other connectors on the ribbon cable, as shown in Figure 3-7.

Connecting External SCSI Devices

You can daisy chain up to seven external SCSI devices to the external

connector on the host adapter. Daisy chaining means connecting mul-

tiple devices in a series, as shown in Figure 3-8. A cable runs from

the external host adapter connector to the first external device; a sec-

ond cable connects the first external device with the second external

device; and so on.
