SC748 Chassis Manual
4-2
4-2 Control Panel Buttons
There are two push-buttons located on the front of the chassis. These are power
on/off button and a reset button.
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.
4-3 Control Panel LEDs
The control panel located on the front of the SC748 chassis has six LEDs. These
LEDs provide you with critical information related to different parts of the system.
This section explains what each LED indicates when illuminated and any corrective
action you may need to take.
Power:
•
Indicates power is being supplied to the system's power supply units.
This LED should normally be illuminated when the system is operating.
Overheat/Fan Fail: When this LED flashes it indicates a fan failure. When continu -
ously on (not flashing) 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. Check the routing of the cables and make sure all fans are present and
operating normally. You should also check to make sure that the chassis covers
are installed. Finally, verify that the heatsinks are installed properly. This LED will
remain flashing or on as long as the overheat condition exists.
