Chapter 1 Introducing the PLA-4xx

PLA-4xx Series User’s Guide

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 5.3 on page

45 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 name.

3 You 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.

1.6 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.

1 Connect 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.

2 Connect 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.
