Install or replace disk drive with the system powered off
You might need to install or replace a Small Computer System Interface
(SCSI) disk drive in a system with the power off. Use the procedure in this
section to perform this task.
Complete the
following steps to install or replace a SCSI disk drive.
Note: Some
of the figures in these procedures might not look exactly like the system
or expansion unit that you have. However, the steps to perform the task are
the same.
Disconnect the power source from the system by unplugging the system.
Note: This system might be equipped with a second power supply. Before
continuing with this procedure, ensure that the power source to the system
has been completely disconnected.
Push the drive-cage release tab A up and
rotate the drive cage all the way out of the system until it locks into place
over the drive-cage retention tab, as shown in the following figure. The open ends of the drive slots and installed drives will face you.
Figure 1. Rotating the drive cage out of the system
Slightly pull the fan assembly edge outward to release the tabs
and rotate the fan assembly to the side, as shown in the following figure.
Figure 2. Opening the fan assembly
If your system has preinstalled hard disk drives in the drive cage,
carefully disconnect the power and signal cables from the back of the drives.
Figure 3. Unplugging cables from the disk drive
Remove the disk drive or the empty drive tray from the drive bay
in which you want to install the drive. Grasp the blue drive tray
and pull the drive out of the drive cage.
Figure 4. Removing the drive tray
If you are replacing a disk drive, remove the drive tray from the
disk drive that you pulled out of the system. Gently pull out
on one side of the drive tray and pull the drive out of the drive tray, as
shown in the following figure.
Figure 5. Removing the disk drive from the
drive tray
Touch the protective package containing the new drive to any unpainted
metal surface on the system. Then, remove the drive from the package
and place it on a protective surface.
Determine the next available disk drive position in your system. For information, see Disk drive locations.
Note: When
you have a system with an expansion unit, fill the slot positions in the system
unit first. However, you can choose a different disk drive placement depending
on your data protection strategy.
Install the disk drive
Select the slot where you want to install the
disk drive.
Install the disk drive on to the drive tray by aligning the guide
pins on the drive tray with the guide holes on both sides of the disk drive,
as shown in the following figure.
Figure 6. Attaching the disk
drive to the drive tray
Align the drive assembly with the guide rails in the drive bay.
Tip: Make sure that the connector end of the drive is facing
you.
Gently slide the drive assembly into the drive
bay until the drive snaps into place.
Figure 7. Installing the
disk drive
If you are installing more than one disk drive, repeat step 1 through step 4 until
all disk drives are installed.
Complete the installation
Connect the applicable signal cables into the back of the drive,
as shown in the following figure.
Figure 8. Plugging the cables
in to the disk drive
Connect the power cables to the back of the drives. The
connectors are keyed and can be inserted only one way.
Note: There are three
cables to plug in to each drive.
Close the fan assembly over the disk-drive cage, as shown in the
following figure.
Tip: Route the cables
through the holes on either side of the fan assembly.
Figure 9. Closing
the fan assembly
Push the disk-drive cage slightly forward, press the release tab A,
and lower the cage into the system, as shown in the following figure.
