The power-on indicator lights when the
system power is on.
The power button controls the DC
power supply output to the system.
When the system bezel is installed, the

NOTE: When powering on the system, the
video monitor can take up to 25 seconds
to display an image, depending on the
amount of memory installed in the system.

systems, turning off the system using the
power button causes the system to
perform a graceful shutdown before

press and hold the power button for five
seconds.
