Chapter 2: Installation

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.
