Yes, you would need to update the AOS and APP files - more info can be found here: http://www.schneider-electric.com/en/faqs/index?page=content&id=FA156047
The latest rev is v3.9.2, you can download it here - ftp://restrict:Kopfirstname.lastname@example.org/restricted/hardware/nmcard/firmware/rpdu/392/apc_hw02_aos392_rpdu392.exe
It appears the username/pw has changed? Anybody got a link to the 3.9.2 software that works?
Copy and paste the link in the original post, don't try clicking on it. I just tried that (IE11) and it asked me where I wanted to store the downloaded file.
