CHAPTER 1
Introducing the PLA
1.1 Overview
This chapter introduces the main applications and features of your ZyXEL HomePlug AV compliant
powerline adapter, which is called “PLA” in this guide. The following generic icon is used to
represent all PLA models.
In this User’s Guide the electrical wiring network is referred to as the “powerline network”. The
HomePlug AV standard specifies how network devices communicate using standard electrical
wiring.
This User’s Guide covers the following models:

Note: In this guide RESET/ENCRYPT refers to the ENCRYPT button in PLAs that have
separate RESET and ENCRYPT buttons.
You can directly plug an electrical device (such as a router or computer) into PLAs with an AC power
pass-through socket to supply power to the device.
There are two types of hardware for each of the PLA4101 and PLA4201 v2 models:
• One has an Ethernet port on the top and a power plug at the bottom of the rear panel.
• One has an Ethernet port on the bottom and a power plug at the top of the rear panel.
The power plug varies depending on your region.
1.2 LEDs
The following sections describes the lights 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 powerline network.
Figure 1 PLA Lights
The following table describes the behavior of the lights on the PLA.

1.3 Standby Mode (Power Saving Mode)
Your PLA is a certified green product. It goes into standby mode when there is no Ethernet
connection.
When you plug the PLA into an electric socket, it waits for an Ethernet connection. When no
connection is detected after three minutes, the Power LED blinks indicating that it is going into
standby mode.
The same process occurs when you disconnect the PLA from a previously working Ethernet
connection. Three minutes after disconnecting the Ethernet cable, the PLA’s power LED blinks
signalling that it is going into standby mode.
The Ethernet and HomePlug LEDs are turned off in standby mode.
While in standby mode, you cannot use the RESET/ENCRYPT button. To enable the RESET/
ENCRYPT button 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 RESET/
ENCRYPT button.
1.4 Ways to Manage the PLA
Use the RESET/ENCRYPT button to add powerline devices to your powerline network if they have
this button. See Chapter 2 on page 12 for instructions on using the ENCRYPT feature.
Use the ZyXEL PLA Series Configuration utility (or utility, for short) to manage the PLA. See
Chapter 3 on page 19 for instructions on installing the utility.
1.5 Expand Your Network with the PLA
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. 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.

Chapter 1 Introducing the PLA
PLA Series User’s Guide
10
Figure 2 Expand Your Network with the PLA
Connect your PLA to an Internet gateway such as a modem and plug it into an ordinary power
outlet in your home. Plug a second PLA into another power outlet and connect a computer to the
PLA for Internet access. 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
printer) to them.
Refer to your Quick Start Guide for hardware connection information.
1.6 Security
Since your powerline network may extend outside your premises, it is important to set up security
on your PLA.
1.6.1 Passwords
You use two types of passwords in the HomePlug AV powerline network. The following table
describes the differences between the passwords.
PLA
PLA
Table 5 Password Summary
PASSWORD DESCRIPTION
Network Name All powerline adapters that follow the HomePlug AV standard are shipped with the
same powerline network name “HomePlugAV”. Change the network name via the
ZyXEL PLA Series Configuration utility or RESET/ENCRYPT button to create a
private network. See Section 4.4 on page 32.
DAK (Data Access Key)
Password
In order to manage the powerline adapters on your powerline network you must
enter the adapters’ DAK password in the ZyXEL PLA Series Configuration utility.
This password is printed on the powerline adapter itself.
You don’t need to add the password for the powerline adapter directly connected to
the computer running the configuration utility (local powerline adapter), you only
have to add the remote powerline adapters’ passwords (those on your circuit, but
not directly connected to your computer).

Chapter 1 Introducing the PLA
PLA Series User’s Guide
11
1.6.2 Setting Up Security
The ENCRYPT feature automatically sets up security on your powerline network. Use this feature if
your powerline devices have the RESET/ENCRYPT button.
Alternatively, use the ZyXEL PLA Series Configuration utility to set up security on the PLA.
Although the PLA is a “plug-and-play” network expanding solution there are several reasons for
enabling security on the powerline network in your home.
1It’s easy and only requires you to change a network name.
2It’s a good idea to ensure privacy of your communication. When you use the PLA and other
powerline adapters, 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 security (encryption) your information is accessible to anyone using a powerline adapter 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 secret password (Network Name) to make sure that only permitted powerline
adapters can communicate in your network. See Section 4.4 on page 32 for information on setting
up a private network.
3You may need to change the Network Name to create multiple powerline networks. See the next
section for more information on how to set up a multiple network.
1.7 Multiple Networks
Multiple powerline networks can coexist on a single powerline circuit. You might want to implement
multiple powerline networks in a small office environment where you have two separate Ethernet
networks.
1Connect one powerline adapter to a router or switch on the first Ethernet network and assign a
Network Name (for example “Password1”) to this powerline adapter. Add additional powerline
adapters to your network by plugging them into your powerline outlets and assigning them
“Password1”. This completes the configuration of your first powerline network.
2Connect another powerline adapter to a router or switch on the second Ethernet network and
assign a different Network Name (for example “Password2”) to this powerline adapter. Again, add
additional powerline adapters and assign them “Password2”.
You now have two private networks on your powerline circuit. Information is not shared between
the two networks as only powerline adapters with the same Network Name can communicate with
each other.

CHAPTER 2
The RESET/ENCRYPT Button
Use the RESET/ENCRYPT button to automatically set up a secure powerline connection between
your powerline devices.
Note: In this guide RESET/ENCRYPT refers to the ENCRYPT button in PLAs that have
separate RESET and ENCRYPT buttons.
2.1 RESET/ENCRYPT Button Overview
The RESET/ENCRYPT button allows you to set up a secure powerline connection with other
HomePlug AV compliant powerline devices which also support the ENCRYPT feature. No other
powerline setting changes are required to connect.
You can use the RESET/ENCRYPT button to:
• set up a new powerline network.
• separate an existing powerline network into multiple networks.
• reset the PLA to the factory defaults.
2.2 Adding Devices to a Powerline Network
You can connect a number of PLAs on a powerline network, but you can use the RESET/ENCRYPT
button on only two PLAs at a time.
Place a powerline device close to another powerline device so you have time to set up each one.
After you set up the first powerline device, you have 120 seconds to set up the second powerline
device.
Note: Your PLA must be connected to a networking equipment for the RESET/ENCRYPT
button to work. Refer to Section 1.3 on page 9 for more details.
Follow the steps below to set up your HomePlug AV Network:
1Press the RESET/ENCRYPT button at the side of your powerline device for 0.5 to 3 seconds. The
power ( ) light will blink as the powerline device tries to set up a connection with a new random
network name.

Chapter 2 The RESET/ENCRYPT Button
PLA Series User’s Guide
13
Figure 3 ENCRYPT Connection Procedure
Note: The RESET/ENCRYPT button’s location varies for each Powerline model.
Note: Check the lights on the two powerline devices. The power ( ) and HomePlug ( )
lights should be on while the devices are connecting. Wait for about two minutes
while your powerline devices connect.
If the power ( ) light does not blink when you press RESET/ENCRYPT, you have probably
pressed the RESET/ENCRYPT button for too long. Try again, pressing the RESET/
ENCRYPT button for 0.5 to 3 seconds.
If the HomePlug ( ) lights on both powerline devices do not light up, the powerline
devices are not connected. Repeat step 1 in this section. If that doesn’t work, see the
Troubleshooting in Section 6.4 on page 48 for suggestions.
2To add more powerline devices to your network, use any powerline device (A or B) you have
connected to set up a connection with the powerline devices you want to connect (C and D).
3Press the RESET/ENCRYPT button on both powerline devices (Aand C, or Band C) for 0.5 to 3
seconds to add powerline device C. This must be done within 2 minutes (120 seconds) of pressing
the RESET/ENCRYPT button on the PLA.
4Press the RESET/ENCRYPT button on both powerline devices (Aand D, Band Dor Cand D) for
0.5 to 3 seconds to add powerline device D. This must be done within 2 minutes (120 seconds) of
pressing the RESET/ENCRYPT button on the PLA.
