode. Refer
to Section 3.5 on page 22 for details on this feature.
The PLA’s power LED blinks signaling that it is going into standby mode. The Ethernet LED, Encrypted
Pairing LED, and Powerline LED are turned off in standby mode.
Note: While in standby mode, you cannot use the RESETand ENC RYPT buttons. To enable the
RESETand ENC RYPTbuttons again, you have to connect the PLA’s Ethernet cable to a
computer/notebook or modem/router first. The PLA wakes up from standby mode and
you can start using the RESETand ENC RYPT buttons.
1.4 Wa ys to Ma na g e the PLA
Use the ENC RYPTbutton to add PLAs to your G.hn Network. See Chapter 2 on page 12 for instructions on
using the ENCRYPT feature.
Use the Web Configurator to manage the PLA. See Chapter 3 on page 17 for instructions on using the
Web Configurator.
1.5 Expa nd Yo ur Ne two rk with the PLA
Your network can be further expanded by plugging additional PLAs into other outlets in your home and
connecting other computers or network devices (for example, a Smart TV) to them.

1.6 Se c urity
Since your G.hn Network may extend outside your premises, it is important to set up security on your PLA.
1.6.1 Do m a in Na m e
You can use the domain name to identify your PLA in the G.hn Network.
1.6.2 Se tting Up Enc rypte d Pa iring
The ENCRYPT feature automatically sets up encrypted pairing on your G.hn Network using the ENC RYPT
button (see Section 2.1 on page 12 for more information). It involves authenticating the identity of the
two PLAs to be paired and encrypting the link.
Alternatively, use the Web Configurator to set up encrypted pairing on the PLA. Although the PLA is a
“plug-and-play” network expanding solution there are several reasons for enabling security on the G.hn
Network in your home.
1It is easy and only requires you to change a network name.
Table 3 Domain Name Summary
IDENTITY DESC RIPTIO N
Domain Name Your PLA follow the G.hn standard and is shipped with the same domain name “G.hn
Network”. Change the domain name through the Web Configurator or RESETbutton to
create a private network. See Section 3.4 on page 20.

Chapter 1 Introducing the PLA
PLA6457 User’s Guide

2It is a good idea to ensure privacy of your communication. When you use the PLA and other PLAs, the
electrical wiring in your home becomes an extension of your Ethernet network. Your network traffic flows
freely within the electrical circuit of your home and is bounded in most cases by a power meter.
Without encrypted pairing (security) your information is accessible to anyone using a PLA on the same
electrical circuit. In some cases, a circuit can be shared by more than one household.
To prevent compromising your network security, you can create a private network. A private network
uses a Do m a in Na m e to make sure that only permitted PLAs can communicate in your network. See
Section 3.4 on page 20 for information on setting up a private network.
3You may need to change the Do m a in Na m e to create multiple G.hn Network. See the next section for
more information on how to set up a multiple network.
1.7 Multiple Ne two rks
Multiple G.hn Networks can coexist on a single electrical circuit. You might want to implement multiple
G.hn Networks in a small office environment where you have two independent Ethernet networks.
1Connect one PLA to a router or switch on the first Ethernet network and assign a Dom a in Na m e (for
example “Tom’s Network”) to this PLA (see Section 3.3 on page 19 for more information). Add additional
PLAs to your network by plugging them into your Powerline outlets and assigning them “Tom’s Network”.
This completes the configuration of your first G.hn Network.
2Connect another PLA to a router or switch on the second Ethernet network and assign a different
Do ma in Na m e (for example “Alice’s Network”) to this PLA. Again, add additional PLAs and assign them
“Alice’s Network”.
You now have two private networks on your Powerline circuit. Information is not shared between the
two networks as only PLAs with the same criteria for this Do m a in Na m e can communicate with each
other.

RESETa nd ENC RYPTButto ns
2.1 ENC RYPTButto n
The ENC RYPTbutton allows you to set up a secure Powerline connection with other G.hn compliant PLAs
which also support the ENCRYPT feature. No other Powerline setting changes are required to connect.
The following table summarizes the actions that occur when the ENC RYPTbutton is pressed for specific
lengths of time.
Note: The domain name is unknown when you use the ENC RYPT button.
2.2 Adding De vic e s to a G .hn Ne two rk
You can connect a number of PLAs on a G.hn Network, but you can use the ENC RYPT button on only
two PLAs at a time.
Place a PLA close to another PLA so you have time to set up each one. After you set up the first PLA, you
have 120 seconds to set up the second PLA.
Note: Your PLA must be connected to a networking equipment for the ENC RYPT button to
work. Refer to Section 1.3 on page 9 for more details.
Follow the steps below to set up your G.hn Network:
1Press the ENC RYPTbutton at the side of your PLA for 2 to 5 seconds. The encrypted pairing ( ) light will
blink as the PLA tries to set up a connection with a new random domain name.

should be on while the devices are connecting. Wait for about 2 minutes while your
PLAs connect.
If the encrypted pairing ( ) light does not blink when you press ENCRYPT, you have probably
pressed the ENCRYPT button for too long. Try pressing the ENCRYPT button again for 2 to 5
seconds.
If the Powerline ( ) lights on both PLAs do not light up, the PLAs are not connected. Repeat step
1 in this section. If that does not work, see Troubleshooting in Section 5.4 on page 36 for
suggestions.
2To add more PLAs to your network, use any PLA (A or B) you have connected to set up a connection
with the PLAs you want to connect (C and D).
3Press the ENC RYPTbutton on both PLAs (Aand C, or Band C) for 2 to 5 seconds to add PLA C. This must
be done within 2 minutes (120 seconds) of pressing the ENC RYPT button on the PLA.
4Press the ENC RYPTbutton on both PLAs (Aand D, Band D, or Cand D) for 2 to 5 seconds to add PLA D.

3.1 O ve rvie w
This chapter shows you how to use the Web Configurator to secure and manage on your G.hn network.
The Web Configurator is an HTML-based management interface that allows easy PLA setup and
management through Internet browser. Use a browser that supports HTML5, such as:
• Microsoft Edge
• Internet Explorer 11 or later
• Google Chrome 34.0.1847.131 or later
• Mozilla Firefox 29.0.1 or later
• Opera 21.0 or later
• Safari 5.1.7 or later
The recommended minimum screen resolution is 1024 by 768 pixels. In order to use the Web Configurator
you need to allow:
• Web browser pop-up windows from your device. Web pop-up blocking is enabled by default in some
browsers.
• JavaScript (enabled by default).
• Java permissions (enabled by default).
The PLA is designed as a plug-and-play network expanding solution. This means that once you
complete your hardware connections, the PLAs in your network (without additional configuration) are
able to communicate with each other by sending and receiving information over your home’s
electrical wiring (A).
Fig ure 7 Example Network Setup
All G.hn compliant PLAs within range can join your network. The range varies depending on the quality
of your home’s wiring.

See Section 3.1.1 on page 18 for more information on enhancing your G.hn network security.
3.1.1 G .hn Ne two rk Se c urity
When the PLAs communicate with each other, they use encryption to protect the information that is
sent in the G.hn network. Encryption is like a secret code. If you do not know the secret code, you
cannot understand the message. The G.hn standard uses 128-bit AES (Advanced Encryption Standard)
to safely transmit data between PLAs.
For the PLAs to communicate with each other they all need to use the same network name (or Do m a in
Na m e ). This network name allows the PLAs to understand the encrypted information sent in the G.hn
network.
By default the PLAs are all configured with the network name G.hn, this allows you to simply plug the
devices in and not worry about setting up security. If you want to enhance the security on your G.hn
network, you can change the network name on the PLAs you want to allow to communicate in your
G.hn network.
3.2 Syste m Lo g in
1Make sure your PLA hardware is properly connected to a router with DHCP server (refer to the Quick
Start Guide). Note down the DHCP-assigned IP address for your PLA.
2Start your web browser.
3The PLA is a DHCP client by default. Type “http://DHCP-assigned IP address” in the Lo c a tio n or Addre ss

MAC address This field displays the MAC address of your PLA. The MAC address of your PLA can be found by
looking at the label on your device. It consists of six pairs of hexadecimal characters
(hexadecimal characters are “0 – 9” and “a – f”). In the case of the PLA, this label is on the back
of the device.
Device ID Every PLA acts as the DO MA IN_ MA STER by default before connecting to another PLA. The
default De vic e ID is 1.
After you press the ENC RYPT button to connect your PLA to another PLA, the two PLAs will
determine which one acts as the DO MA IN_MA STER. This field displays 1when your PLA is the
DO MA IN_MA STER. It displays 2when your PLA is the END_PO INT(see the Fo rc e no de Type field in
this table for more information).
Note: When none of the PLA works as the DO MA IN_MA STER in the network, you can
manually configure your PLA as the END_PO INTby selecting END_PO INT in the
Fo rc e no de Type field. The De vic e ID will be set to 0.

3.4 IP Se tting s
Use the IP screen to enable DHCP, or manually assign an IPv4 or IPv6 address, subnet mask, default
gateway, and DNS server to the PLA.
Domain Name The default domain name of the PLA is “G.hn Network”. The PLAs use the same domain name to
recognize and communicate with each other over the powerline network. If you change the
domain name of one device on the network, it will no longer be recognized as part of that
network.
If you change the domain name, make sure you change the domain name for all of the PLAs
that you want to be part of your powerline network.
The domain name can be from 8 to 64 characters in length, using “A”–”Z”, “a”–”z”, “0”–”9”;
spaces are not allowed.
Force node Type This field forces the PLA to have a particular role (END_PO INTor DO MA IN_MASTER).
• Select DO MA IN_ MA STER if your PLA connects to a router or AP.
• Select END_PO INTif your PLA connects to the end device (for example, computer).
• It is recommended to select the default setting A UTO MA TIC for automatic role detection of
the PLA.
Node type Shows the current role of the device based on your selection in the previous field.
Note: Node type change can take some time, click O k after making any changes in
the Fo rc e no d e Typ e field. You may need to refresh your webpage.
G.hn profile This field selects the G.hn profile of all PLAs to apply in the G.hn network (PLC 100 MHz MIMO
Bo o st, PLC 100 MHz Bo o st).
• Select PLC 100 MHz MIMO Bo o st (multiple input multiple output) when the PLA connects to a
3-prong electrical socket in your home. Multiple electrical paths between PLAs in the same
G.hn network are available and sending and receiving of data is through all 3 wires (power,
neutral, and ground).
• Select PLC 10 0 MHz Bo o st when the PLA connects to a 2-wire electrical socket. A single
electrical path between PLAs in the same G.hn network is available and sending and
receiving of data is through the 2 wires (power and neutral).
