What you say does not make the need clear. WHY can you not access the console? Do you mean REMOTE console access, or is there a problem logging in at the local keyboard? Does the monitor display a GUI login prompt?
Whether or not you can remotely access your servers in single-user mode depends on the manufacturer. Some provide a means of remote access, some do not. But Linux per se does not support this, as there is no networking enabled in single-user mode.
