Chapter 8 HomePlug AV 8.2.1 Setting Up a Private Powerline Network To prevent others compromising your network security, you can create a private network. Create a private network by changing the network password only on the powerline adapters you want to communicate in your network. Only the powerline adapters with the same network password can communicate in your network. The following figure shows a scenario A - where all the powerline adapters have the same network password (1) and scenario B - where some adapters use password 1 and some use password 2. Figure 45 Powerline Network Scenario A 1 1 B 1 2 1 1 1 2 1 1 1 2 In both cases the powerline adapters reside on the same electrical circuit. In scenario A all the powerline adapters can communicate with each other. In scenario B only the adapters with the same password can receive and unscramble communication between each other. 8.2.2 Setting Up Multiple Powerline 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. Connect one powerline adapter to a router or switch on the first Ethernet network and assign a network password (for example, "Password1") to this powerline adapter. Add additional powerline adapters to your network by plugging them into your powerline outlets and assigning them the same network password, "Password1". This completes the configuration of your first powerline network. Connect another powerline adapter to a router or switch on the second Ethernet network and assign a different network password (for example "Password2") to this powerline adapter. Again, add additional powerline adapters and assign them the same second network password, "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 password can communicate with each other. The following figure shows two private powerline networks on the same electrical circuit. PLA450 User's Guide 87

8.2.1

Setting Up a Private Powerline Network

To prevent others compromising your network security, you can create a private network.

Create a private network by changing the network password only on the powerline adapters

you want to communicate in your network. Only the powerline adapters with the same

network password can communicate in your network.

The following figure shows a scenario

- where all the powerline adapters have the same

network password (

) and scenario

- where some adapters use password

and some use

password

Figure 45

Powerline Network Scenario

In both cases the powerline adapters reside on the same electrical circuit. In scenario

all the

powerline adapters can communicate with each other. In scenario

only the adapters with the

same password can receive and unscramble communication between each other.

8.2.2

Setting Up Multiple Powerline 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.

Connect one powerline adapter to a router or switch on the first Ethernet network and assign a

network password (for example, “Password1”) to this powerline adapter. Add additional

powerline adapters to your network by plugging them into your powerline outlets and

assigning them the same network password, “Password1”. This completes the configuration of

your first powerline network.

Connect another powerline adapter to a router or switch on the second Ethernet network and

assign a different network password (for example “Password2”) to this powerline adapter.

Again, add additional powerline adapters and assign them the same second network password,

“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 password can

communicate with each other. The following figure shows two private powerline networks on

the same electrical circuit.
