How to Upgrade Firmware
Benefits of upgrading firmware
When you upgrade the firmware on the Rack Power Filter:
• 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 Rack Power Filters
support the same features in the same manner.
Firmware files
A firmware version consists of three modules: An APC Operating System (AOS) module, an application
module, and a boot monitor (bootmon) module. Each module contains one or more Cyclical Redundancy
Checks (CRCs) to protect its data from corruption during transfer.
The APC Operating System (AOS), application, and boot monitor module files used with the Rack
Power Filter 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: Identifies whether the file is the APC Operating System (AOS) module, the application
module, or the boot monitor module for the Rack Power Filter.
• version: The version number of the file.
• bin: Indicates that this is a binary file.
