SC846 Chassis Manual
3-2
3-3 Control Panel LEDs
The control panel located on the front of the SC846 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.
Power:
The main power button 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 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.
Overheat/Fan Fail:
When this LED flashes, it indicates a fan failure. When con
-
tinuously 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 pres-
ent 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.
