5. Shutdown the controller with the following command:
SHUTDOWN THIS_CONTROLLER

Failure to shut down the controller in this step could result in

CAUTION
Before continuing, wait until the Reset button on the controller
stops flashing (lit continuously). This indicates that unwritten
data is flushed from the cache module.
