4-2 Control Panel Buttons
There are two push-buttons located on the front of the chassis. These are the power
on/off button and the reset button.
Power:
The main power switch is used to apply or remove power from the power
supply to the server system. Turning off the system power with this button removes
the main power but keeps standby power supplied to the system. Therefore, you
must unplug system before servicing.
Reset:
The reset button is used to reboot the system.
