Overheat/Fan Fail:
•
When this LED flashes it indicates a fan failure. When
continuously 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.

The control panel located on the front of the SC503 chassis has five 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.

The reset button is used to reboot the system. A needle, pen, or other
small device is required to activate this button and reset the system
4-2 Control Panel Buttons
