6.3 Firmware Upgrade Tool
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-401 Series. Make sure you also use the latest PLA-4xx
Series Configuration Utility; older utilities may not be compatible with PLA-401
Seriess using the latest firmware.
6.3.1 Notes on Upgrading 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.
6.3.2 Procedure to Upgrade Firmware
1
Connect the powerline device to be upgraded to your computer.
2
Close the Configuration Utility and Firmware Detection Tool if either of them
are open.
