CONNECTING SECONDARY DRIVES

The secondary drives are connected to the computer via the primary disk
drive.  The drives must be stacked with the primary drive on top of the
secondary drives.

Locate the secondary hard disk expansion cable.  Connect one end to the
Control In connector of the secondary drive and the other end to the
Control Out connector of the previous drive in the chain.  If you have only
two hard disk drives, this connector connects to the primary drive.

If you have another secondary drive, connect the second secondary hard disk
expansion cable to the Control Out connector and the other end to the
Control In connector of the next drive in the chain.

Locate the data cable.  Connect one end to the appropriate data connector
(A for the first secondary drive, B for the second, and C for the third).
Connect the other end to the Data In connector on the secondary drive.
