Obtain the latest firmware version
Automated upgrade tool for Microsoft Windows systems. An automated
self-extracting executable tool combines the firmware modules that you need to
automate your upgrades on any supported Windows operating system.
• You can obtain an updated version of the tool at no cost from the support section of
the APC Web site www.apc.com/tools/download. At this Web page, find the latest
firmware release for your APC product (in this case, your Rack PDU) and download
the automated tool, not the individual firmware modules.
Each upgrade tool is specific to an APC product type. If you use a version of the tool
from the APC Web site, make sure that you use the upgrade tool that corresponds with
your APC product type.
