PLA-4xx Series User’s Guide

1.4.1 Passwords

You use two types of passwords in the HomePlug AV powerline network. The following table

describes the differences between the passwords.

1.4.2 Setting Up Security

Use the PLA-4xx Series Configuration Utility to set up security on the PLA-4xx or other

HomePlug AV compliant powerline adapters. Although the PLA-4xx is a “plug-and-play”

network expanding solution there are several reasons for enabling security on the powerline

network in your home.

1 It’s easy and only requires you to change a password.

2 It’s a good idea to ensure privacy of your communication. When you use the PLA-4xx

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 to make sure that only permitted powerline

adapters can communicate in your network. See Section 3.1.1 on page 26 for

information on setting up a private network.

" Buildings and even streets may share a coaxial cable connection. If your

powerline network uses a coaxial cable, the network will probably extend

outside your premises. In this case make your network more secure with a

private network password.

3 You may need to change the password to create multiple powerline networks. See the

next section for more information on how to set up a multiple network.

Table 1 Password Summary

PASSWORD DESCRIPTION

Private Network

Password

All powerline adapters that follow the HomePlug AV standard are

shipped with the same powerline network password “HomePlugAV”.

Change this password via the PLA-4xx Series Configuration

Utility to create a private network. See Section 3.3 on page 26.

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 PLA-4xx

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).
