Terminating the drive

If you are installing the drive in a system that has other

SCSI devices installed, terminate only the end devices

on the SCSI chain. A SCSI “device” is any disc drive,

scanner, tape backup unit, or other piece of hardware

connected to your system using the SCSI bus.

The top example in Figure 3 shows an internal hard disc

at one end of the SCSI bus with the SCSI controller at the

other end (both are terminated). The bottom example

shows two additional SCSI devices connected exter-

nally—this means the SCSI controller is no longer on the

end of the SCSI chain and should not be terminated.
