Chapter 3 Managing Your PLA-4xx

PLA-4xx Series User’s Guide

Use the Firmware screen to update the firmware on the PLA-4xx directly connected to the 
computer running the configuration utility.
Firmware is the software which is embedded in the PLA-4xx. This software contains 
processing instructions for how the PLA-4xx sends and receives information in a secure way.
Parameter Information Block (PIB) is similar to firmware. It contains the most basic operating 
instructions for the PLA-4xx such as how to power up and how to load the firmware. 
You can check the ZyXEL website for firmware upgrades for your PLA-4xx.

Network 

Password

The default network password of PLA-4xxs is “HomePlugAV”. The PLA-4xxs use the 

same network password to recognize and communicate with each other over the 

powerline network. If you change the password of one device on the network, it will no 

longer be recognized as part of that network.
If you change the network password, make sure you change the password for all of 

the powerline adapters that you want to be part of your powerline network.
The network password can be from 1 to 64 alphanumeric characters in length; spaces 

are not allowed.

Save 

Click this to apply your changes. The new Network Password is applied to the 

selected powerline adapter.
