This section provides basic information about the drive carriers
and carrier removal instructions. For drive carrier installation
instructions, see
page 2-9
.
About the Drive Carriers
The drive carriers are located on the front of the Storage Enclosure.
(See
Figure 1-1 on page 1-4
.) The drive carriers have a mechanical
button-activated cam system that helps control installation and
removal, and have an optional disk drive shield attached.
Carrier blanks are provided for drive slots without disk drives
installed.
Holes in the front of the drive carriers and carrier blanks allow air
to flow into the enclosure and cool the disk drives and enclosure.
During installation, ensure that the cooling holes in the carriers or
carrier blanks are not obstructed.
Either a drive carrier or a carrier blank must be installed in every
drive slot to maintain proper airflow and cooling inside the
enclosure.
Failed drive carriers can be hot-swapped.
Important Safety Precautions
Before you remove a drive carrier, read these important cautionary
notes:
Caution:
Although the drive carriers are hot-swappable, stop
all I/O activity on the disk drive to be replaced to avoid data
loss. Removing a disk drive during I/O activity could also
hang the host system.
Caution:
Do not
attempt to remove more than one drive carrier
or carrier blank at one time. Damage to the drive carrier
locking tabs can occur if adjacent drive carriers are removed
at the same time.
