Upgrading Firmware
Benefits of upgrading firmware
When you upgrade the firmware on the ATS:
• You obtain the latest bug fixes and performance improvements.
• New features become available for immediate use.
Keeping the firmware versions consistent across your network ensures that all ATSs support the same
features in the same manner. Here, upgrading simply means placing the module files on the ATS; there is no
installation required. Check regularly on www.apc.com for any new upgrades
Firmware module files
A firmware release has three modules, and they must be upgraded (that is, placed on the Rack ATS) in the
same order as shown in the table below. NOTE: It is possible to skip upgrading the bootmon file if it is already
the same version as the file located on the card
(Each module contains one or more Cyclical Redundancy Checks (CRCs) to protect its data from corruption).
The boot monitor module, the AOS, and the application file names share the same basic format:
apc_hardware-version_type_firmware-version.bin
• apc: Indicates the context.
• hardware-version: hw0n where n identifies the hardware version on which you can use this
file.
• type: Identifies which module.
• version: The version number of the file.
• bin: Indicates that this is a binary file.
Firmware File Transfer Methods
NOTE: Upgrade the bootmon module first, then the AOS module, and finally, the application module by
placing them on the ATS in that order.
Obtain the free, latest firmware version from the APC by Schneider Electric web site. To upgrade the firmware
of one or more ATSs, use 1 of these 5 methods:
• On a Windows operating system, use the Firmware Upgrade Utility downloaded from the web
site www.apc.com.
• On any supported operating system, use FTP or SCP to transfer the individual AOS and
application firmware modules.
• For a Rack ATS that is NOT on your network, use XMODEM through a serial connection to
transfer the individual firmware modules from your computer to the Rack ATS .
• Use a USB drive to transfer the individual firmware modules from your computer.
• For upgrades to multiple ATSs, see “Upgrading the firmware on multiple Rack ATSs” and “Using
the Firmware Upgrade Utility for multiple upgrades on Windows”
