APC AP7900 Manual Do Utilizador

If all computers on your 

network are running Linux, you must upgrade the firmware of your Rack 
PDUs manually, i.e., by using the separate APC firmware modules (AOS 
module and application module).

You can obtain the individual firmware modules you need for a manual 
firmware upgrade from the support section of the APC Web site 

If you have a networked computer running a supported Microsoft 
Windows operating system on your network, you can use the tool 
described in 

 to upgrade the firmware of a Switched Rack PDU 

automatically over the network. This tool automates the entire 
upgrade process, even if your current firmware is a 1.x.x version.

When performing a manual upgrade, not using the automated 
tool, you cannot upgrade the AOS firmware module of any APC 
device directly from firmware version 1.x.x to firmware version 
2.1.0 or later. The upgrade attempt will fail. You must first upgrade 
to the latest available 2.0.x version of the AOS module and then to 
the later version.
