Power:
The main power button is used to apply or remove power from the power
supply to the system. When the power is on, the power button will be lighted by a
blue LED. Turning off the system power with this button will cause the blue LED
to turn off and will remove the main power, but will keep standby power supplied
to the system. Therefore, you must unplug system before servicing the system.
3-3 Control Panel LEDs
The control panel located on the front of the SC731 chassis has three 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.
