Hard Drives
Depending on the configuration, your system supports up to four 2.5 inch, hot-swappable SAS or SATA
SSDs.
NOTE: SSD/SAS/SATA hard drives cannot be mixed in a system.
The hot-swappable hard drives connect to the system board through the hard-drive backplane. Hot-
swappable 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 hot-swappable 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.
Removing A Hot-Swap Hard Drive
CAUTION: To prevent data loss, ensure that your operating system supports hot-swap drive
installation. See the documentation supplied with your operating system.
1. From the management software, prepare the hard drive for removal. Wait until the indicators on the
hard-drive carrier signal that the hard drive can be removed safely. For more information, see the
documentation for the storage controller.
If the hard drive is online, the green activity/fault indicator flashes as the drive is turned off. When the
hard-drive indicators are off, the hard drive is ready for removal.
2. Loosen the two thumb screws on the front of the hard-drive carrier.
3. Hold the thumb screws and slide the hard-drive carrier out until it is free of the hard-drive slot.
CAUTION: To maintain proper system cooling, all unused hard-drive slots must have empty
hard-drive carriers installed.
