Specifications

❏ If you install only internal devices on the SCSI interface, then
the SCSI adapter card is the last device on the interface. If you
install only external devices on the SCSI interface, then the
SCSI adapter card is the first device on the interface. In either
of these cases, leave the terminators on the SCSI adapter card.

❏ If you install internal and external devices on the SCSI
interface, then the SCSI adapter card is in the middle. In this
case, remove the terminators from the SCSI adapter card.
The first and last devices on the interface must have their
terminators installed, and all other devices must have their
terminators removed.

❏ If you attach a device with internal terminators that cannot be
removed, it must be the first or last SCSI device on the

affect the device’s operation speed.
