ZyXEL Communications PLA-407 User Manual

Chapter 6 The OS X Configuration Utility

PLA-407 User’s Guide

Use the firmware upgrade tool to upgrade firmware to the Powerline device 
directly connected to your computer.

To upgrade to the latest firmware, use the firmware upgrade tool on the CD 
included with your PLA-407.  Make sure you also use the latest PLA-4xx Series 
Configuration Utility; older utilities may not be compatible with PLA-407s using 
the latest firmware.

• If the firmware version of devices in your Powerline network is greater than 

3.0.5, then you may only need to upgrade the utility; otherwise you must 

upgrade both the utility and the firmware!

• Be sure to upload the correct model firmware as uploading the wrong model 

firmware may damage your device.

• The firmware is included in the upgrade tool. You do not need to download the 

firmware separately.

• After you upgrade firmware, all settings that you configured in the utility revert 

to their factory defaults. Before upgrading, write down your current settings. 

After you upgrade the firmware, you need to reconfigure your device using the 

utility.

• Your device automatically reboots after you upload the firmware.
• You cannot downgrade firmware to an older version firmware.

Connect the Powerline device to be upgraded to your computer.

Close the Configuration Utility and Firmware Detection Tool if either of them 
are open.
