Starting The System Unit - IBM R/S6000 7012 300 Series Operator's Manual

Attention: The Reset button is active when the key mode switch is in the Normal or Service
position, and pressing the Reset button can cause data to be damaged or lost if the
operating system is still running.
If there is a problem with the system unit, refer to the AIX Version 4 Problem Solving Guide
and Reference before setting the key mode switch in the Service position or pressing the
Reset button.

Starting the System Unit

The front of your system unit will look like one of the following illustrations.
See this illustration for starting the system unit.
1. Set the key mode switch to the Normal position.
2. Set the power switches of the attached devices to On.
3. Start the system unit by setting the power switch to On (I).
4. If power-on light does not come on when you set the power switch to On, ensure that the
power cord, located at the back of the system unit, is plugged into a grounded electrical
wall outlet. If this does not solve the problem, refer to the AIX Version 4 Problem Solving
Guide and Reference.
When you set the power switch to On, the power-on light comes on and the system starts a
power-on self-test (POST).
During POST, numbers are displayed in the 3-digit display.
