You may download the individual .rpm and .xml files for Power
Subsystem firmware from this location to your server, an ftp server, or a
CD-ROM (both files are required). Make sure the file names have the
format 02EP3xx_yyy_zzz, with an extension of .rpm and .xml before copying
them to your server, an ftp server or CD-ROM. If using a CD-ROM,
copy the .rpm and .xml files to the CD-ROM using a local CD-ROM burner utility.
Another method is to download the .iso file and create a CD-ROM
to use with your HMC.
Note: If your HMC is not internet-connected you will need to download
the new firmware level to a CD-ROM or ftp server.
The method used to install new firmware will depend on the release level
of firmware which is currently installed on your server. The release level
can be determined by the prefix of the new firmware's filename.
Where XXX = release level
