3-3 Control Panel LEDs
The control panel located on the left handle of the SC847BEC1/C2 and SC847BA
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.

There are two push-buttons located on the left handle of the chassis. These are
(in order from top to bottom) a power on/off button and a reset button.

activity when flashing.
