Hard drives
All hard drives connect to the system board through the hard-drive backplane. Hard drives are supplied in
hot-swappable hard-drive carriers that fit in the hard-drive slots.
CAUTION: Before attempting to remove or install a hard drive 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-swap hard drive removal and insertion.
CAUTION: Do not turn off or reboot your system while the hard drive is being formatted. Doing
so can cause a hard drive failure.
NOTE: Use only hard drives that have been tested and approved for use with the hard-drive
backplane.
When you format a hard drive, allow enough time for the formatting to be completed. Be aware that
high-capacity hard drives can take a number of hours to format.
