2.2.4.3 Making External SCSI Bus Connections

This section provides step-by-step instructions for making external SCSI
bus connections.

Step 1.

Plug the 68-pin VHDCI connector on one end of a shielded
external high density cable (see

) into the host

adapter connector J2.

This connector is exposed on the back panel of your computer.

illustrates where this connection is made.
