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 dis-
charge (ESD).
4. Do not open the static-protective bag with 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

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

This procedure may require using 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.  Sixty eight and eighty pin (Wide SCSI)
devices both have 16 possible addresses 0-15).
2.  SCSI address bits 3, 2, 1, and 0 of the 32-pin  
Jumper Block are used to select the SCSI device ID.
