Power: The main power switch is used to apply or remove power from the power
supply to the server system. Turning off 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.
3-2 Control Panel Button and LEDs
There are two push-buttons located on the front of the chassis. These are (in order
from left to right) a reset button and a power on/off button.
Unit Identification LED : The Unit Identification LED is used to indicate fan failure,
power failure, overheat condition, or to identify the unit within a large rack instal-
lation. The feature requires a motherboard that supports the Universal Information
LED.
When this LED blinks red quickly, it indicates a fan failure and when blinking red
slowly a power failure. This LED will be blue when used for UID (Unit Identifier).
When on continuously red, it indicates an overheat condition, which may be caused
by cables obstructing the airflow in the system or the ambient room temperature
being too warm. See the table below for descriptions of the LED states
