APC AP8861 Manuel D’Utilisation

When you upgrade the firmware on the Rack PDU:

•  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 PDUs support the 
same features in the same manner.

A firmware release has three modules, and they must be upgraded (that is, placed on the Rack PDU) in this 

order: 

•  a boot monitor (

) module

•  an American Power Conversion Operating System (

) module

•  an 

 module

(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.

Note: Upgrade the bootmon module first, then the AOS module, and finally, the application module by 
placing them on the Rack PDU in that order.
