Recreating the storage dx4000 - Stuck (recreate storage success)

I succeeded recreating my storage after a diskpart clean all on my 4 hdd (5-6 hours each) but when I try to recover the OS, I get always ‘server not found’ even aftfer following the ‘dhcp direct connection’ (Server was not found - #3 by Sam_22)

Is there a default IP address in the ‘recovery started’ mode?
Is there a way to hard reset the server without a desktop connection?
