Console hardware errors

When a console hardware error occurs, one or more of the following can happen:

Error messages are centered on the screen. The remainder of the screen is blank. See Recovery actions for error messages centered on the screen.
The screen blanks out, but no error message appears.
The screen appears normal, but the keyboard is locked and the operator cannot enter commands. See Recovery actions for a locked keyboard.
