Firmware file transfer methods
To upgrade the firmware of a Automatic Transfer Switch:
• From a networked computer running a Microsoft Windows operating
system, you can use the automated firmware upgrade tool on your CD
or downloaded from the APC Web site.
• From a networked computer on any supported operating system, you
can use FTP or SCP to transfer the individual AOS and application
firmware modules.
• For a Automatic Transfer Switch that is not on your network, you can
use XMODEM through a serial connection to transfer the individual
AOS and application firmware modules from your computer to the
Automatic Transfer Switch.
When you transfer individual firmware modules and do not
use the automated firmware upgrade tool to upgrade the
firmware for a Automatic Transfer Switch, you must transfer
the APC Operating System (AOS) module to the Automatic
Transfer Switch before you transfer the application module.
For more information about the firmware modules, see
Firmware files (Automatic Transfer Switch).
