USER’S GUIDE AUTOMATIC TRANSFER SWITCH

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
• The version of the tool on the APC Automatic Transfer Switch Utility
CD will upgrade your device to the latest AOS and application modules
available when the CD was released.
• If a later firmware upgrade is available, 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, the Automatic
Transfer Switch) and download the automated tool, not the individual
firmware modules.
If the AOS firmware module you already have is a 1.x.x version, the
executable tool must perform two consecutive upgrades:
• The first upgrade is from version 1.x.x to the latest available 2.0.x
version of the AOS firmware module.
• The second upgrade is from the 2.0.x version to the most recently
released version of the AOS module.
The tool therefore contains firmware modules for both upgrades.
Each upgrade tool is specific to an APC product type. Do not use the tool
from one product CD to upgrade firmware of a different APC product. 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.
