3-3 Control Panel LEDs
The control panel is located on the left handle of the SC417 chassis and 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: The main power button is used to apply or remove power from the power
supply to the system. Turning off system power with this button removes the main
power but keeps standby power supplied to the system. Therefore, you must un-
plug system before servicing.
3-2 Control Panel Buttons
There are two push-buttons located on the left handle of the chassis. From top to
bottom these are a power on/off button and a reset button.
Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM drive
activity when ashing.
Reset: The reset button is used to reboot the system.
