Configuring the new SCSI drive
If your computer contains SCSI devices, they are connected to a SCSI host
adapter add-in card.
To configure SCSI devices correctly on the SCSI cable, you must designate
(terminate) the ends of the chain and determine the order of the links (IDs)
between the ends of the SCSI chain.
Termination
A SCSI device has a terminator jumper which can be set to On (for the last
device on the cable) or Off (for devices in the middle). The terminator jumper
on the last device should be set to Off if the cable has a terminator plug attached
to the end.
Generally, your computer’s SCSI host adapter is at one end of the cable and a
terminated device or terminator plug is at the other. The SCSI host adapter can
be set so you can start up from any device on the SCSI chain.
