RAID Subsystem DVA-12T Installation Manual

 

 

To replace a cooling module, please follow these instructions:

1.Remove the cooling module. Two (2) clips secure the cooling module to the subsystem. To remove the cooling module push these clips together and gently pull the cooling module out of the enclosure. (See Figure 6.10)

Fig. 6.10 Removing the Cooling Module

2.Forcing or slamming a module into place can damage the pins on the module connectors either on the module itself or on the connectors of system backplane.

3.Install the new cooling module. To do this, align the replacement cooling module with the bay from which the faulty one was removed. Then gently slide the new cooling module into the enclosure subsystem.

6.7Replacing a Failed Hard Drive

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 maxi- mum capacity of the smallest drive. Choose big drives with the same storage 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 RAID subsystem described in this manual can use SATA-I or SATA-II hard drives. Please ensure that you purchase the correct hard drives.

CAUTION!

•

The hard drives and drive trays should only be installed into the subsystem after the sub- system has been mounted into a rack cabinet. If the hard drives are installed first, the subsystem will be too heavy to lift and the possible impact during installation may dam- age your drives.

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 cause damage to the drives.

Observe all ESD prevention methods when installing drives.

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

Hard Drive Maintenance Overview

•

•

Hot-swappable drive trays: The drive trays are all hot-swappable. If a hard drive fails, it can be replaced while the subsystem is still running.

Open flap: Once the flap on the drive tray has been opened, the drive tray must be removed from the subsystem. Failure to remove the drive tray from the subsystem after the flap has been opened may result in signal glitches and Data Compare Errors might ensue.
