Models: DCHS-04F, DCHS-04W, DCHS-04E,
DCHS-04S, DCHS-04U, DCHS-04X, DCHS-04Y,
DCHS-09F, DCHS-09W, DCHS-09E, DCHS-09S,
DCHS-09U, DCHS-09X, DCHS-09Y

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. Remove cover.

6. When installing the drive, touch a grounded,
unpainted metal surface with the static-protective
package containing the drive 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 the drive packaging material 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.

Quick installation procedure

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

This procedure may require 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 eight
possible addresses (0-7) with address 7 (highest pri­ority) normally reserved for the controller. Sixty- eight
pin (Wide SCSI) devices have 16 possible addresses.

2. SCSI address bits 3 (68- & 80-pin models only), 2,
1, and 0 of the 32-pin Option Jumper Block are used
to select the SCSI device ID.

Attaching the drive

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

2. The DCHS 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 DCHS drive is the only device on the
SCSI cable, attach it to the end of the cable furthest
from the controller and enable termination by placing
a jumper across pins 13 and 14 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, the jumper across pins 13 and 14
must be removed 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 mounting
is 3.8 mm (.15 in).

Configuring your computer

1. Plug in the power cord, insert the System Diskette
and power on your computer. Your computer may
detect a configuration change and prompt you to pro­ceed to the Setup screen. If so, proceed to step 3.

2. If your computer does not prompt you to enter re­configuration, enter your computer’s Setup, typically
by key selection or keyboard combinations during
power-on or during a reboot. Refer to your computer’s
documentation for the proper key sequence.

3. Follow the Setup menu to configure your computer
with your new SCSI drive. It may be necessary to
restart your computer for the changes to take effect.

Partitioning and formatting (using DOS 5.0 or
later)

Caution! Be sure that you select the correct hard
drive. Partitioning and formatting will erase all data.

1. At the DOS prompt type FDISK, press [ENTER],
and follow the instructions on the screen.

2. To format the primary system drive, type FORMAT
C:/S at the DOS command prompt and press
[ENTER]. The /S parameter makes C: the operating
system startup drive.

3. To format a second drive (not C:), type FORMAT X:
(where X is the drive letter assigned by FDISK) at the
DOS prompt and press [ENTER]

4. Remove the diskette and restart your computer.
The installation is complete.

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.
