Detailed Installation Procedure

2-15

Step 3.

To connect more than one external SCSI device to the host
adapter, chain them together with shielded external SCSI
cables. See the example in

Figure 2.11

.

Figure 2.11 Multiple External SCSI Devices Chained Together

2.2.4 SCSI Bus Termination

The devices that make up the SCSI bus are connected serially (chained
together) with SCSI cables. The first and last physical SCSI devices
connected on the ends of the SCSI bus must be terminated. All other
SCSI devices on the bus must have their terminators removed or
disabled.
