INSTALLATION GUIDE

Each device on the same SCSI chain must have a unique ID, otherwise your system

will not work properly and data corruption may occur.

You should be able to see the SCSI ID of each external SCSI device on its enclo-

sure. Refer to each device’s manual for detailed instructions on checking and set-

ting its SCSI ID.

CAUTION! For best data integrity, DO NOT connect your ORB

SCSI Drive on the same SCSI chain as SCSI-1 devices.

3. Assign a unique SCSI ID to your ORB SCSI Drive.

You can find the ORB drive’s ID switch either on the bottom of the drive (as shown

on page 5, Figure 4a) or on the side of the drive (as shown on page 5, Figure 4b).

The available IDs for the ORB Drive are ID 0, 4, 5, and 6.

If your ORB Drive has a rotary switch as shown in Figure 4a, you will need a #0

Phillips screw driver to change its ID setting

4. Connect one end of the supplied cable to the ORB Drive’s SCSI-IN

connector (left connector when facing the rear of the drive).

5. Find the SCSI connector on the rear of the computer or an existing

SCSI chain.

A SCSI connector is labeled or with the acronym SCSI. Check to see if the SCSI

connector fits the other end of your cable. If not, you need to purchase an appropri-

ate SCSI cable or adapter from a computer dealer.

If you are using a PowerBook, you will need a special PowerBook cable. The cable

has a square 29-pin SCSI connector on one end. Refer to figure 7 on page 6.

6. Connect the ORB SCSI Drive to the computer or an existing SCSI

chain.

Connect the other end of the supplied cable to your computer’s SCSI connector or

an existing SCSI chain.

To achieve Ultra SCSI performance, refer to Section 2.7, Ultra SCSI Performance.

7. Attach another SCSI device to your ORB Drive, if applicable.

If you want to attach another device to your ORB Drive, connect its cable to the

ORB Drive’s SCSI OUT connector (right connector when facing the rear of the

drive). You may need an adapter if the connector on the cable is not HD50.
