Control Panel Buttons

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.
Reset: The reset button is used to reboot the system.
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 but-
ton removes the main power but keeps standby power supplied to the system.
Therefore, you must unplug system before servicing.

Control Panel LEDs

The control panel located on the front of the SC812L chassis has fi ve 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.
Overheat/Fan Fail: When this LED fl ashes it indicates a fan failure. When
continuously on (not fl ashing) it indicates an overheat condition, which may be
caused by cables obstructing the airfl ow in the system or the ambient room tem-
perature 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 fl ashing or on as long as the overheat condition exists.
