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.

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

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.

2.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.

3.Remove the drive tray. To remove the drive tray from the enclosure, the key-lock must be unlocked. (See Figure 6.9) To do this, turn the key-lock on the front of the drive tray until the groove on its face is in a horizontal orientation.

4.Remove the drive tray along with the hard drive in it. Once the drive tray is dislodged from the chassis, gently and carefully withdraw the drive tray from the chassis.

5.Remove the hard drive from the drive tray: Loosen the four retention screws (two on each side) to remove the hard drive from the drive tray.

6.Install the new hard drive:
