Installation guide

If you are preparing to reboot your system from a powered-down state,
follow these steps:
1. Confirm that the hardware and all peripheral devices are connected.
Refer to the operator’s guide for your hardware for information and
instructions for interpreting diagnostic output.
2. Power up the hardware and peripheral devices. Remember to power up
all devices that you powered down earlier. Refer to the operator’s
manual or the hardware user’s guide for instructions on starting your
hardware and peripherals.
3. Confirm that the hardware completed its restart and diagnostic
operations. Most hardware provides a diagnostic check as a routine
part of its startup operation. Refer to the operator’s manual for your
hardware for information about your hardware’s restart and diagnostic
operations.
4. Wait for the console prompt (
>>>). If you have enabled your system to
boot automatically upon powerup, press the halt button to display the
console prompt. Refer to the hardware operator’s guide for the location
of the halt button on your system. See Section 3.3 for more information
on setting the default boot action for your system.
5. Decide which startup mode you want to initiate:
• If you have tasks you need to accomplish and want the system to
restrict access to all users but root, plan to boot to single-user mode.
• If you do not require single-user access and you want the system to
initialize full functionality, plan to boot to one of the multiuser
modes: multiuser without networking or multiuser with
networking.
6. Enter the boot command that corresponds to the desired startup mode.
Refer to Section 3.3 for the commands and procedures required to boot
your system.
