Narrow to Wide SCSI Upgrade Instructions Page 11

PDI-00440-70, Rev. A01

If you are connecting narrow SCSI devices to a Wide SCSI cable, be sure to use the

appropriate adapter between the device and the cable connector.

3. Mount the new Wide SCSI cable/adapter plate assembly onto the existing SCSI cutout using the

standoffs provided with your upgrade kit.

4. Make sure the Wide SCSI cable is terminated properly. This normally means plugging an

external active terminator into the external Wide SCSI port on the rear panel. This terminator is

included in your upgrade kit. Fasten the thumbscrews to secure the terminator. See Appendix A

for more information about SCSI bus termination.

5. If you are adding a disk or tape drive, don’t forget to attach the DC power cables from the power

supply to it. Refer to your computer’s service manual for peripheral installation instructions.

Finishing Up

After completing the upgrade, remember to enable Wide SCSI operation on your system. Refer to

your computer’s owner’s manual for more information on enabling Wide SCSI operation.

You have completed the upgrade. Boot and test your system before replacing the computer's cover, in

case you need to make some adjustments. Refer to your computer’s owner’s manual for more

information on testing procedures.

Once your system completes the testing procedures successfully:

1. Attach the computer cover with the existing seven screws.

2. Reconnect the power cord.

RACK MOUNT CHASSIS

This section describes how to install the Wide SCSI cable kit (PDB-00440-74) in a rack mount chassis.

While your computer's hardware is exposed and the AC power cord is unplugged, the components

are vulnerable to damage caused by static discharge. Before you handle any computer hardware,

make certain your work area is properly protected against static discharge.

Accessing Your Hardware

1. Power down your computer and unplug the power cord.

2. Unplug and clearly mark all cables from the rear panel.

3. Unlatch slides and carefully slide the rack out of the system.

4. Remove the seven screws that hold the top cover to the chassis.

5. Lift the top cover off and place it out of the way.
