CAUTION:  Always populate drive bays with either a hard drive or blank. Operating the server 
without installing a hard drive or blank results in improper airflow and improper cooling that 
can lead to thermal damage. 
To replace the hard drive blank, slide the blank into the bay until it locks into place.
