After a power cycle the server it's behaving properly. Since it was already depooled I'm not repooling it

That sounds like a hang in the NIC, but I doubt we have any useful hardware diagnostics/logging on that level.

The host also shows that power supplies are not redundant.. which had a comment linking to T177403 -> T177228.

And support has expired (

Should we rather create a decom ticket for it?
