2.9 Hard Drive Installation
WARNING!
1. Handle hard drives with extreme care. Hard drives are very delicate.
Dropping a drive onto a hard surface (even from a short distance) and hitting
or touching the circuits on the drives with your tools may all cause damage
to drives.
2. Observe all ESD prevention methods when handling hard drives.
3. Only use screws supplied with the drive canisters. Longer screws may
damage the drive.
2.9.1 Hard Drive Installation Pre-requisites
CAUTION!
The hard drives and drive trays should only be installed into the subsystem once
the subsystem has been mounted into a rack cabinet. If the hard drives are
installed first, the subsystem will be too heavy to place into position and the
possible impact during installation may damage your drives.
Hard drives for the subsystem must be purchased separately. When purchasing the
hard drives, the following factors should be considered:
• Capacity (MB/GB): Use drives with the same capacity. RAID arrays use a
“least-common-denominator” approach. The maximum capacity of each drive
used in the array is the maximum capacity of the smallest drive. Use drives of
the same capacity.
• Profile: The drive trays and bays of the system are designed for 3.5-inch wide
x 1-inch high hard drives. It is highly recommended that you do not try to use
drives of any other size.
• Drive type: The subsystem described in this manual can use either SATA-II or
SATA-I hard drives.
2.9.2 Drive Installation
Step 1. Place the SATA hard drive into the drive tray (as shown in Figure
2-4) making sure that the hard drive is oriented in such a way that
the drive’s SATA connector is facing the back of the drive tray.
