How to Enter Console Mode
Enter console mode by turning on the system power or pressing
the halt button. If the system is running software, shut down
the system software before you enter console mode. Refer to
‘‘Shutting Down the System Software’’ section for information
about shutting down the system software. The system enters
console mode automatically when system software is shut down.
When you turn on the system power, the system completes a
power-up self-test before displaying the console prompt.
If the system displays the
R>
prompt, you can use only the
boot and password commands until you enter the password.
To enter the password, type passwd and press Return. At the
pwd:
prompt, type the password and press Return. When you
have access to all console commands, the system displays the
>>
prompt.
For information about setting and removing console command
passwords, refer to ‘‘Using Console Command Passwords’’
section of this chapter.
How to Enter Operating Mode
Enter operating mode by booting the system. Specific booting
instructions are contained in ‘‘Booting the System Software’’
section of this chapter.
If the system is set up for autoboot, the system goes directly to
operating mode after the power-up self-test without displaying
the console prompt. Autoboot performs on power-up when the
halt action environment variable has been set to b and the boot
environment variable has been set to a meaningful bootpath.
For further command information, refer to ‘‘boot Command’’ and
‘‘setenv Command’’sections in Appendix C.
