Removing and Installing Parts 105
SCSI devices installed by Dell are configured correctly during the
manufacturing process. You do not need to set the SCSI ID for these SCSI
devices.
If you attach additional optional SCSI devices, refer to the documentation
for each device for information about setting the appropriate SCSI ID
number.
NOTICE: Dell recommends that you use only SCSI cables purchased from
Dell. Cables purchased elsewhere are not guaranteed to work with Dell
computers.
Device Termination
SCSI logic requires that termination be enabled for the two devices at
opposite ends of the SCSI chain and disabled for all devices in between.
Dell recommends that you use terminated cables and that you disable
termination on all devices. See the documentation provided with any
optional SCSI device you purchase for information on disabling
termination on the device.
