Handling precautions

1. Do not cover the breather hole! Covering the
breather hole may result in loss of data.

2. Do not press on the drive! Do not apply any force
to the drive during handling or installation.

3. Always handle the drive with care to prevent
damage from shock, vibration, or electrostatic
discharge (ESD).

4. Do not open the static-protective bag containing
the drive until required. Static electricity can damage
the drive.

5. Turn off and unplug your computer before
removing the case.

6. When you are installing the drive, touch the
static-protective package containing the drive to a
grounded, unpainted metal surface for at least two
seconds. (This drains static electricity from the
package and from your body.)

7. Handle the drive carefully by the edges. Do not
touch any exposed printed circuit board.

8. Save your drive packaging materials including the
ESD bag in the event that the drive must be returned.
Place the drive in an anti-static bag before placing it in
the shipping container. The warranty will be void if
the drive is not returned in IBM approved packaging.

Installation procedure

It is advisable to backup all data before proceeding
with the installation.

This procedure may require the use of a bootable
System Diskette containing FDISK.COM and
FORMAT.COM

Setting the address

1. Each drive on the SCSI bus must have a unique
address. Fifty pin (narrow SCSI) devices have 8 pos­sible addresses with address 7 (highest priority) norm­ally reserved for the controller. Sixty-eight pin (wide
SCSI) devices have 16 possible addresses (0-15) .

2. Jumper positions 4 (68 & 80 pin only), 3, 2, and 1
of the 12 position Option Jumper Block are used to
select the SCSI device ID. The shipping default is ID 6
(jumper positions 3 and 2).

Attaching the drive

1. Turn off the computer, unplug the power cord, and
open the case.

2. The DCAS drive requires Active Termination on
both ends of the SCSI cable (the SCSI controller
normally provides internal termination for one end of
the cable). If the DCAS drive is the only device on the
SCSI cable, attach it to the end of the 68 pin cable
furthest from the controller and enable termination by
placing a jumper on position 6 of the Option Jumper
Block. If the drive is attached to a cable that contains
other devices and the new drive is not attached to the
end of the cable, jumper position 6 must be open and
Active Termination must be supplied by the device at
the end of the cable.

3. Select the other option jumpers as required by your
computer.

4. Attach the power connector.

Mounting the drive

1. Mount the drive securely, using the appropriate
brackets or rails, in any axes, using four 6-32 UNC
metric screws in the bottom or side mounting holes.

2. The maximum screw insertion depth for bottom
mounting is 6.0 mm (.23 in) and for side mounting is

3.5 mm (.14 in).

Configuring your Computer

1. Plug in the power cord and power on your com­puter. Consult your SCSI adapter users guide for
information on configuring a new hard disk drive.

2. Follow the Operating System instructions to format
and partition your drive.

If your system will not boot up after complete instal­lation, recheck all settings. If the system still fails to
boot up, remove the new drive to return the system to
its original configuration and call the IBM Hard Disk
Drive Technical Support Center.
