Daisy Chaining

As an optional configuration, two AIT tape drives can be connected to the same SCSI 
channel at the same time. Use no longer than a 6-ft cable to attach the intial drive, then 
use no longer than a 3-ft cable to daisy chain the additional drive.

IMPORTANT:  Do not connect more than two drives per SCSI controller.

1. If the first drive has a terminator on the SCSI connector 

2

, remove it.

2. Connect the tape drives together by placing a SCSI cable between the SCSI 

connector 

2

 of the first drive to the SSI connector 

3

 of the second drive.

3. Place the terminator (not shown) on the SCSI connector 

4

 of the second drive.

4. Power ON all peripheral devices.

5. Power ON the computer.
