Preparing the appliance
Best practices recommend removing the appliance from the rack to access the inside of the chassis. Alternatively you can either pull out the appliance on its rails. Be sure that the appliance and rack are stable.
Turn off the appliance properly and disconnect it from AC power sources. A soft shutdown informs the appliance operating system to stop and close all active processes. After the operating system stops all of the processes, the appliance turns itself off.
Warning:
Never turn off the appliance by using the power button on the control panel. Using the power button to turn off the appliance can cause data loss or corruption.
To perform a soft shutdown of the appliance
- Log on to the Flex Appliance Shell Menu.
- Enter system shutdown.
- Verify that the appliance is completely turned off. All LEDs are off. Fans are not running.
- Remove the power cords that connect the appliance to the rack Power Distribution Units (PDUs).
The following procedure explains the process of removing the appliance from the rack.
