Hard disk drives
All HDDs connect to the system board through the HDD backplane. HDDs are supplied in hot-swappable HDD carriers that fit in
the HDD slots.
CAUTION: Before attempting to remove or install an HDD while the system is running, see the documentation
for the storage controller card to ensure that the host adapter is configured correctly to support hot-swappable
HDD removal and insertion.
CAUTION: Do not turn off or restart your system while the HDD is being formatted. Doing so can cause a HDD
failure.
NOTE: Use only HDDs that have been tested and approved for use with the HDD backplane.
When you format an HDD, allow enough time for the formatting to be completed. Be aware that high-capacity HDDs can take a
number of hours to format.
