Understanding SCSI connections
Read this section to determine 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 may need to purchase SCSI cables before setting up your SCSI
daisy chain. Be sure the SCSI cable connectors are suitable for your
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 device
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.
