Handling precautions
Ÿ
Do not open the electrostatic discharge (ESD) bag
containing the drive until required.
Ÿ
Do not apply pressure on the drive during handling
or installation.
Ÿ
To prevent damage from impact or vibration
always set the drive down gently.
Ÿ
Handle the drive carefully by the edges. Do not
touch the exposed printed circuit board or any
electronic components.
Ÿ
Do not cover the breather hole! Covering the
breather hole may result in loss of data.
Ÿ
Save the packaging materials including the ESD
bag in the event that the drive must be returned.
Installing the drive
1. Backup all data.
2. Record the serial number and part number of your
hard drive for future reference.
3. Turn off the computer and remove the computer
system cover.
4. Before handling the hard disk drive, discharge any
static electricity from yourself and your clothing.
With one hand touch an unpainted metal surface
on your computer chassis, then touch the ESD
bag with the other hand for a minimum of two
seconds. Remove the hard drive from the ESD
bag.
5. Unplug the computer.
6. Assign a SCSI address to the drive by installing a
jumper on one or more ID bits on jumper block J-4.
Refer to the following illustrations. In the table
opposite, 'X' means that a jumper is placed on that
ID bit position.
