Installing A Hot-Swap Hard Drive

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 your
warranty. Read and follow the safety instructions that came with the product.
CAUTION: Use only hard drives that have been tested and approved for use with the hard-drive backplane.
CAUTION: Combining SAS and SATA hard drives in the same RAID volume is not supported.
CAUTION: When installing a hard drive, ensure that the adjacent drives are fully installed. Inserting a hard-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.
CAUTION: To prevent data loss, ensure that your operating system supports hot-swap drive installation. See the
documentation supplied with your operating system.
CAUTION: When a replacement hot-swappable hard drive is installed and the system is powered on, the hard drive
automatically begins to rebuild. Make absolutely sure that the replacement hard drive is blank or contains data that
you wish to have over-written. Any data on the replacement hard drive is immediately lost after the hard drive is
installed.
