Chassis Install Instructions (734751-001, March 2014)

2 Installing hard drives in the enclosure
Depending on the types of hard disk drives (HDDs) you are using, the following numbers of drives
can be installed in a single enclosure:
• Large form factor (LFF): 12 HDDs
• Small form factor (SFF): 25 HDDs
A variety of disk drive models are supported for use, including dual-ported and single-ported
models. For more information about supported disk drives, see the QuickSpecs for the disk enclosure,
available on the D3000 website.
CAUTION: To prevent improper cooling and thermal damage, operate the enclosure only when
all bays are populated with either a component or a blank.
Disk drive guidelines
CAUTION:
• Follow industry-standard practices when handling disk drives. Internal storage media can be
damaged when drives are shaken, dropped, or roughly placed on a work surface.
• When installing a disk drive, press firmly to make sure the drive is fully seated in the drive
bay and then close the latch handle.
• When removing a disk drive, press the release button and pull the drive only slightly out of
the enclosure. Then, to allow time for the internal disk to stop rotating, wait approximately 10
seconds before completely removing the drive from the enclosure.
• Always populate hard drive bays starting with the lowest bay number. If only one hard drive
is used, install it in the bay with the lowest device number.
• Disk drives are hot-pluggable.
• SAS and SATA disk drives may be installed in the same enclosure, but cannot be included in
the same RAID logical volume.
Installing a disk drive
