what exactly are trying to do? Do you want to upgrade the firmware of your server or do you want to upgrade the drivers on your OS?
Note that you don't upgrade the firmware of the OS, you upgrade the firmware of the physical components of your server. For example, you can upgrade the BIOS firmware or the network adapter firmware. Drivers are updated at the OS level, so you want to load those files locally to the OS the SCU will only help you load the drivers to a n external storage like the flexflash SD card.
If you just want to upgrade the firmware take a look at the youtube video below, it will give you an idea of the steps you need to take to upgrade the firmware. Note that this is an older process for firmware versions before 1.5, but the overall the process is very similar
If you want to update the drivers on your OS, l recommend to mount the drivers iso on your kvm and update the drivers this way. When you do this the OS will see that you are presenting a CD/DVD with the drivers included.
