I bought a used R730 server from an online store. The firmware is very old. Now I upgraded some firmware using SUU.

But I will also use Dell's Https|Http repository to check for available updates

But... Idarc 8 version 2.83.83.83 tells me: LC023: Unable to access network share. Check network share access credentials (IP address, username, password, share type, etc.). See the Lifecycle Controller Profiles documentation for more details.

I also tried again with Lifecycle Controller, it told me: Unable to save IPv4 and IPv6 network settings (SWC001), I tried shutting down the server and disconnecting the power cord, but it didn't work. If I use a static address. Lifecycle Controller tells me that there is no network cable connected.
