How to Upgrade Firmware
Benefits of upgrading firmware
Upgrading the firmware on the cooling unit has the following benefits:
• New firmware has 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 cooling units
support the same features in the same manner.
Firmware files
A firmware version consists of two modules: An APC Operating System (AOS) module and an
application module. Each module contains one or more Cyclical Redundancy Checks (CRCs) to protect
its data from corruption during transfer.
The AOS and application module files used with the cooling unit share the same basic format:
apc_hardware-version_type_firmware-version.bin
• apc: Indicates that this is an APC file.
• hardware-version:
hw0x identifies the version of the hardware on which you can
use this binary file.
• type:
aos if the file is the AOS module, or acrp if the file is the application module for
the cooling unit.
• firmware-version: The version number of the file.
•
bin: Indicates that this is a binary file.
Obtain the latest firmware version
Automated upgrade tool for Microsoft Windows systems. An upgrade tool automates the
transferring of the firmware modules on any supported Windows operating system. Obtain the latest
version of the tool at no cost from www.apc.com/tools/download. At this Web page, find the latest
firmware release for your APC product and download the automated tool. Never use the tool for one
APC product to upgrade the firmware of another product.
