Turning on the System and Monitor
NOTE:
The system may take a few minutes to display on the screen due to
processor and memory initialization that is performed before the video initialization.
The delay is proportional to the amount of memory that is installed.
Press the power button on the system and the monitor (optional). The power
indicators should light. Adjust the monitor's controls until the displayed
image is satisfactory.
If you have purchased the optional system bezel, install it after turning on
the system.
