CAUTION: : Many
repairs may only be done by a certified service technician. You should
only perform troubleshooting and simple repairs as authorized in your product
documentation, or as directed by the online or telephone service and support
team. Damage due to servicing that is not authorized by Dell is not covered by

CAUTION: : Use only hard disk drives that have been tested and approved for
use with the SAS backplane.
CAUTION: : When
installing a hard disk drive, ensure that the adjacent hard disk drives
are fully installed. Inserting a hard disk drive carrier and attempting
to lock its handle next to a partially installed carrier can damage
the partially installed carrier's shield spring and make it unusable.
