Hello,   The SUU you're referring to isn't a bootable file. The Lifecycle controller may be able to interact with the SUU, but I'm not certain this generation was capable of doing so. I don't believe that it could, but it's something worth double checking. Updating in-band won't be an option, because Debian isn't supported. If the LCC doesn't work with the SUU, then It think you would be best served by grabbing the Dell Support Live image, booting to that, and running individual firmware packages through there. The Support Live image is CentOS based and shouldn't get hung up on OS version scans.   There is also the Repository Manager tool, which can be used to create your own bootable firmware update image, but there would be a fair amount of effort involved. I've only created one myself once and I remember it being a bit tricky.,
Hello all, I have old R300 server with Debian 10 os. I would like to ask how to update firmware (NIC, BMC, Perc etc.). On R300 support page i found something like Dell Server Update Utility - 11,5 GB ISO file. Is this file containe a firmwares? Should I just boot from this file and will there be some update options?   Greetings.
