Step 1.

Plug the 68-pin connector on the SCSI ribbon cable into the
internal connector on the host adapter board.

Figure 2.3

illustrates how to make this connection.

Step 2.

Plug the 68-pin connector on the other end of the internal SCSI
ribbon cable into the SCSI connector on the internal SCSI
device.

Figure 2.4

illustrates the chaining of internal SCSI

devices.

If you have more than one internal SCSI device, you must have
a cable with at least as many connectors as you have devices.

Note:

Daisy chaining devices represent an arrangement of
devices connected in a series. Any signal transmitted to the
devices goes to the first device, from the first to the second,
and so on. Termination occurs on the last internal SCSI
device.

Section 2.3, “Terminating the SCSI Bus,”

information on SCSI bus termination.
