How to Power On the System

Before You Begin
If a terminal or local console is not already connected to the system, you need to
install one before continuing the startup procedure.
See "About Setting Up a Console" on page 19.
Note – Do not use this power-on procedure if you have just installed an internal or
external storage device, or any new part that plugs into the main logic board. To
power on the system after adding any of these options, see "How to Initiate a
Reconfiguration Boot" on page 29.
What to Do
Caution – Never move the system when system power is on. Movement can cause
catastrophic disk drive failure. Always power off the system before moving it.
Caution – Before you power on the system, make sure that the side access panel
and all plastic outer panels and doors are properly installed.
Caution – Removing the side access panel or removable media assembly activates
the system power interlock switches. This safety mechanism prevents all DC
voltages (except 5V standby power) from reaching any internal component when the
side panel or removable media assembly is removed and the front panel keyswitch
is in the Power-on position ( ).
1. Turn on power to any peripherals and external storage devices.
Read the documentation supplied with the device for specific instructions.
