The files can be downloaded either as .zip files or as .iso images (for CD).

This update is NOT a complete image, the HMC needs to be at level 7.3.1 first. Some service packs are available for 7.3.2 release as well which should be installed.

The installation can be performed using either CDs (has to be done locally) or using network acces like FTP to the .zip files.

Do not forget to perform a compelete backup before you upgrade.
