ZyXEL Communications PLA-407 User Manual

PLA-407 User’s Guide

Use the Firmware Upgrade Tool to ensure you have the latest firmware (version 
4.0.1 or later) on your PLA-407(s).

You need to upgrade all your PLA-407s to the latest firmware to ensure they can 
connect with each other and they are compatible with the latest version Utility.

If your firmware is an early version (earlier than 4.0.1), then upgrade your 
firmware using the Firmware Upgrade Tool.

Use the firmware upgrade tool to upgrade your PLA-407’s firmware to the latest 
version. 

You can use this tool to upgrade the firmware on the Powerline device directly 
connected to your computer. This is necessary as devices with ZyXEL’s early 
version firmware are not compatible with the latest Utility or with devices running 
ZyXEL’s latest version firmware.

At the time of writing, firmware version 4.0.1 is only available to PLA-407. This 
firmware version is compatible with version 3.3.4. Firmware version 3.3.4 is 
available to PLA-401 v3, PLA-402 v3 and PLA-407. 

Note: The firmware is included in the Tool. You do not need to download the firmware 

separately.
