Understanding SCSI connectionsRead the following sections to dete rmine how to set up your SCSI
devices and whether you need any optional SCSI cables.
Daisy Chain
The SCSI interface allows you to connect up to seven devices (such
as a scanner, hard disk, CD-ROM, and so on) to the computer, in what
is called a “daisy chain” arrangement. Only the first SCSI device in
a daisy chain is connected to the computer; each of the other devices
is connected to another SCSI device.
SCSI Cables
You ma y nee d t o p ur ch as e S CS I c ab les be fo re se tt in g u p y ou r S CS I
daisy chain. Be sure the SCSI cab le connectors are suitable for you r
hardware, depending on the maker of your SCSI device and SCSI
interface board.
SCSI ID and terminator
Each device has a SCSI ID number: the computer is usually
number 7, and each of the other devices must have a different
number between 0 and 6. Also , the first device and the last d evice
in the chain (not including the computer) must have a terminator.
No other device can have a terminator, or if a terminator does
exist, it must be turned off or removed.
