When you press the Power On button, the Power On LED displays a steady
green light, and the system starts a POST (power on self test).
During POST, progress codes appear in the operator panel display.

you press the Power On button, ensure that the power cord, located at the back
of the system unit, is plugged into a grounded electrical outlet. If this does not
solve the problem, go to Chapter 9 on page 9-1. If the LED is not flashing and
OK is not displayed in the operator panel display, go to Chapter 6 on page 6-1.
For a more complete discussion of power on methods, see “System Power-On
