Drives
Drive installation guidelines
Drives are available in hot-swappable drive carriers that fit in the front drive slots of the PowerEdge MX840c sled.
CAUTION:
Before attempting to remove or install a drive while the sled is running, see the documentation for
the storage controller card to ensure that the host adapter is configured correctly to support hot-swap drive
removal and insertion.
CAUTION: Do not power off or restart your sled while the drive is being formatted. Doing so can cause a drive
failure.
When you format a drive, allow enough time for the formatting to be complete. Be aware that high-capacity drives can take a
long time to format.
Removing a drive blank
