Upgrade Cisco c220 M3 Rack Server with Host Upgrade Utility

[DAVID]

I need to upgrade a UCS C220 M3 to the latest release 3.0(4s) but the current version 3.0(4i) uses adobe flash so I need to know the steps to upgrade via SSH instead of the browser and KVM

UCS docs are easily google'able:

 I saw this but the upgrade file is an all in one ISO file and the docs are showing bin files

Guides for obtaining the .bin files using `getfw` are on the same page:

Depending on the Linux version you use be aware of:

From the docs, I can upgrade using the ISO or I can extract the files for the BIOS and CMIC into separate bin files and upgrade separately.  However, if I choose to upgrade using the ISO file via TFTP the upgrade process shows INVALID_FILE_EXTENSION
