That means to type the command
R < Return >

Using Configuration Control Mode

Before you use Configuration Control Mode, ensure that your system console interface
has been properly configured. Refer to the 'System Console and System Unit Configu-
rations' section earlier in this appendix for that procedure.
New System Unit First Turn-On
Your system unit's Boot Mode determines whether it runs Domain compatible or HP-
UX compatible operating systems. New system units display their Boot Mode selection
in following two ways:
•
• The power-up display has a Configuration Control menu that may be accessed
Boot Mode LED Patterns
When you first power-up your system unit, the middle eight front panel LEDs all turn
on, then off. After the left side of the power-up display appears, the fourth yellow
LED down, (to the right if the LED display is horizontal), blinks at a high rate for
about three seconds. During the time the fourth LED blinks, the top (or left,) two yel-
low LEDs light to indicate the current Boot Mode selection. Table C-3 lists these LED
patterns.
A special LED pattern appears a few seconds after the system unit gets pow-
ered up. The pattern appears after the power up display has completed on the
left side of the screen and before the Configuration Control menu appears.
to find out what the Boot Mode selection is. You can change the selection if
necessary.
