SZ 3.5.1 and 3.4.2 (latest native releases) install a .noarch.patch file. If you have Zones under 3.5.1 or 3.4.2 for versions 3.2.1 or 3.1.2, you install .ksp files. Please see the descriptions on the SZ firmware download pages. They have the exact filenames and extentions for your reference. SZ-100 and vSZ-E controllers need to be upgraded to 3.4.2 or 3.5.1 presently.
Management has decided to create .noarch.patch files to directly upgrade systems that are running 3.2.1 and 3.1.2 in native mode (such as SZ-100/vSZ-E) and ZD 9.7.2, and these should come before the end of November.
