the drive tray slot open for an extended period of time. If the drive tray slot is left unoccu-

pied for an extended period of time, the airflow will be disrupted and subsystem compo-

nents will overheat and may be permanently damaged.

6.7.2

Replacing a Failed Hard Drive

To replace a hard drive, please follow these steps:

Hard drives for the subsystem can 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 can use either SATA-II or SATA-I hard drives.

Identify the drive tray that contains the hard drive that needs to be replaced.

Open the front flap: Once the drive tray has been identified, push the release button at

the drive bezel. (See

Figure 6.8

) The front bezel will automatically be lifted and the drive

tray should be easily dislodged from the chassis.

CAUTION!

•

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.

•

Observe all ESD prevention methods when handling hard drives.

•

Only use screws supplied with the drive canisters. Longer screws may damage the drive.

CAUTION!

The hard drives and drive trays should only be installed into the subsystem once the sub-

system has been mounted into a rack cabinet. If the hard drives are installed first, the sub-

system will be too heavy to place into position and the possible impact during installation may

damage your drives.

CAUTION!

Replacing the wrong drive in an array can fatally fail a RAID configuration. You should identify

a failed drive from the Bosch RAIDWatch GUI screen, by checking the drive slot ID in the termi-

nal screen, by checking the LEDs on the drive tray panel, and/or use the identify/flash drive

function in firmware.
